Issued at 1236 PM CDT Mon Jul 20 2026

.LONG TERM...
(Tuesday night through next Sunday)
Issued at 1236 PM CDT Mon Jul 20 2026

High pressure parks itself over the Southern Plains for the
remainder of the forecast period, keeping skies sunny and
temperatures hot. Afternoon highs in the low to mid-100s will be
common through the end of the work week, with overnight lows
struggling to drop below 80. In some spots, these overnight lows may
approach near-record warm values. Heat Advisories are likely to be
needed through the rest of the week. There is a low chance of
needing an Extreme Heat Warning on Wednesday, as increasing
moisture combined with the hottest forecasted temperatures of the
week have resulted in forecast heat index values climbing above
110. However, this is the first forecast cycle to show such high
and widespread heat index values, contributing to the lower
confidence. All the same, make sure to take the necessary steps
to keep you and your loved ones safe from heat- related illness
this week.

The developing Tropical Depression in the eastern Gulf could throw a
welcome wrench into this period of prolonged heat. Current guidance
has come into alignment that this disturbance will approach the
southern or southwestern Texas Coast in the Thursday - Saturday
timeframe, which would bring increased cloud cover and rain chances,
along with cooler temperatures. That said, uncertainty remains high
with the details of this system`s progression, especially the track.
It is these details that will determine who sees rain and cooler
temperatures, and who doesn`t. So stay tuned.
