| Area Forecast Discussion National Weather Service Brownsville TX 1046pm CST Tuesday Jan 6 2026 Issued at 1028pm CST Tuesday Jan 6 2026 Another round of fog is expected overnight due to elevated moisture content and low winds. Model guidance is not as favorable tonight for fog development as last night with NBM probability of generally 20 to 40% that visibility will fall below 5 miles. Will continue to see dry conditions and well above normal temperatures across the region through Friday. Wednesday night, an upper level trough will swing through the SW and northern Mexico with low pressure developing over the Rockies. This will increase the pressure gradient across the region leading to breezy conditions, especially along the coast Wednesday night into Thursday as the trough pushes eastward. An associated cold front will move through the region on Friday with winds breezy conditions in its wake Saturday into Sunday. Cooler air will filter in behind the front and temperatures will fall below seasonal norms for the weekend. There is a low chance of precipitation, around 20-30%, Saturday and Sunday. Even with rain chances in the forecast elevated winds and continued abnormally dry conditions will lead to the potential for a Fire Danger Statement on Saturday. Will continue to monitor for this potential. Marine Issued at 1028pm CST Tuesday Jan 6 2026 Generally favorable marine conditions begin to deteriorate ahead of a frontal boundary by Wednesday afternoon with Small Craft Exercise Caution needed on the waters off the lower Texas coast. Small Craft Advisories will be needed Wednesday night into Thursday as the pressure gradient continues to tighten, and again Friday night into Sunday in response to strong winds and elevated seas in wake of a cold front passage on Friday. Low to medium rain chances return this weekend. NOAA Brownsville TX Office: Watches - Warnings - Advisories TX...None. GM...None. |
