348 ACUS03 KWNS 021903 SWODY3 SPC AC 021902 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0102 PM CST Tue Dec 02 2025 Valid 041200Z - 051200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated to scattered thunderstorms are possible on Thursday across coastal portions of the western and central Gulf Coast vicinity. Severe potential appears low at this time. ...Western and Center Gulf Coast vicinity... Broad upper troughing will envelop much of the CONUS on Thursday. Strong surface high pressure will be in place over the Rockies/Great Basin, as well as across the Midwest. Meanwhile, a cold front will be draped along/just offshore the TX coast, while a warm front extends eastward near the LA coast, then southeast across the eastern Gulf. As an upper shortwave trough moves across the Plains, a weak coastal low will develop along the Upper TX Coast/LA coast late in the period. This may allow richer Gulf moisture to move into far southeast LA and coastal MS/AL in the 09-12z time period. Midlevel warm advection and increasing ascent atop a cool boundary layer will support elevated thunderstorm activity along portions of the western/central Gulf coast through the period. While some surface-based instability could move inland very late in the period, this is uncertain and may remain over immediate coastal areas of southeast LA. Overall, severe potential is expected to remain limited given Gulf moisture will mostly remain offshore through the period, though trends will be monitored for some increasing potential late in the Day 3 (early Friday morning) time frame. ..Leitman.. 12/02/2025 $$
