- Marginal threat (1 out of 5) for severe storms today.

DISCUSSION

Issued at 102 AM CDT Thu Apr 30 2026

After another day of warm temperatures today, the cold front to our north will finally begin a push across South Texas late Thursday night into Friday, bringing us a medium to high (40-90%) chance of showers and thunderstorms. A few of these storms could be strong to severe, so SPC has included the northern portions of our area in a Marginal Risk of severe thunderstorms late Thursday night/early Friday morning through Friday night. With PWAT values of 1.6-1.8", heavy rainfall and high rainfall rates are also expected so WPC has the Victoria Crossroads and northern Coastal Plains in a Slight Risk of excessive rainfall with the northern Brush Country in a marginal risk of excessive rainfall for Friday, so we'll need to monitor for some localized flash flooding. For today through Saturday, rainfall totals could range from 0.25"-around 1". Storm totals in the portions of our watershed that are to our north are also going to see some rain with totals 1-1.3".

Chances for precipitation diminish early Saturday, leaving us with cooler temperatures (highs in the 70s!) and dry conditions.

AVIATION

(12Z TAFS) Issued at 619 AM CDT Thu Apr 30 2026

Most sites are once again seeing mainly MVFR CIGS this morning, though CRP has broken out to VFR at least briefly. VCT is holding at IFR early this morning, but should improve with all other sites by mid to late morning. VFR conditions are expected through the afternoon. Tonight expect low CIGS to develop once again. We will also start to see convection move across the area from northwest to southeast. Have a mention in all TAFS except CRP which would likely be a bit after the end of this period.

MARINE

Issued at 102 AM CDT Thu Apr 30 2026

A gentle to moderate onshore flow (BF 3-4) will continue through Friday ahead of a cold front. Winds will increase slightly to a more moderate flow Friday before shifting to the northeast and then increasing to strong to near gale (BF 6-7) Friday night through Saturday. Winds will gradually diminish to a moderate to fresh (BF 4- 5) Saturday night through Sunday before further weakening to gentle to moderate and turning east late Sunday then to the southeast Monday. A medium to high (40-75%) chance of showers and thunderstorms will develop as early as Thursday night and continue through Friday night.

FIRE WEATHER

Issued at 102 AM CDT Thu Apr 30 2026

Relative humidity values will remain at or above 35% through the forecast period. This, combined with medium to high rain chances Friday, will limit fire weather concerns into early next week.
