-Rain chances return late in the week with the next front

DISCUSSION

Issued at 128 AM CDT Sun Apr 26 2026

The forecast looks to remain mostly through majority of the upcoming work week. The main story will be above normal temperatures and moderate to major heat stress conditions beginning today lasting through latter portions of the week. This will be due 850 mb temps around 23-27 degrees C, which translates to the 90th to climatological max for this time of year. This will lead to very warm temperatures across South Texas and high heat indices around 105-110 degrees through at least Tuesday and 100-105 degree Wednesday and Thursday. This may necessitate the issuance of heat products and which we will continue to monitor. Regardless the practice of heat safety is strongly encouraged. Take frequent breaks and remember to stay hydrated, check those backseats, and avoid long exposure in these temperatures. For more information be sure to check out weather.gov/heatsafety.

Around Friday/Saturday, our next front is expected to arrive. This will be a brief cool down from above normal temperatures down to around normal. Highs are forecasted to be in the 70s and 80s across much of the area through the weekend. Currently low rain chances also return with this front though with this being far out things could definitely change between now and then.

AVIATION

(06Z TAFS) Issued at 128 AM CDT Sun Apr 26 2026

MVFR to IFR CIGS are expected through the night, similar to last night. Will see an improvement by late morning Sunday with VFR conditions persisting through the daytime hours. Expect CIGS to decreasing again at eastern sites before the end of the period.

MARINE

Issued at 128 AM CDT Sun Apr 26 2026

A gentle to moderate onshore flow (BF 3-4) is expected to become a fresh breeze (BF 5) Thursday ahead of an approaching cold front next weekend, returning low rain chances of 20-30%.

FIRE WEATHER

Issued at 128 AM CDT Sun Apr 26 2026

Elevated fire weather conditions will not be expected through next weekend. Minimum relative humidity will drop as low as 25-35 percent over the Brush Country each afternoon, but winds will likely remain below elevated criteria. Temperatures will heat up next week with highs in the triple digits over the Brush Country through Wednesday before a cold front approaches South Texas late in the week. The cold front will then push through next weekend, leading to low rain chances, increased cloud cover, and a decrease in temperatures.
