.LONG TERM...
(Monday night through next Sunday)
Issued at 107 PM CDT Sun Aug 23 2026

The upper level ridge will shift slightly west on Tuesday, but still
remain centered across New Mexico. This will result in another very
hot day across the area, with highs in the upper 90s to near 108. A
heat Advisory will likely be needed for the Big Country and portions
of the Concho Valley and Heartland.

Wednesday and Thursday, the upper level ridge shifts a bit farther
west. This will result in "less hot" temperatures, but temperatures
will still remain well above seasonal normals. Highs on Wednesday
will be in the upper 90s to near 104, with highs on Thursday in the
mid 90s to near 102. West Central Texas will be on the eastern
periphery of the ridge and the ECMWF and GFS are both indicating at
least isolated to scattered afternoon showers and thunderstorms
developing Wednesday and Thursday. For now have kept low rain
chances (15-30%) in the forecast, but these may eventually need to
be increased some. Drier weather should return Friday int Saturday.
Highs will continue to be above normal, in the upper 90s to near
104. Overnight lows will mainly be in the 70s.
