KEY MESSAGES
Updated at 606 PM CDT Tue Apr 14 2026
Key Messages:
- Breezy conditions will continue this week.
- A moderate risk of rip currents will likely prevail through the week.
- Temperatures above average through this week with a cool down late this weekend.
- Unsettled weather will return this weekend in association with a cold front moving through Texas.
DISCUSSION
Issued at 127 PM CDT Tue Apr 14 2026
High pressure over the Gulf will maintain warm, dry, and breezy weather through the remainder of this week. Above average temperatures with highs around 90 (80s near the coast) and morning lows in the low 70s will continue through Saturday. Breezy southeasterly winds will continue, with gusts of 30-35 mph possible each afternoon, with the breeziest afternoon being Friday. These should stay below Wind Advisory criteria, but Friday in particular will continue to be monitored. Rain chances are 10% or less through Saturday.
At local beaches, there is a Moderate Risk of Rip Currents through at least Wednesday. Gusty winds in conjunction with Friday's new moon will likely keep the risk elevated through the week.
Persistent southeasterly flow will allow moisture to build into this weekend. Ensemble PWAT values are forecasted to be greater than the 90th percentile of climatological normals (1.7- 1.9"). A cold front expected to sweep through deep South Texas late Saturday into Sunday will bring cooler temperatures and be able to tap into this moisture, increasing rain chances Saturday night through Monday. The greatest chance of rain at this time is Sunday, with moderate chances (40-60%) region wide. Check back for updates as we continue to refine the forecast.

This weekend, Small Craft Advisory conditions are possible behind a cold front with rough seas Sunday into Monday.
There is an increased chance of rain and thunderstorms Saturday night through Monday.
