Updated at 621 PM CDT Mon May 4 2026 - Moderate to major risk of heat related impacts Tuesday. - Low to medium chance of showers and thunderstorms return mid week. - Cold front expected Thursday. - Minor coastal flooding and moderate to high risk of rip currents possible Thursday-Friday. && .DISCUSSION... Issued at 145 PM CDT Mon May 4 2026 Mostly cloudy skies and slightly warmer temperatures tonight. A moderate risk (a few locations at a major risk) of heat related impacts Tuesday. The heat risk will generally be across most of S TX, except the Victoria Crossroads. Rain chances return to the Victoria Crossroads by Wednesday when a surface trough/dryline develops across S TX and combines with an embedded mid level short wave. A capping inversion will inhibit convective develop farther south and west. A cold front is expected to move through S TX Thursday morning, bringing a 30-40% chance of showers and thunderstorms across all of S TX. The capping inversion is progged to decrease and the front looks to coincide with another embedded short wave aloft. Rain chances continue behind the cold front through Friday due to the tail end of the mid/upper level trough cuts off over Mexico. The GFS is more aggressive with this feature which would keep low to medium rain chances through Saturday. For now, the other models forecast a weakening upper trough tracking north of S TX with low rain chances for S TX. Behind the cold front, cooler temperatures will filter into the area Thursday and continue through Friday. Northeasterly winds shift to the east and southeast Friday and usher warmer temperatures back across S TX. Minor coastal flooding and moderate to high rip current risk is possible Thursday and Friday due to a moderate northeast flow developing across the western gulf behind the cold front along with increasing seas and swells. && .AVIATION... (00Z TAFS) Issued at 621 PM CDT Mon May 4 2026 Gusty winds at eastern sites will subside over the next couple of hours with VFR CIGS eventually giving way to MVFR. The onset of MVFR looks like it could be a bit later than seasonal timing, being after 09Z for most sites. VFR conditions return during the day on Tuesday. Southeast winds increase in the afternoon for eastern sites with gusts around 25kt, possibly higher by mid to late afternoon. && .MARINE... Issued at 145 PM CDT Mon May 4 2026 A moderate to fresh (BF 4-5) southeast breeze expected tonight. A fresh (BF 5) onshore flow is expected to develop through this evening and continue through Tuesday. Winds may briefly reach advisory levels Tuesday afternoon for the bays and nearshore waters south of Port Aransas. The chance for showers and thunderstorms returns the latter part of the week in response to an approaching cold front. A moderate to fresh (BF 4-5) northeast flow is expected to develop behind the cold front Thursday. Winds decrease and shift to the east-southeast Friday. && .FIRE WEATHER... Issued at 145 PM CDT Mon May 4 2026 Relative humidity values will generally remain at or above 35% through the forecast period. This, combined with sustained 20 foot winds less than 20 mph and ERC in the 0-40 percentile will prevent fire weather concerns. Wetting rains expected to return the latter half of the week in response to an approaching cold front. && .PRELIMINARY POINT TEMPS/POPS...
