(Today through Friday) Issued at 1212 AM CST Thu Dec 11 2025 An upper level ridge over the west coast is producing northwesterly flow over Texas this morning. A cold front has moved to the coast. The pressure gradient has loosened and the northerly winds have become light across South-Central Texas. Drier air has moved in with dewpoint temperatures 10-15 degrees lower than 24 hours ago. The surface high will move to the east today turning the low level flow to the east and high temperatures will yo-yo down today to the 60s and lower 70s. As the high moves farther east winds will shift around to the southeast and south. The yo-yo will swing back up with lows Friday about five degrees warmer than today and highs around 10 degrees warmer reaching the middle to upper 70s. && .LONG TERM... (Friday night through Wednesday) Issued at 1212 AM CST Thu Dec 11 2025 Southerly flow in the low level will continue Friday night and lows Saturday will be warmer again. Saturday will start cloudy over the eastern half of the area and this will result in high temperatures being a couple of degrees lower than Friday. Sunday another cold front will will move through and there may be enough moisture in the Rio Grande region to generate some showers or even a thunderstorm, but chances are only 20%-40% during the day. There will be breezy northeasterly winds behind the front Sunday afternoon. Temperatures will be cooler again Sunday and Monday. Tuesday an upper level shortwave trough will move over the region. Today the blended model is dry as this feature passes. However, the GFS generates showers Tuesday and Wednesday. We will have to wait for further guidance to see which solution pans out. Rain or no rain, temperatures will warm over the last couple of days of the forecast. && .AVIATION... (06Z TAFS) Issued at 1212 AM CST Thu Dec 11 2025 VFR flight conditions prevail.
