Subj : DAY1SVR: Day 1 Convective Outlook To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Tue Jan 02 2024 19:25:05 ACUS01 KWNS 021925 SWODY1 SPC AC 021923 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0123 PM CST Tue Jan 02 2024 Valid 022000Z - 031200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Scattered thunderstorms are expected in central Texas through this evening, and into southeast Texas and southern Louisiana tonight. Isolated thunderstorms will be possible this evening through tonight along the northern/central California coast. ....Discussion... Previous forecast reasoning remains valid. Western portion of TX thunder line has been tweaked based on latest observations. ...Grams.. 01/02/2024 ..PREV DISCUSSION... /ISSUED 1015 AM CST Tue Jan 02 2024/ ....Synopsis... Within a southern stream, one shortwave trough will progress eastward from far west TX to the northwest Gulf coast by early Wednesday, as an upstream trough moves over CA. A modifying air mass is returning northward across the western Gulf of Mexico, though weak cyclogenesis across the shelf waters will keep the surface warm sector just offshore of all but the immediate lower TX coast. There will be some potential for a supercell or two over the near-shore waters of the middle/upper TX coast, but convection will subsequently move farther offshore, which suggests that any severe threat over land is too low to add any probabilities. Scattered/elevated thunderstorms will form farther inland in a zone of increasing ascent over central TX this afternoon, and storms will continue through tonight into southeast TX and southern LA. Otherwise, isolated thunderstorms will be possible later today into tonight across the northern/central CA coast as the upstream trough/midlevel cooling and steepening low-midlevel lapse rates spread inland. $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
