.SHORT TERM... (This afternoon through Sunday) Issued at 1200 PM CDT Sat Sep 20 2025
West central Texas will remain under somewhat weak northwest flow tonight into Sunday. High resolution CAMs show scattered convection developing later today to our northwest across parts of the Texas panhandle southeast into northwest Texas. Some of these storms could eventually reach parts of our northern Big Country area north of I-20 later tonight, so have kept a 20% chance for showers and thunderstorms going in that area. In addition, a weak shortwave trough will move through the southern plains Sunday, bringing another chance for isolated to scattered showers and thunderstorms. While the best chances will be north of I-20, there is a low chance for some of these storms to reach as far south as the Concho Valley, so have added some 20% PoPs south of I-20 as well for Sunday afternoon. Otherwise, temperatures will continue to be warm, with lows tonight in the mid 60s to near 70, and highs on Sunday in the mid to upper 90s.

.LONG TERM... (Sunday night through next Saturday) Issued at 246 PM CDT Sat Sep 20 2025
Upper level high pressure over northern Mexico will expand northward into our area on Sunday and Monday. This will result in near record high temperatures, with highs rising into the upper 90s to near 102 degrees across portions of the Big Country and Concho Valley. By Tuesday and Wednesday, an upper level trough begins to dive down out of the northern Rockies and into the central Plains. This will push a cold front into west central Texas Tuesday evening into Wednesday morning. Temperatures on Tuesday ahead of the front will be hot, with highs in the mid to upper 90s. It should be noted, however, that the NAM is much faster with the progression of the front and would result in much cooler temperatures for Tuesday than what is currently reflected in the forecast. Regardless, highs will cool down into the 80s for Wednesday and Thursday. Rain chances (30-40%) are highest on Wednesday when scattered showers and thunderstorms are possible along the front. Models indicate upper level ridging building back into the region for Friday and Saturday.
