Updated at 147 PM CDT Sun Mar 29 2026

DISCUSSION

Issued at 147 PM CDT Sun Mar 29 2026

Deeper moisture will return to South Texas with PWATs increasing to 1.5-1.6 inches by the end of the week. A cold front is expected to approach the area by the middle of the week, but guidance is still unclear as to how far south this front will push south before it washes out. The GFS continues to be a bit more aggressive, bringing it through South Texas while all other guidance keeps it to the north. This does make the rain forecast a bit tricky. Current thinking is that deeper moisture, a shortwave moving over the area, and weak instability will lead to low (15-25%) chances for showers and thunderstorms Wednesday into Thursday. Should the front actually make it into the area, chances could increase to a more medium chance with the increased lift. Regardless of the potential front, above normal temperatures will continue through the upcoming week.

AVIATION

(18Z TAFS) Issued at 147 PM CDT Sun Mar 29 2026

Southeasterly winds will strengthen through the afternoon to around 15 knots sustained with gusts 20-25 knots, particularly over the Coastal Plains. Winds diminish tonight with additional MVFR/IFR ceilings and vsby expected after 06Z before conditions return to MVFR around 15Z Monday.

MARINE

Issued at 147 PM CDT Sun Mar 29 2026

A gentle to moderate (BF 3-4) southeasterly flow will continue through the week. Periods of a fresh (BF 5) breeze south of Port Aransas to Baffin Bay will be possible Wednesday night through the end of the work week. There is a low (10-25%) chance of showers and thunderstorms by the middle of the week.

FIRE WEATHER

Issued at 147 PM CDT Sun Mar 29 2026

Minimum relative humidity values are expected to drop below 30% each afternoon over the Rio Grande Plains and Brush Country this week. When combined with breezy southeasterly flow and dry fuels, this may lead to elevated to near critical fire weather conditions at times during the week, mainly across the Brush Country and Rio Grande Plains. A low chance of showers and thunderstorms will return by the middle of the week, which could help to improve fire weather conditions.
