.SHORT TERM...
(Tonight through Saturday night)
Issued at 1228 PM CDT Fri Jul 24 2026

Some lingering moisture from the already decayed Bertha may allow
for a few isolated showers to develop today mainly over the Coastal
Plains or I-35 corridor. However, given the isolated nature of any
activity rain chances remain below 15 percent. Otherwise, dry and
hot conditions are seen although highs should be roughly 5 degrees
below those realized yesterday. With elevated humidity this
afternoon, heat index values will still be up to 100-106 for a
majority of the area. Southeasterly wind will be breezy at times
through the evening, then lighter wind returns overnight. Lows dip
into the low to mid 70s across the area with some areas of low
clouds expected by tomorrow morning. Clouds scatter Saturday
afternoon with another seasonably hot day for late July. Highs will
be in the 90s with heat index values around 100-104 degrees.

.LONG TERM...
(Sunday through next Friday)
Issued at 1228 PM CDT Fri Jul 24 2026

Persistent mid-level ridging keeps the forecast hot and dry in the
long term period. In the lower levels, a light to moderate southerly
flow will continue aiding in a slight warm up towards the middle of
next week. We`ll mainly see high temperatures in the mid and upper
90s Sunday but as the week progresses except to see more widespread
highs from 100-102 degrees. Low temperatures each day will be in the
70s. With a drier airmass in place, mostly sunny skies will be the
norm.

late morning improvement to VFR will follow areawide.
