DISCUSSION

Issued at 1237 AM CDT Mon May 4 2026

Temperatures will start to increase today through Wednesday with increasing clouds and a moderate risk of heat-related impacts Tuesday and Wednesday across most of South Texas.

A low (~20%)chance of rain return to the Victoria Crossroads Wednesday as a dryline/surface low moves across the area. The rain chances will increase to low to medium (25-45%) chances by Thursday as cold front sags through the area. Rain chances will continue into the weekend with a warm front lifting north Friday and an upper level low moving toward South Texas.

Temperatures are a little tricky behind this cold front because it is entirely possible the front will wash out before it actually gets here, though guidance has been fairly consistent. With medium confidence, we'll expect cooler temperatures Thursday with a gradual warm-up through the weekend.

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

(06Z TAFS) Issued at 1237 AM CDT Mon May 4 2026

VFR conditions are to be expected through the entirety of the period. A short period of MVFR CIGs will be possible at the LRD terminal around 15-17Z, though confidence is low at this time for this. Accounted for this with a tempo at this time. Winds will be out of the southeast through the period around 10-15 knots. Gusts will be around 20-25 knots beginning in the afternoon period across most if not all sites.

MARINE

Issued at 1237 AM CDT Mon May 4 2026

A gentle to moderate (BF 3-4) onshore breeze will increase to a moderate to fresh (BF 4-5) breeze through the middle of the week. Winds will shift briefly to the northeast late Thursday through Friday night as a cold front moves across the area before returning to the southeast Saturday. A low to medium chance of showers and thunderstorms will return Wednesday and continue through the weekend.

FIRE WEATHER

Issued at 1237 AM CDT Mon May 4 2026

Relative humidity values will generally remain at or above 35% through the forecast period. This, combined with winds generally less than 20 mph and ERC in the 0-40 percentile, will prevent fire weather concerns. Low to medium rain chances return Wednesday and continue through the weekend.
