(Tonight through Saturday) Issued at 1152 PM CST Thu Dec 11 2025 Cold front will move into the Big Country mid to late morning, moving along a Mertzon to San Angelo to Brownwood line around 1 PM, and along I-10, 6 to 7 PM. Main cold advection today will be in the Big Country with highs in the mid and upper 60s, with highs in the 70s to the south. Gusts of 17 to 22 mph are possible behind the front, mainly along and north of I-20. Air behind the front will be mainly dry, but late tonight, low level moisture and clouds may return in southeastern sections from Junction to Brady, as a warm front returns. Lows tonight will range from the mid 30s in the Big Country to lower to mid 40s along I-10 and portions of the Heartland. && .LONG TERM... (Saturday night through next Friday) Issued at 1152 PM CST Thu Dec 11 2025 A broad area of low pressure across the Midwest will send a strong cold front through our area late Saturday night into Sunday morning. This will usher in much colder conditions across the Big Country for Sunday morning. Much of the model guidance depicts low temperatures in the middle 20s to 32 degrees. Strong northerly winds behind the frontal boundary could be sustained in the 15 to 20 MPH range. This will create wind chill (what it actually feels like) readings down into the teens. Afternoon highs on Sunday will be much cooler area wide with most models forecasting highs between 43 and 47 degrees. Sunday night will also be cold with most locations sitting in the upper 20s to near freezing. Afterwards, a minor upper level disturbance is shown moving across Texas. However, any precipitation will be off to the south and southeast of our area. Some lingering cloud cover will be the only change this system will bring. Otherwise, expect temperatures to quickly warm back up through the remainder of the work week. && .AVIATION... (18Z TAFS) Issued at 1134 AM CST Fri Dec 12 2025 A weak cold front along the I-20 corridor will move south across the rest of the area this afternoon and early evening. North to northeast winds will follow its passage, and then winds will become light late tonight into Saturday morning. VFR conditions and clear skies will occur this afternoon through early tonight. Low cloud development is expected late tonight over the southeastern part of our area, with northward expansion into the morning Saturday. Expect mostly MVFR ceilings at KBBD, KJCT and KSOA, but IFR ceilings should affect KSOA by mid-morning. Patchy development of clouds is also anticipated as far north and west as KABI and KSJT Saturday morning. && .PRELIMINARY POINT TEMPS/POPS...
