(Tonight through Sunday night) Issued at 109 PM CST Sat Dec 6 2025 Dry and warm conditions are ongoing across South Central Texas early this afternoon. Today`s highs are projected to reach the mid to upper 70s. Low clouds are forecast to develop across the Coastal Plains and spread to the north into the I-35 Corridor overnight through Sunday morning. During that same time period, patchy to areas of fog are forecast to develop across the Coastal Plains and portions of the I-35 Corridor. While this is happening with the fog across the Coastal Plains, a Pacific front is pushing down across the Rio Grande and Southern Edwards Plateau. The frontal passage is likely to move across the I-35 Corridor between 830 AM and 930 AM Sunday and should be exiting the southern part of the local area by noon. In the wake of the frontal passage, moderate northerly winds of 10 to 20 mph and gusts of 25 to 30 mph are forecast for most of the day time period. A cooler airmass also follows the front with forecast high temperatures in the 60s for the Hill Country and Southern Edwards Plateau with the rest of the area in the mid to upper 70s. Overnight lows are forecast to be colder than previous mornings with lower 30s over portions of the Hill Country and Southern Edwards Plateau and upper 30s to lower 40s elsewhere. && .LONG TERM... (Monday through next Saturday) Issued at 109 PM CST Sat Dec 6 2025 Dry with a warming trend for most of the work week with the exception of Friday as a cold front moves across the local area late Thursday night through early Friday morning. Next weekend looks dry and cool. && .AVIATION... (18Z TAFS) Issued at 109 PM CST Sat Dec 6 2025 VFR conditions are expected through tonight under clear skies with west to southwesterly winds under 10 knots. Low clouds and fog are favored east of I-35 terminals early Sunday morning ahead of a cold front; however, recent guidance has developed low visibility and ceilings further west. Due to this uncertainty, have opted for TEMPO groups at I-35 terminals for MVFR to IFR visby/ceilings, though if trends continue to show this fog further west, conditions may drop as low as LIFR. The cold front moves across the area Sunday morning with gusty northerly winds for the afternoon behind this feature. && .PRELIMINARY POINT TEMPS/POPS...
