(Tonight through Tuesday night) Issued at 1110 PM CST Sun Nov 30 2025 Infrared satellite pictures reveal eastern Pacific moisture arriving across the local area while area Doppler radars are picking up light rain echoes. When looking at the 00Z Del Rio sounding, from the surface to about 3000 ft, the atmosphere is dry with a saturated layer above it and a second saturated layer around and above 15,000 ft. Therefore, those light rain echoes are not reaching the ground. As the overnight progresses, the low level layer is forecast to moisten enough for the developing of light rain/drizzle across the I-35 Corridor and Coastal Plains by dawn. A surface low to the east of Brownsville is forecast to push to the northeast while staying over the Gulf waters but getting close to the middle and southern Texas coast throughout the day Monday to keep moderate rain chances especially along the I-35 Corridor and better chances for the Coastal Plains. Rainfall amounts are likely to be limited to a few hundredths to half inch with a few spots across the Coastal Plains (Lavaca County and nearby locations) that could get up to 2 inches. Cloudy skies are forecast through the morning period area-wide, however, drying taking place at mid to upper levels to mix down to help breaking the clouds for partly cloudy skies across the Rio Grande and Southern Edwards Plateau. Unfortunately, the high moisture content stays along the I-35 Corridor and Coastal Plains for cloudy skies all day and cooler temperatures in the 50s while the Rio Grande could get into the upper 50s and lower 60s range. By Monday evening, the rain chances shift to the east as the Gulf low pressure system moves to the northeast into the north central part of the Gulf and a northwest to zonal flow establishes over South Central Texas. Clearing/partly cloudy conditions likely to take place over most areas across South Central Texas overnight/early Tuesday morning resulting in a cold night with lows in the 30s across the Southern Edwards Plateau, Hill Country, parts of the I-35 Corridor, and Coastal Plains. A light freeze is forecast for some locations across the Hill Country. After a cold start of the day, temperatures are rising to the upper 50s and lower 60s under mostly sunny to partly cloudy skies. && .LONG TERM... (Wednesday through next Monday) Issued at 1110 PM CST Sun Nov 30 2025 A warming trend is in store for Wednesday with highs forecast to reach the mid to upper 60s and even lower 70s over the southern portion of the Rio Grande under cloudy skies. By Wednesday evening, an upper level short wave over the Four Corners region is forecast to move to the east-southeast and over the Southern Plains through Thursday evening and a second disturbance later on during the overnight hours. At the surface, a cold front is forecast to push across the local area from northwest to southeast through the time frame for moderate to high chances of rain. Moderate rain chances are still in the forecast for midday Friday as several perturbations move over the local area with a southwest flow aloft. By Friday afternoon into the evening, dry conditions take place and spreads over the weekend with a warming trend expected and highs rising to the 70s. && .AVIATION... (06Z TAFS) Issued at 1230 AM CST Mon Dec 1 2025 MVFR cigs will continue this morning, with bases expected to drop 2K AGL along I-35 after 10Z. We should also see some light rain develop, but do not expect any significant reduction in the visibility. MVFR cigs remain intact through most of the day, with cigs rising back above 2K AGL around 20Z, with VFR returning between 22-23Z. For DRT, some MVFR cigs are expected to develop around 09Z, then back to VFR around 14Z. Some drier air in the lower levels should then lead to only high clouds after 18Z. && .PRELIMINARY POINT TEMPS/POPS...
