.SHORT TERM...
(This afternoon through Monday)
Issued at 1159 AM CDT Sun Jul 13 2025

Weak SE flow will lead to modest Gulf moisture advection through
this evening, however forcing remains minimal and the latest more
reliable CAMs do not show any convective development at all across
the area. While a stray shower or thunderstorm cannot be completely
ruled out given the daytime instability, a generally pleasant
remainder of the day should be in order with partly sunny skies and
highs reaching the mid-to-upper 80s. Quiet conditions will persist
into the overnight hours, with lows falling into the 60s. Despite
the continued light winds, moisture parameters somewhat improve
Monday, with PWATS around 1.25-1.5" off the Caprock. Again, not much
will exist in the way of forcing, however as with today an isolated
storm cannot be completely ruled out during the afternoon/evening
hours and CAMs are slightly more optimistic. That said, PoPs have
been capped at 20% and in general we should see very similar
conditions as today.

.LONG TERM...
(Monday night through next Saturday)
Issued at 1159 AM CDT Sun Jul 13 2025

The subtropical upper high currently centered along the West Coast
of California and Baja is expected to build eastward through
Wednesday, but it remains relatively weak compared to other
summers.  Drier northeasterly flow aloft should keep rain chances
rather low Monday night through Wednesday and allow daytime highs to
warm back into the 90s.

By Wednesday evening the weakness in the upper ridge (trough)
located in central Texas today should get stretched out and allow
some of the associated moisture to be drawn back toward the
monsoonal moisture axis remaining in New Mexico to our west.  As a
result, NBM guidance bring back chances of late afternoon or
nighttime showers and thunderstorms to most of the forecast area,
Wednesday and Thursday.  Rain chances will range from 10 to 50
percent, highest in the Southwest Panhandle and lowest in the
Rolling Plains. Those rain chances may be over done, but we don`t
plan on changing significantly from the NBM guidance.  The remainder
of the forecast for Friday and Saturday remains dry with seasonably
warm temperatures.
