.SHORT TERM...
(Through Saturday)
Issued at 1125 PM CDT Fri Jul 24 2026

Weak mid level trough axis will slowly pass east through the
forecast area through Saturday morning and may support an isolated
shower or storm similar to ongoing radar trends. Coverage will
likely remain very low. Corridor of deep moisture has overspread
the forecast area per 00z regional soundings and 24 dewpoint
changes show a rise of 5 to 10 degrees for much of the local
region. Steadily rising mid level heights are expected though the
day Saturday as ridging expands eastward and temperatures will
respond accordingly. The combination of deep moisture and expected
warming yields dangerous heat conditions this afternoon across the
forecast area. Ongoing heat headlines reflect the latest forecast.
An isolated afternoon thunderstorm could develop within the
higher terrain of western AR on the periphery of the expanding
upper ridge, but again, any coverage will likely remain very low.

.LONG TERM...
(Saturday Night through Friday)
Issued at 1125 PM CDT Fri Jul 24 2026

Upper ridge expands further eastward Sunday through Tuesday and a
steady rise in daytime highs are expected. Dewpoint trends may be
slightly drier but confidence is low in exactly how much. Despite
the exact values, the overall pattern is supportive of continued
dangerous heat through early week and further heat headlines are
expected.

Potential for a weak frontal passage Monday night into Tuesday
with the upper ridge slightly weaker by mid to late week. The
stalled frontal zone on periphery of the upper ridge may allow an
increase in shower and storm chances and slightly cooler
temperatures. There does remain a notable spread in ensemble
guidance at this range so the magnitude and timing of any cool
down is uncertain.

.AVIATION...
(06Z TAFS)
Issued at 1239 AM CDT Sat Jul 25 2026

VFR conditions are likely through the forecast period for all
sites. Isolated showers remain possible through the overnight and
early morning hours, mainly across NW AR sites, though
probabilities were too low to include in TAFs at this time.
Otherwise, a mix of mid and high clouds are expected through the
forecast period with increasing south-southwest winds during the
afternoon hours.
