Regional and Mesoscale Meteorology Branch

00:00:01:09 – 00:00:20:08
Speaker 1
Okay, this is Scott, and I’m going to be talking a little bit about the severe weather that happened over, mostly Oklahoma and a little bit of Arkansas and Missouri. Middle of last week on the 25th. You can see the storm reports on your screen right now. And I know that people from the offices around there. So feel free to chime in.

00:00:20:11 – 00:00:48:05
Speaker 1
I’m just going to show you some of the, satellite products that may have been useful for that time. And I’m going to show you two different views. First is the initial part of the development. So before the really strong thunderstorms happened, but there were still some hail ers before that line of, severe weather formed, maybe from East west, southwest to east southeast, from around just north of Oklahoma City, up toward Tulsa.

00:00:49:03 – 00:01:08:08
Speaker 1
So the first thing I’m going to show you, what, is so this is just an animation very early on. This is looking at the cloud top cooling, which is a product. You can look at an ellipse. And this is telling you which storms are initially or which storms are showing strong cooling. At the cloud top.

00:01:08:08 – 00:01:32:24
Speaker 1
So you’re looking at the top of the cloud. You’re looking at the brightness temperature at 10.7 microns. And if that’s cooling very quickly, then you know, you have a lot of strong, fertile vertical growth in that storm. So you can relate maybe that strong initial growth in the storm to maybe the potential for something happening in the in the very near term.

00:01:32:26 – 00:01:38:24
Unknown
That product is also combined with some radar products to.

00:01:38:26 – 00:01:44:17
Speaker 1
To generate, what’s called the prob severe product. And that’s what’s animating here. I’m hoping.

00:01:44:17 – 00:01:51:12
Unknown
You’re seeing. And it’s not a quick animation. So I’m hoping I think most of the images that are there, and we’re focusing on the storm that’s crossing.

00:01:51:12 – 00:02:15:28
Speaker 1
Into, I’m afraid I don’t know, my counties in Arkansas and northwest Arkansas, but it’s crossing into Arkansas just after 20 is. See, the props up here is defined as a, probability that a storm will first produce severe weather in the next 60 minutes, and typically the benchmark that’s used. And again, we’re looking at the storm over Arkansas.

00:02:15:28 – 00:02:32:03
Speaker 1
You know, the stuff that’s forming over northeast Oklahoma as well, that’s going to be, develop into something stronger than this one inch hail or over Arkansas. But this is interesting because the I’ll show you a slower loop of this storm next. So.

00:02:32:03 – 00:02:36:25
Unknown
This is a kind of a full blown, blown up first, I think a 20.

00:02:36:26 – 00:02:53:00
Speaker 1
320 or to the 20 or 40. So every time miss updates. So I guess I should back up and say what goes into this prob severe. It looks at the like can you can see in the readout there it looks at the environmental most unstable.

00:02:53:00 – 00:02:57:20
Unknown
Cape and the shear that’s coming from the rapid refresh.

00:02:57:20 – 00:03:20:06
Speaker 1
So it’s looking at the general environment of the of the it’s looking at the general environment, and you and that’s helping to gauge how strong the strongest might become. So it’s like it’s got the Cape and the shear. And again, that’s from the rapid refresh. Underneath that is the miss mesh. Maximum expected size of hail.

00:03:20:15 – 00:03:35:29
Speaker 1
That’s one of the predictors as well. And then the next two are the vertical growth rate, given in percent of the troposphere per minute. And then the glaciation rate, which is.

00:03:36:01 – 00:03:42:15
Unknown
Given as a percent per minute as well. And then there are some, phrasing after that.

00:03:42:15 – 00:04:08:05
Speaker 1
So the vertical growth rate for this particular storm was strong and the glaciation rate was moderate. And you can see that 2.86% per minute. So over the course of 15 minutes, that’s going to climb through, more than 30% of the troposphere. So we have this prob severe, severe, probably there’s 33% that 45%, 45% at 24.

00:04:08:05 – 00:04:37:00
Speaker 1
Then it jumps at 87% at 26. The fact that the one inch hail was reported at 25, so this, wasn’t necessarily a hit for this particular, algorithm because it’s really looking at now when it gets above 50%, it was only at 45%. So this was but it’s showing how this is tracking the correct, the correct storm that is eventually going to become severe.

00:04:37:02 – 00:04:56:21
Speaker 1
And there’s another example of this up over there. Over, Missouri crossing into from Kansas into Missouri about the same time. That’s doing the same thing, but it’s doing a bit, a little bit better. I really should have shown that one because it is becoming greater than 50% and it gets up to 90%. And then it, generates hail.

00:04:56:23 – 00:05:30:18
Speaker 1
So that’s a product that you can use that, will help you monitor the storms as they’re evolving in time and again, the probability that the storm will first produce severe weather, it doesn’t differentiate between hail, high winds or tornadoes. But you’ll notice that one of the predictors there is the mesh. So, my inclination is that this does a little bit better with hail than other types of, severe weather and of course, subject to how much shear you have or how much CP you have.

00:05:30:20 – 00:05:36:14
Speaker 1
Okay. I wanted to talk a little bit more about some other things that you can use here.

00:05:37:24 – 00:05:43:15
Unknown
For me, NPP soundings, so-called new Cap soundings are now in a website.

00:05:43:25 – 00:06:09:12
Speaker 1
They do have some nice, overcast times for the central part of the U.S. you’ll notice the times on these particular soundings are at 1833 UTC. It takes about, an hour to 90 minutes for them to get in the ellipse. I’m going to load up my I’m just going to really quickly load it up right now to see what which passes in my ellipse right now while I’m talking.

00:06:10:03 – 00:06:28:24
Speaker 1
So it’s just up to 19 C and I can see the, 1730 C, new cap soundings are in right now. That’s mostly on the East Coast right now. So the next one which will be coming in, probably in about 90 minutes, will be over the central part of the U.S.

00:06:28:24 – 00:06:36:00
Unknown
So I hope you can see the red and the, the red and the yellow.

00:06:36:07 – 00:07:00:26
Speaker 1
Flashing arrow there. I’m just going to show you two soundings from this. Just show you what kind of information you can get from it. So here C sounding in kind of more of north western Arkansas. Or was that in Oklahoma? Okay. It’s southeast between 12th and Fayetteville. And I adjusted it as well. So we have two soundings here.

00:07:00:26 – 00:07:26:00
Speaker 1
The one that’s a little, drier at the surface is shown for, there are two soundings there. One is a little bit drier at the surface. That’s the initial sounding. Then I modified it, to make it more in line with the observed temperature and dew point in the surrounding. So that mostly meant, I believe I changed a chance at dew point temperature from 13.7 to 15.7.

00:07:26:03 – 00:07:51:20
Speaker 1
And that changed. That came from around 1800 up to 2600. So that’s up in the region. That’s just southeast of where the strongest thunderstorms formed. So it’s that an additional bit of information that you can look at. I’m trying to understand exactly what kind of environment these storms will be forming in. And this is the the yellow one was a little bit farther to the south and not quite as, unstable.

00:07:52:02 – 00:08:16:22
Speaker 1
You could say that maybe it, that there were some thunderstorms earlier in the day and in the southern part of this domain, so maybe there’s still some stable air left around. But again, I modified this one as well. Change that dew point from 14 to 16. And the Cape went from 1400 to 2200. So some of them I’ve got some pretty nice amounts of cape for these, for these storms to, feed on.

00:08:16:22 – 00:08:39:08
Speaker 1
I just wonder if there if there are any questions on this initial storm, before the real action, but before the real action going. And I’m also kind of curious if you’re using new caps in your offices. So, I know we have from Amarillo, Midland and Tulsa on. And I just start with Tulsa. Enough. Do you are you looking at the new cap soundings?

00:08:39:17 – 00:09:02:19
Speaker 1
No, I was not aware of these. Are you? If you have a website, you know. Well, that’s why when you when you get ups to, new cap soundings are available in their website, you they’re not an alias of one. Okay, so one other question I had and you can get back to it after the others. But on the one storm that left Oklahoma went into Arkansas, there’s Crawford County, Arkansas.

00:09:02:21 – 00:09:22:05
Speaker 1
We had the hail report early. It looked like the, it looks like a little white box around it or indicating it was severe. It went away, and then it didn’t come back for a little while. What, am I reading that wrong or looking at it wrong? I would go away. Well, the the, Are you talking about the contours around the.

00:09:22:07 – 00:09:43:07
Speaker 1
Yeah. The contours. So the contours are changing color. The the color scale is up in the upper left. And when the, when it gets into white, it’s, it’s crossed 50%. So it’s blue at the beginning. Then it gets kind of more of a cyan color when it’s 45%, then it’s 87%. So, sorry. My eyes.

00:09:43:09 – 00:10:10:10
Speaker 1
Okay. Or in your projection system, you can blame that too. But yeah. So this, I would have liked to have this problem prob severe go above 50%. Maybe at 2020, up at 23 versus 20 or 40, if the hell was going to be at 20 or 50. But, I like how it’s tracking the storm that’s actually going to be producing the hail before the hail forms.

00:10:10:10 – 00:10:29:28
Speaker 1
That’s I think that’s pretty handy. Yeah. I’ll let you talk for the a which two offices now? Yeah. So, Midland and Amarillo are you do you have any tips to. I guess I should ask that question first. And then I should ask if you’re if you’re looking at the. Yeah, if you’re looking at the new cap sounding roaster.

00:10:30:00 – 00:10:35:25
Speaker 1
No, I don’t think there are any with two offices on the call right now. Oh my goodness. I feel like it’s 1997.

00:10:35:25 – 00:10:42:14
Speaker 3
Or something that’s just waiting to come out to Midland. And we’re partying like it’s 1999. Okay.

00:10:42:14 – 00:11:09:10
Speaker 1
Well definitely the Wild West out here. Well, these are things you’ll be able to you and the crops are bigger is also a, a two product because it’s it’s, because of some of the software choosing to help display it. So things you’ll be able to use. When are you scheduled for the install? I thought that was almost finished August 4th in Amarillo.

00:11:09:12 – 00:11:31:12
Speaker 1
Wow. Okay. June in Tulsa. WFO Dodge Lira. What’s two? I guess I must have missed the call for offices, but, While we do have that new caps in there, I’m not aware that anybody’s been looking at it. Okay, I’ll just repeat, I know if you were here at the beginning of this, but, it does have a good time for the swath of the middle part of the country.

00:11:31:12 – 00:11:53:21
Speaker 1
So, for late afternoon convection, you’ll get a pretty up to date reading. For what kind of instability? That if especially for the gradients. Instability? What kind of instability you have to work with? It’s the implementation is not easy to use because you have to push on individual soundings. And I’m always forgetting which sounding I’ve looked at.

00:11:53:21 – 00:12:02:20
Speaker 1
I have to wonder things come back up when the display of green dots comes back up, because I can never remember which one they pushed. But it does give you a lot.

00:12:02:20 – 00:12:08:14
Unknown
Of, interesting information that you can, maybe use in your forecast, when you’re.

00:12:08:14 – 00:12:17:17
Speaker 1
Making your forecast. Okay. I want to talk next about the second round of stuff.

00:12:17:27 – 00:12:24:02
Unknown
Okay. So this is an animation that Scott Bachman put together.

00:12:24:04 – 00:12:43:14
Speaker 1
And I believe he’s on the call. Just showing the development from the ghost perspective of the stronger convection that formed, you know, aligning east, north west, southwest to east northeast. And the one that, ultimately produced a fatal tornado just west of TOF, I believe, in Tulsa County.

00:12:45:06 – 00:12:48:21
Unknown
So I there are a couple of things I really like about this image.

00:12:49:10 – 00:13:24:24
Speaker 1
One is the wave clouds that you can see, the horizontal roof, the horizontal wall cloud. You can see the beginning that are kind of showing you in the boundary layer where I think where you have to focus attention. If you look at this, really carefully, look at the southern boundary of this region where you had the horizontal wave clouds and a little bit later on, if you just if I just keep putting this here, this is where I noticed this could just be coincidence, but that is where, that is how the storms align themselves with the end of this.

00:13:24:27 – 00:13:43:27
Speaker 1
So that was kind of missing. And there’s also a very, cool storm or very strong storm because, where I put the cursor, if you look at the storm that forms there, you’ll see a nice, I think I’ve lost the word, but it’s have kind of a bold front. So it’s put up an obstacle to the flow, and you can see the flow flowing all around it.

00:13:43:27 – 00:13:55:02
Speaker 1
So you see the V, the V right there. That’s just, really interesting to look at. So very nice. Strong convection formed and the ghost imagery, you have these properties.

00:13:55:02 – 00:14:01:11
Unknown
Borders are where vertices in the boundary layer at the beginning kind of saying, well,

00:14:01:14 – 00:14:04:13
Speaker 1
This might be where something interesting is going to happen.

00:14:04:15 – 00:14:10:29
Unknown
There are other things that you could have used here. So this is an animation of,

00:14:11:02 – 00:14:35:24
Speaker 1
The total precipitable water. So it’s this is from the coast instrument. So this is something that you can get in, a website because the, is the total precipitable water from goes is in a what? And this is showing the frontal analysis plus the pooling of the total precipitable water, I believe the total, the highest total precipitable water got over 1.5in in that region.

00:14:35:24 – 00:15:04:22
Speaker 1
That’s, just to the west of Tulsa. So a really nice feed of moisture coming into the, convection that’s coming up from the west southwest into Tulsa. That’s from the go, sounder. You can also do the same thing. Here’s a here’s a snapshot. This is Motus total precipitable water plus a visible image. So again, you see this really nice, ton of moisture, potentially feed any kind of convection that’s going to be just going to be forming.

00:15:04:22 – 00:15:15:07
Speaker 1
So this is a 19 C, I believe the tornado was a 20 to 34, near Tulsa. This is Bryan.

00:15:15:07 – 00:15:33:09
Speaker 3
At W for Midland. There’s a couple things here that, in the visible imagery that are, maybe telltale signs of an increased, area of, subclass helicity. If you could. I don’t know if you could freeze Scott’s animation.

00:15:33:09 – 00:15:35:21
Speaker 1
I’m afraid I can’t. This is just an animated gif.

00:15:35:28 – 00:16:03:05
Speaker 3
Okay, well, you’ll see there. Now, the original, warm, friendly look to me. Original warm front lifted north of Tulsa. And Steve, Amber, you may correct me this am my wrong, lifted. Well, earlier. Well, prior to, convective initiation of the storm that ultimately results in the, f two tornado in Sand Springs, which, incidentally, is my hometown.

00:16:04:07 – 00:16:32:28
Speaker 3
If you look at the if you look at the horizontal convective rolls, you’ll see that, in, in our area, maybe, southern Osage, northern Pawnee counties, west Tulsa, there appears to be a kink in the direction of those cars. They they were trending north south. And in this case, we’re trending more northwest southeast until they hit the front.

00:16:33:00 – 00:16:35:24
Speaker 1
Now, so straight right through air.

00:16:35:26 – 00:17:06:22
Speaker 3
Could result in, perhaps higher, storm relative helicity being ingested into the storms, and particularly one that, ended up going through, Sand Springs and parts of Tulsa. So that was kind of an interesting clue there. Also, at the surface, I noticed that it was amazing. It say, I believe it’s in Pawnee County. Prior to see the winds backed quite a bit.

00:17:06:25 – 00:17:14:12
Speaker 3
And again, that might be, that might be supportive of the ACR kind of kicking more northwest southeast and also.

00:17:14:12 – 00:17:16:15
Speaker 1
Speaks to some kind of boundary there that would be, you.

00:17:16:15 – 00:17:43:15
Speaker 3
Know, colliding right along the secondary waterfront or some kind of trough. I’ve not done a surface analysis, so I couldn’t I couldn’t say, Steve is more of a optician than I am. Maybe he can chime in, but, it looked to me that there was that area once I saw the kinks in the cars that told me that, that area now was at a higher risk of, tornado genesis, all the things being equal.

00:17:43:17 – 00:17:52:27
Speaker 1
Right?

00:17:53:00 – 00:18:23:04
Speaker 1
Okay. I just want to show one other, satellite derived product. And this is the, satellite derived cape from the coast sounder. Also showing, fairly high values of Cape. Those red values are around 4000. So a general area of 2 to 3000 in the morning with destabilization, up to around 4000 by 1980. And, there’s some purple 5000 there.

00:18:23:14 – 00:18:46:09
Speaker 1
There are a lot of clouds around. I ask, I I’ll start to wonder if there’s just 1 or 2 pixels, and there’s a 5000 next to the cloud. Exactly what’s going on. But, plenty of things saying that. Yes. Convection. There’s a there’s plenty of instability here. If you had the correct shear profile, to generate some severe weather.

00:18:46:18 – 00:19:05:17
Speaker 1
I think those are the images I showed that I have to show. I have some longer animations, but, sometimes longer animations on a, Well, I guess I should ask, have you been able to see all the animation so far? Maybe I’ll just put up the really long, visible animation that I have for the entire day.

00:19:05:27 – 00:19:06:27
Speaker 1
And hopefully you can.

00:19:07:00 – 00:19:12:16
Unknown
See the whole thing, and hearing. No, no one’s saying no, I haven’t seen anything.

00:19:12:16 – 00:19:25:01
Speaker 1
Let me see if I can find,

00:19:25:04 – 00:19:25:27
Unknown
So this is just from.

00:19:25:27 – 00:19:57:27
Speaker 1
Start to finish. Over showing the, so you see the initial convection over, Arkansas, southwestern Arkansas. Then we have, you know, obviously a couple boundaries here. There’s so there’s a boundary that seems to be over western Arkansas and extreme eastern, Oklahoma in this image. And then we have the other boundary that the strongest convection form from is such west southwest to east, north to east, north east.

00:19:58:09 – 00:20:12:29
Speaker 1
So just a really interesting, and again, you can see those horizontal rule for the season, the boundary layer, those that are that have been mentioned already.

00:20:13:10 – 00:20:15:08
Speaker 1
That’s all I have. Dan.

00:20:15:10 – 00:20:39:17
Speaker 4
Well, let me, let me ask a question, maybe to Steve. There was some initial convection just southwest of Tulsa, right around there, moved off to the northeast, and then, later we had the storms go through Tulsa. Was there any possibility that that early convection, maybe late an outflow boundary down in the area of, Tulsa?

00:20:39:19 – 00:20:43:20
Speaker 1
I don’t think we saw anything on radar on that or, noticed anything about it.

00:20:43:24 – 00:20:59:06
Speaker 4
Okay, okay. I just, wondered since I, I saw it in the, the visible imagery here. So, any other comments on that particular, that Tulsa.

00:20:59:08 – 00:21:15:19
Speaker 1
I don’t think so. I think the kink in those horizontal rows of of of clouds, was kind of interesting. Something I’m going to try to pay a little more attention to and watch in the future. No, I don’t I don’t think so.

00:21:15:19 – 00:21:17:13
Speaker 3
It just it was an interesting day.

00:21:17:15 – 00:21:25:17
Unknown
Yeah, yeah, the first one.

00:21:25:19 – 00:21:32:05
Speaker 3
The, the sounding, image that you showed earlier, from the, I guess, the polar orbiting satellite.

00:21:32:05 – 00:21:36:24
Speaker 1
Right. How accurate do you think those are? In the lowest levels.

00:21:36:24 – 00:21:43:27
Speaker 3
Where we can be able to use that information to decide, when the cap is going to break?

00:21:43:29 – 00:21:46:20
Unknown

00:21:46:23 – 00:21:48:18
Unknown
Typically. Well, I mean, I.

00:21:48:18 – 00:22:11:03
Speaker 1
Haven’t I’ve probably only looked at 20 to 30 of them over the course of a year or so. I’m usually seeing, dew points that are too cool. So it’s a little bit too dry in the boundary layer. But the software allows you to edit, you can edit it so you can bring it more in line with the meteors, which is what I’ve done on this funding.

00:22:11:03 – 00:22:38:16
Speaker 1
This is that you’re seeing. So I think it’s it resolves the new caps are meant to resolve maybe ten layers in the entire troposphere. I mean, 20 temperature layer layers and the entire troposphere. Maybe less than half of those are in the troposphere. And maybe 9 to 10 moisture layers.

00:22:38:19 – 00:23:07:10
Speaker 1
But I think it is a fairly accurate depiction of the smoothed atmosphere of that. Right. And if you can add and because you can edit them in the, in the, in the end sharp, so when these are displayed, it brings up an end sharp editor. So you can edit them to make it, to make the surface boundary layer look a little bit more like, the meters may say it should be.

00:23:07:13 – 00:23:28:20
Speaker 4
And Scott, I think, one thing to point out is that, because of the inadequate vertical resolution, things like the strong capping inversions that you see in these elevated mix layers will be smoothed out. So it’s going to be hard to, you know, use those to really judge, when the cap will break those kind of questions.

00:23:28:20 – 00:23:53:06
Speaker 4
But what I think it could answer is in a, broader perspective, say, if you’re looking at 700, 500 lapse rates and maybe seeing the extent of how far those lapse rates, extend, maybe you’re looking at, where the elevated mix there exist in that respect. It might do better because it’s, you’re, you’re using a more smoothed out field, to begin with.

00:23:53:12 – 00:23:59:07
Speaker 4
But yeah, for looking at, at anything with very sharp inversions, it’s, it’s just going to be smoothed out.

00:23:59:08 – 00:24:07:22
Speaker 1
It’s a problem. Yeah. Okay. Thanks.

00:24:07:24 – 00:24:22:12
Speaker 4
Okay. Any other questions or comments on this? On this case, March 25th case.

00:24:22:15 – 00:24:26:22
Speaker 4
Okay. Scott, do you think I should take a couple minutes to look at some real time data or.

00:24:26:24 – 00:24:28:04
Speaker 1
Sure, sure.

00:24:28:06 – 00:24:34:29
Speaker 4
Okay. Or I’ll. I’ll go ahead and look at some real time. I just have a little bit,

00:24:35:02 – 00:25:02:13
Speaker 4
A little bit to show here. Here’s the visible imagery. And, in the water vapor imagery, if you look at, later here, there was a shortwave that was moving through Missouri and is out now off to the east, and some additional storms are going out ahead of that. But one of the questions will as well, additional storms form back, further to the west here across, southern Missouri.

00:25:02:15 – 00:25:27:27
Speaker 4
And this is the visible loop that’s, up to 1830. And you can see a cold front, coming down with northerly winds here. And then if we zoom in here in, southwest Missouri, I’ll go ahead and stop it. Okay. So, your bandwidth, this looks kind of choppy in the loop here. And you can see an area of enhanced cumulus here along this boundary.

00:25:27:29 – 00:25:51:01
Speaker 4
And, just bring up the surface ups, around this particular time, you can see southerly winds and, of course, another question in here is how much, destabilization takes place in terms of, getting some sunshine in here as well. So we do have an area of partly cloudy skies in here. And then a little bit more, cloudiness further to the east.

00:25:51:03 – 00:26:21:26
Speaker 4
So, you know, these are the kind of questions you’re looking at when you’re looking at the, visible imagery. Look a little further to the south and Arkansas and you can see these, stable wave clouds east to west, oriented across, central Arkansas, telling you about a stable airmass that’s in place here. And then further to the south, you can see this, what appears to be a gravity wave that’s moving through, northeast Texas in an area that’s, pretty strongly capped down here in the, Southern Plains.

00:26:21:26 – 00:26:39:05
Speaker 4
But if you look at the northeast edge of the lid, so to speak, up here in Missouri, it looks like we may get some, storms at the northeast edge of that in the vicinity of that front the next few hours or so. Those are some of those interesting things going on. Right now, any, comments or discussion about that?

00:26:39:11 – 00:27:10:05
Speaker 1
I was looking at the cape from the ghost sounder. Where is it? And, the minimum. And the cape really extends all the way back to Oklahoma City. So that’s it’s the instability has not cleared out. Has not moved out. I mean, I know I understand is underneath the cap. But there is Cape up to almost 4000, feet down just to the east of Wichita.

00:27:11:06 – 00:27:37:05
Speaker 1
What is Wichita Falls? Wichita Falls, kind of a corridor running, from Wichita Falls up to Tulsa. Then, then it falls off fairly rapidly to the northwest of that. So, I actually have it on my screen here if you want to pass it over. I have the Eagles keeper on my screen here.

00:27:37:07 – 00:27:42:04
Speaker 4
Okay, Scott, your we’re seeing your screen now.

00:27:42:07 – 00:28:19:23
Speaker 1
Okay. So as Scott was talking about, looking at the cape as derived from the South is coming out and goes and not able to build the in Texas, however it’s capped. But the area where it could and was talking about earlier. We see some values in the mid 2000, but it’s you know we still haven’t had it enough here and yet our capes up in a little bit higher.

00:28:19:25 – 00:28:23:04
Speaker 1
But yeah, yeah there’s, there is a long gated.

00:28:23:04 – 00:28:25:01
Speaker 3
Axis stability.

00:28:25:01 – 00:28:40:27
Speaker 1
There out ahead of that frontal boundary. But we just haven’t had anything that anything actually. Oh actually that actually pop up.

00:28:41:05 – 00:29:04:05
Speaker 3
This is Brian in Midland. I have a comment and a question. The comment is in, situations where you’ll see moisture return, underneath any ML, that crosses the Wash Tar Mountains in southeastern Oklahoma and southwestern Arkansas, you will typically see the wave clouds develop. And this is, you know, going all the way back to the 80s.

00:29:04:05 – 00:29:14:13
Speaker 3
We’ve seen those. So yeah, question I do have is could you switch over to water vapor. And can we look at a loop of the water vapor imagery.

00:29:14:15 – 00:29:18:10
Speaker 4
Do you want to show that sky or do you want to bring it up okay.

00:29:18:10 – 00:29:25:18
Speaker 1
Yeah I’ll do that.

00:29:25:20 – 00:29:30:07
Speaker 1
And just back off. I mean, let’s to look at here are.

00:29:30:07 – 00:29:32:25
Speaker 3
Some images and you go out and scale.

00:29:32:25 – 00:29:44:15
Speaker 1
A little bit.

00:29:46:18 – 00:29:59:04
Speaker 1
If I can come all the way down.

00:29:59:06 – 00:30:02:21
Unknown
And far. I mean, it’s going up to the west anyway.

00:30:02:21 – 00:30:30:14
Speaker 3
It looks like, you know, you that there is a, jet stream developing over the four corners. You can see the darkening of the water vapor imagery immediately to its north over, southeastern Utah. This jet stream may if it is, there may play a role in, convective initiation later on this afternoon.

00:30:30:17 – 00:30:33:01
Speaker 1
Okay.

00:30:33:03 – 00:30:45:26
Speaker 1
Yeah, that’s an excellent, excellent, situation. And let’s think it’s heading. Yeah. You can see the you can see,

00:30:46:09 – 00:31:10:21
Speaker 3
Maybe, you know, serious equatorial word of the jet and, with some, instability fans theory in. But, as a jet strengthens and then moves, east, you know, it could prove to be interesting, once it encounters, the EML.

00:31:10:24 – 00:31:27:12
Speaker 1
It’ll be interesting to see if it gets there before sunset or if this is just going to be forcing some nocturnal stuff. The timing.

00:31:27:15 – 00:31:33:22
Speaker 4
Okay. Any other questions or comments?

00:31:33:25 – 00:32:03:19
Speaker 4
Okay. Well, thank you everybody for attending. And just a reminder, whenever you have, question, you know, satellite interpretation type of question or whatever, don’t hesitate to email us. And, we’ll answer your question and maybe put a blog together, related to it as well. And, and, that’s one of the purposes of these, satellite chats and try to center them around these times where we’ve had recent events or maybe, real time, interesting real time weather occurring to get these, questions and discussion going.

00:32:03:27 – 00:32:05:22
Speaker 4
Thank you very much and have a great day.

00:32:05:24 – 00:32:06:12
Speaker 1
Thanks, Sam.
