1128pm CST Wednesday Jan 7 2026

Issued at 1120pm CST Wednesday Jan 7 2026

The warm trend is expected to continue through Friday yielding well above normal temperatures (15+ degrees above normal) before our next cold front pushes through Friday night, ushering in cooler weather and finally bringing back below normal temperatures. This stretch of colder weather is expected to continue through early next week before we warm back to near normal temperatures by mid-week. Rain chances with this front will be limited with the best chances coming across the Victoria Crossroads (25-45% chance). With isentropic lift setting up in the wake of the front, low rain chances will remain in the forecast from Friday night through Saturday night across the Coastal Bend (20-25% chance).

A fresh to strong breeze (BF 5-6)is expected to continue through Thursday with winds briefly weaken Thursday night ahead of our next cold front. A fresh to strong (BF 5-6) northerly breeze is expected Friday night through Sunday in the wake of the front. Rain chances will increase to low to medium levels (30-55%) Friday through Saturday as the front pushes through the region.

Fire Weather
Issued at 1120pm CST Wednesday Jan 7 2026

Drier air will filter back into the region with minimum relative humidity values dropping below critical levels as low as 20-30% Saturday and Monday and relative humidity values dropping into the 10-25% range Sunday across most of South Texas. The strongest wind can be expected Saturday with sustained winds between 15-20 mph and gusts to 25 mph or slightly higher. Winds Sunday and Monday will be relatively light with winds less than 15 mph. Energy Release Component (ERC) values Saturday will range from the 60-65th percentile and increase to the 70-80th percentile Sunday across the Coastal Plains. With the low relative humidity values, stronger winds and higher ERC values, expected fire weather conditons are trending higher compared to yesterday, with elevated fire weather now expected this weekend with a chance of seeing critical fire weather conditions.
