Thunderstorms are still forecast across portions of southern Louisiana and immediate surrounding areas on Sunday. No severe weather is expected. ...Synopsis... A split upper-flow regime will overspread the CONUS on Sunday, with a pronounced mid-level trough poised to traverse the U.S./Canada border as a smaller mid-level impulse progresses along the Gulf Coast. A statically stable airmass will be in place over most of the CONUS, limiting thunderstorm development over most locales. Scant elevated buoyancy will accompany the Gulf Coast trough, mainly over southern LA and immediate surrounding areas. Isolated to potentially scattered thunderstorms are expected to be in progress at the start of the period (12Z Sunday), and may continue into the afternoon, until the elevated buoyancy is shunted offshore. ..Squitieri.. 02/21/2025 $$
