.SHORT TERM...
(This evening through Monday night)
Issued at 113 PM CDT Sun Sep 28 2025
An upper level ridge extends from northern Mexico to the central
Plains this afternoon. Surface high pressure was centered over the
central Mississippi valley region, and winds across our CWA were
generally light. The airmass remains dry with dewpoints mostly in
the 50s. This is allowing for large diurnal temperature swings.
Lows this morning were in the 50s and 60s again. Temperatures this
afternoon are in the 80s and most of the area will have highs in
the lower 90s. An upper level trough will move into western TX
tonight into Monday and this will bring some mid to upper level
cloudiness over the Southern Edwards Plateau. These clouds will
keep high temperatures down a few degrees Monday, but otherwise
not much change is coming through the short term period.

.LONG TERM...
(Tuesday through Sunday)
Issued at 113 PM CDT Sun Sep 28 2025
The upper trough will move across TX Tuesday. But, the surface
high will keep drier air over our CWA, and dry weather will
continue. There will be some warming in the middle of the week.
Highs will reach the middle 90s across most of the area outside of
the Hill Country Wednesday and Thursday. Winds will shift to the
east Thursday bringing some cooler temperatures Friday through
Sunday. Still no rain through the long term.
