.KEY MESSAGES...

- Hot and dry weather will persist through the upcoming week

- The hottest temperatures are expected Tuesday through Thursday,
  where highs will be around 105 degrees across the Big Country

.SHORT TERM...
(Today and tonight)
Issued at 149 AM CDT Mon Aug 17 2026

Upper level high pressure will remain anchored over the region
today keeping hot and dry conditions in place. Forecast
highs in the Big Country are just shy of heat advisory criteria so
will hold off on an advisory for this forecast package. Expect
highs of 100 to 104 degrees across most of the area under mostly
sunny skies. Overnight lows will remain on the mild side in the
mid 70s. Elevated fire weather conditions will persist although
lighter winds will mitigate the overall fire weather threat today.

&&

.LONG TERM...
(Tuesday through Sunday)
Issued at 1241 AM CDT Mon Aug 17 2026

Not much change in the upcoming week as hot and dry conditions will
continue for the next several days.  This is due to a 596dam upper-
level ridge that will remain the dominant feature across the
southern US. This ridge will retrograde westward on Tuesday and
become centered over west Texas through Wednesday. The warmest days
look will be Tuesday through Thursday when 850mb temperatures will
increase to 25-27 deg C.  There is a medium to high (40-70%) chance
for high temperatures to exceed 105 degrees across the Big Country,
so heat advisories could be needed those days.  High temperatures
are expected to be 100-103 for areas further south.

By late Thursday, the ridge will shift further westward and become
centered over the Four Corners region.  Temperatures will be a few
degrees lower but this likely will not bring much overall relief
from the heat for most areas. A weak cold front will push southward
into north Texas late Friday into Saturday.  While earlier ensembles
and a few deterministic runs showed low (<20%) chances for rain with
this front, the consensus now shows next to nothing so PoPs have
been reduced accordingly.

through the TAF period.
