.SHORT TERM... (Today and tonight) Issued at 237 AM CDT Sat Sep 6 2025
Early this morning, a cold front was bisecting the forecast area and as of 2 AM was located just north of a San Angelo to Brownwood line. The front will drift south through the morning hours and is expected to be south of I-10 by mid to late morning. Remnant moisture from what was Tropical Storm Lorena will continue to advect eastward from northern Mexico. Abundant cloud cover will prevail today and with a cooler airmass behind the front, temperatures will be well below normal. Scattered showers and a few thunderstorms will persist today into tonight, with the highest rain chances (30 to 60%) from the Concho Valley and Heartland southward to the I-10 corridor. While the threat for flooding rains is low today, precipitable water values will range between 1.5 and 1.8 inches, which will contribute to some heavy downpours at times. Highs today will generally be in the mid and upper 70s, with lows tonight in the 60s.

.LONG TERM... (Sunday through Friday) Issued at 212 AM CDT Sat Sep 6 2025
Some of the moisture off of the eastern Pacific wave will continue drifting across the area on Sunday and Monday. This will interact with some weak disturbances aloft and provide a chance for continued rain showers and thunderstorms across the area. Ample moisture will allow for efficient rainfall production that could result in fairly high rainfall rates. The Weather Prediction Center has outlooked the I-10 corridor with a Marginal Risk (5-15% chance) of seeing excessive rainfall leading to flash flooding. This will be the primary concern for Sunday and Monday.
Otherwise, the GFS and ECMWF develop high pressure across the Plains by midweek, which will keep our area hotter and drier. Highs are likely to return to the middle 90s by midweek.

.AVIATION... (06Z TAFS) Issued at 1250 AM CDT Sat Sep 6 2025
Expect MVFR ceilings to develop across the terminals towards daybreak and persist through late morning and early afternoon. The exception will be KABI where a combination of MVFR/IFR ceilings will prevail overnight into the morning hours. Isolated to widely scattered showers will continue overnight into the morning hours. Cannot rule out a few thunderstorms, but will not include thunder at the TAF sites and will watch radar trends for possible amendments. Ceilings expected to rise to VFR by tomorrow afternoon. Winds will remain light the next 24 hours.
