Issued at 1207pm CST Sunday Nov 9 2025

Conditions are developing as expected following this morning's cold front. Critical fire weather conditions are in play, strong north to northeasterly winds of 15-25 mph with gusts up to 35 mph and relative humidity has dropped to 15-30% across South Texas. A Red Flag Warning remains in effect through 9pm tonight. Although winds diminish tomorrow, elevated fire weather conditions will be in place and a Fire Danger Statement has been issued for all of South Texas from 9am to 9 PM.

Lows tonight will drop into 40s, with a few localized area in our northern counties dropping into the upper 30s. Early Tuesday morning is looking to be our coldest of the season so far, light winds and clear skies will set the stage for efficient radiational cooling. There is a medium to high (40-80%) chance for lows dropping into the 30s over our northern counties, stretching from La Salle to Victoria counties. In fact, the NBM has a low (10-30%) chance of brief freezing temperatures in cold drainage areas stretching across McMullen County to Goliad County.

Onshore flow returns Tuesday, returning a warming trend heading into the upcoming weekend, with highs back well into the 80s by Wednesday and lows in the 60s. The next cold front looks to arrive Saturday or Sunday, bringing our only mentionable low chances for showers and thunderstorms, mainly over the Victoria Crossroads.
