Subj : DAY2SVR: Nws Storm Prediction Center Norman Ok To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Sat Mar 02 2024 06:55:32 ACUS02 KWNS 020655 SWODY2 SPC AC 020654 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1254 AM CST Sat Mar 02 2024 Valid 031200Z - 041200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Severe thunderstorms are not expected on Sunday. ....Synopsis... A potent shortwave trough will lift northeastward through parts of the northern Plains into the Upper Great Lakes on Sunday into early Monday morning. Broad troughing will remain in the West with a southern stream perturbation approaching central/southeast Texas late in the period. At the surface, a deep surface low will also quickly lift northward through the eastern Dakotas and Minnesota. A secondary surface low will form in eastern Colorado during the afternoon and shift into Kansas/Oklahoma during the evening. Very cold temperatures (less than -30 C) aloft in the Pacific Northwest/northern California will support thunderstorm activity primarily along/near the coast. Some activity could extend into the Willamette Valley. Despite cool temperatures/cloud cover, very little heating would be required to support deep enough updrafts for isolated lightning flashes. Late in the period, low-level warm advection in portions of the mid-Missouri Valley region may support the development of elevated buoyancy. Isolated thunderstorms would be possible should sufficient destabilization occur. In the Southeast, a weak upper-level trough should allow for thunderstorm activity along/near a stationary surface boundary as well as along the sea breeze in the Florida Peninsula. A subtle shortwave trough approaching parts of central/southeast Texas coupled with low-level theta-e advection will encourage some destabilization during the evening. Given a pronounced layer of warm air aloft, it appears that thunderstorms will most likely not develop until later in the day on Monday. ...Wendt.. 03/02/2024 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
