Subj : DAY1SVR: Day 1 Convective Outlook To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Thu Dec 21 2023 05:51:13 ACUS01 KWNS 210550 SWODY1 SPC AC 210548 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1148 PM CST Wed Dec 20 2023 Valid 211200Z - 221200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Isolated thunderstorms are possible across parts of central/southern California and southern Arizona. Severe thunderstorms are not expected. ....Synopsis... A deep-layer cyclone is forecast to move slowly southeastward off of the southern CA and Baja California coast during the day, before potentially accelerating eastward late in the period. Based on the trajectory of this system, most thunderstorm activity will likely remain offshore through the day, though isolated thunderstorms will be possible across coastal regions of southern California. With inland destabilization forecast to remain quite weak and stronger deep-layer flow/shear expected to remain offshore, severe-thunderstorm potential appears limited, though a strong storm or two cannot be ruled out across the Channel Islands and immediate coastline. Overnight, some threat for isolated thunderstorms may spread across interior southern CA into southern AZ, as the low begins to move eastward. ...Dean/Squitieri.. 12/21/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
