.KEY MESSAGES...

   degrees off the Caprock over the next several days.

 - Low storm chances return each evening Wednesday through Friday.

.SHORT TERM...
(This evening through Wednesday)
Issued at 1255 PM CDT Tue Aug 18 2026

Hot and slightly breezy conditions will continue the rest of today.
The upper high will remain over the Four Corners with upper flow
staying out of the north. The Heat Advisory will remain in effect
through 8 PM this evening as many mesonets across the Rolling Plains
are already near advisory level. An upper shortwave trough will move
across the Rockies into the Central Plains late this evening through
the early morning hours and will push a cold front southward, but it
will unfortunately not make it into the FA. Instead, we will see
thicknesses increase by nearly 2 DM by Wednesday afternoon and
increase highs by a couple degrees over today and will likely result
in another Heat Advisory being issued for the Rolling Plains.

&&

.LONG TERM...
(Wednesday night through next Monday)
Issued at 1255 PM CDT Tue Aug 18 2026

More dryness and heat is in store through mid next week. The
upper high will remain over the Four Corners through late week
before slowly pushing southeastward. While monsoonal activity
continues over the Desert Southwest, convection will stay mostly
out of the FA given weak steering flow. A few isolated diurnal
storms will be possible mainly across the Texas Panhandle as a
weakness rotates around the upper high, but chances of any of
these storms moving into the FA are low. The upper high will move
over the FA by mid to late weekend and will further increase
temperatures with highs reaching 100 or higher area wide by
Sunday. Some relief may come mid to late next week as the upper
high shifts to our southwest and places the FA under northwesterly
upper flow.
