| Area Forecast Discussion National Weather Service Brownsville TX Issued by National Weather Service Lake Charles LA 1112am CST Monday Dec 15 2025 Issued at 1100am CST Monday Dec 15 2025 The cold front that brought the cooler temperatures is well into the Gulf, and we are feeling the last of the cold air advection from this front. This evening, winds will shift from the north to the east, then the southeast, as high pressure builds in the Gulf behind the front. With the southeasterly winds will come an increase in dew points as moisture builds across the RGV. Aloft, a trough will dig south into Mexico before lifting north along the coast. This system will cause enough instability to bring scattered showers and isolated thunderstorms to the region. Probability of Precipitation will not be evenly distributed with a low chance (10-30%) for showers on the western side of the CWA (County Warning Area) and a high chance (50-70%) along the coast Wednesday and Wednesday night. Rainfall totals don’t look too impressive with the average amounts around 0.02 inches with even the 90th percentile below 0.10 inches for most of the region. Thursday going into Friday, a dry cold front is expected to move through the region. Rain won’t be a concern with this front, but it will drop our highs back into the 70s with dew points in the 40s and 50s. The cool down will be short-lived as high pressure in the Gulf reasserts itself, and warm air advection brings temperatures 10 to 15 degrees above normal, with highs in the 80s. The rest of the forecast looks to be warm and humid as we head into Christmas week. Marine Issued at 1100am CST Monday Dec 15 2025 Most of the impacts today are on the marine side, even with the decreasing winds and waves. Multiple hazards are in effect both along the coast and offshore. Along the coast, there is a high rip current risk, high surf advisory, and a beach hazard statment until 6pm this evening. Wave heigheights are between 4 and 6 feet and have a swell of 8 seconds, leading to surf heigheights of 7 to 8 feet. Offshore winds are above the 20-knot threshold for a small craft advisory; similar to the coastal hazards, winds will fall below hazardous levels this evening. In the extended forecast, rain chances will return on Wednesday, followed by a weak cold front on Friday. NOAA Brownsville TX Office: Watches - Warnings - Advisories TX...High Rip Current Risk until 6pm CST this evening for TXZ451-454- 455. High Surf Advisory until 6pm CST this evening for TXZ451-454- 455. GM...Small Craft Advisory until 6pm CST this evening for GMZ150-155- 170-175. |
