| Area Forecast Discussion National Weather Service Brownsville TX 1028pm CST Monday Dec 15 2025 Issued at 1026pm CST Monday Dec 15 2025 A shortwave trough swings across northeastern Mexico into late week, increasing moisture and instability across Deep South Texas mid to late week. The subtropical ridge returns this weekend with drier air. At the surface, the frontal boundary gradually lifts north into the CWA (County Warning Area) through Wednesday with a coastal trough of low pressure, increasing the chance of showers and thunderstorms Tuesday night into Wednesday night. The front eventually pulls southeast into late Thursday or early Friday with a brief northerly wind shift. Expect a gradual warming trend from slightly above normal to well above normal temperatures through the forecast period, with a briefly cooler but comfortable day on Friday. A moderate risk of rip currents continues Tuesday and may persist through the week due to a long period swell across the western Gulf. Marine Issued at 1026pm CST Monday Dec 15 2025 Marine conditions generally improve through the forecast period, with an increasing chance of showers and thunderstorms Tuesday night into Wednesday and a brief northerly wind shift behind a front on Friday. Expect southeasterly onshore flow through most of the period aside from Friday. NOAA Brownsville TX Office: Watches - Warnings - Advisories TX...None. GM...None. |
