.SHORT TERM... (Today and tonight) Issued at 118 AM CDT Sun Sep 14 2025
Early this morning, some lingering showers over the Big Country are continuing to dissipate. Temperatures generally are in the mid 70s with mostly cloudy skies and light southeast winds. Much of west Texas will remain at the south end of a mid-level trough centered over eastern Colorado. Just like yesterday, south to southeast winds at the surface should increase this afternoon with gusts around 20 MPH at times. Similar to yesterday, close to 1000 J/kg of instability is expected to develop this afternoon, mainly west of a line from Throckmorton to Sonora. Given forecast high temperatures in the low 90s with dewpoints in the mid 60s, there is a low chance for showers and thunderstorms over our western counties this afternoon. The aforementioned trough axis is expected to lift northeastward throughout the day today which could provide some dynamic support for any storms that develop So far, high-res models indicate storms will develop over the Permian Basin and move into our western counties late this afternoon and evening before dissipating after sunset. While some showers and/or clouds could linger through part of the night, winds should diminish and allow low temperatures to range from the mid 60s to low 70s.

.LONG TERM... (Monday night through next Sunday) Issued at 123 PM CDT Sun Sep 14 2025
An upper level ridge centered across northern Mexico will result in generally hot and dry conditions across West Central Texas on Tuesday and Wednesday. Highs will be in the upper 80s to lower 90s, with overnight lows in the 60s.
Wednesday night into Thursday, an upper level trough will swing across the Great Plains, weakening the ridge centered over northern Mexico. In addition, a weak cold front will push south into the Big Country Wednesday night into Thursday. The passage of the upper level trough along with the weak cold front in the area will result in isolated to scattered showers and thunderstorms on Thursday, with the highest chances across the eastern Big Country. Highs on Thursday and Friday will be in the upper 80s to near 90. Slight chance PoPs will continue on Friday, mainly for our southeast counties.
