Updated at 602 PM CDT Fri Jul 18 2025 - Moderate heat risk across most of South Texas with portions of the Brush Country in major through next week. - Daily afternoon borderline elevated fire weather conditions across portions of the Rio Grande Plains Sunday through Wednesday. && .DISCUSSION... Issued at 1248 PM CDT Fri Jul 18 2025 Remnants of Invest-93L remains focused over Southeast Texas, keeping mainly rain-free conditions intact across South Texas on the western side this afternoon. There is above normal moisture (GOES indicating PWATs nearing 2.0") across the Victoria Crossroads that still warrants a low chance for showers and thunderstorms. Surface high pressure and mid-level ridging over the eastern Gulf will shift westward into the middle of next week, keeping generally rain-free conditions in place and normal to above normal temperatures. Daily max heat indices will likely range from 105-110 with little recovery, causing a moderate risk of heat-related impacts across most of South Texas with a few areas in the Brush Country in a major risk. Looking towards the end of the forecast and work week, a weak surface low is hinted at developing over the northeastern Gulf associated with a stationary front, then shift westward towards the Texas Coast. Therefore, additional lift and enhanced moisture will return our next low rain chances Friday. Lastly, borderline elevated fire weather conditions will be present over portions of the Rio Grande Plains in Webb County each afternoon and early evening Sunday through Wednesday due to winds around 20 mph and relative humidity dropping to 25-30%. && .AVIATION...
