High cloud obscuration during a lake-effect snow event

When analyzing satellite imagery during lake-effect snow events, one is interested in looking at the low-level clouds associated with the snowbands.  However, sometimes high clouds obscure the low-level clouds making analysis from a satellite imagery perspective more challenging.  An example of high cloud obscuration can be seen in this GOES-16 loop from 2 January 2018: Continue Reading

Advected LPW product in identifying circulations in the vertical

On the evening of 21 February 2017, a well defined mid-level circulation moved into the San Francisco Bay region.  This circulation was responsible for a region of convection in the vicinity, mostly showers but a few thunderstorms with some low-level rotation. The mid-level circulation can be readily identified in the 700-500 mb layer of the Continue Reading
