Using synthetic WRF imagery for low cloud forecasts

Posted On: January 19, 2011 - By: Dan Lindsey

On the morning of 19 Jan. 2011, a nice example of using the simulated WRF imagery to forecast low clouds presented itself.  The image on the right is the 17-hour forecast from the 00Z WRF run, and low clouds are evident in the Arkansas River Valley in southeast Colorado, as denoted with the arrow.  The left image is the corresponding GOES-13 IR image at 17 UTC, showing that these clouds were indeed observed.  A forecaster might then look at the forecast images over the next several hours to see whether the model dissipates the clouds.
