(Tonight through Wednesday night) Issued at 1135 PM CST Mon Dec 1 2025 Clearing has been taking place at lower levels across most areas this evening with few to scattered high clouds moving from the west arriving from the eastern Pacific. At the surface, a high pressure system is building across the Southern Plains and forecast to push to the east and northeast throughout the day on Tuesday. A light northerly wind flow combined with a cold airmass translates to a cold overnight and early Tuesday morning period with lows forecast to drop to the freezing mark and even lower across some locations over the Hill Country and Southern Edwards Plateau. Freezing temperatures could last for several hours across the Hill Country including the majority of the Burnet and Williamson Counties, where a Freeze Warning is in effect from 3 AM through 8 AM Tuesday. Most areas across the Hill Country and Southern Edwards Plateau are likely to experience wind chill values in the mid to upper 20s and areas along the I-35 corridor and Coastal Plains in the upper 20s to lower 30s. The Rio Grande feel-like temperatures range from the upper 30s to lower 40s late overnight and daybreak time window. After a cold start of the day, temperatures are forecast to come up to the mid and upper 50s and 60s under mostly sunny skies for the most part. Not as a cold night is forecast for late tonight/Wednesday morning period with lows in the mid to upper 30s and 40s. Increased moisture arrives across the local area overnight and continues throughout the day on Wednesday and especially across the Coastal Plains and the I-35 Corridor as a coastal low develops near the middle Texas coast. Rain chances begin over these areas Wednesday afternoon and evening while expanding to the Hill Country late Wednesday night into Thursday as a cold front pushes down through the local area. && .LONG TERM... (Thursday through next Tuesday) Issued at 1135 PM CST Mon Dec 1 2025 The cold front pushes into the Texas coast Thursday morning while rain chances continue across the region with the help of several perturbations within the southwest flow aloft moving over South Central Texas. Then, Thursday evening into Friday morning, an upper level short wave over the Four Corners region pushes into the southeast and over west Texas keeping rain chances over a good portion of the local area, however, favoring the Coastal Plains. Storm totals rainfall forecast range from a few hundredths up to half inch. Can`t rule locations over the Coastal Plains to get higher amounts. Dry weather spreads from west to east on Friday afternoon into the evening and continues into the weekend. Saturday forecast calls for dry weather with highs in the 70s for most places across South Central Texas. A dry cold front is forecast to push over the region on Sunday with highs near to slightly higher than climate normal values for this time of the year. Clear skies and light winds combined with a cold airmass to bring lows into the mid to upper 30s and 40s on Monday morning. Dry conditions and high temperatures above normal values stay through at least mid-week. && .AVIATION...
