DISCUSSION

Issued at 1013 PM CDT Mon Apr 13 2026

High pressure over the Gulf into the southeastern US will maintain warm, breezy, and dry conditions through the week. Temperatures will continue to warm, reaching the 90s for much of the region by Thursday. Coastal areas will remain in the upper 70s into the 80s.

As we head into the weekend a cold front will move through Texas bringing with it another chance of rain and thunderstorms Saturday afternoon through Monday. The aforementioned front will move through Deep South Texas on Sunday which will also be the day for our highest rain chances (35-50%). Cooler temperatures are expected in wake of the front, with highs in the mid 70s to mid 80s on Sunday and mid 80s on Monday.

AVIATION

(12Z TAFS) Issued at 612 AM CDT Tue Apr 14 2026

A mixture of VFR to MVFR ceilings are expected for the TAF period. While some MVFR ceilings are expected for the next couple of hours, as the southeasterly winds pick up, so should the ceilings as well. This will allow for generally VFR conditions to take over for the rest of the daytime hours. As mentioned before, the southeasterly winds could gust up to 30 knots today. Winds should weaken again tonight.

MARINE

Issued at 1013 PM CDT Mon Apr 13 2026

Generally favorable marine conditions are expected on the waters off the lower Texas coast with moderate winds and wave heights. Could see some caution conditions each afternoon, mainly on the Laguna Madre and nearshore waters due to a locally enhanced pressure gradient.
