.KEY MESSAGES...
Updated at 935 AM CDT Sat Oct 24 2026

 -  Afternoon RH values will drop into the 25-35% range each of
    the next several afternoons, creating the need for extra
    caution regarding open outdoor flames.

.NEAR TERM...
(Tonight)
Issued at 230 PM CDT Sat Oct 24 2026

Under high pressure influence both at the surface and aloft, clear
skies have allowed temps to heat into the high 60s to low 70s. The
mild conditions will continue through the afternoon with RH
dropping into the mid 30 percent range during peak heating hours.

Clear and calm conditions will carry over into the overnight
periods presenting ample conditions for radiational cooling. Lows
will drop into the mid 40s, with urban areas staying a few degrees
warmer in the high 40s to low 50s. Despite calm winds, dew point
depressions do not appear to be low enough to support any fog
formation.

.SHORT TERM...
(Sunday through Monday night)
Issued at 935 AM CDT Sat Oct 24 2026

The highly amplified 5h ridge over the lower MO valleys through
the Sabine River valley will shift slowly east through Monday.
Shortwaves will dampen down the ridge across the MO into the OH
valley. Surface pressures will gradually lower across the
southeast U.S. as the high weakens and temperatures warm a few
degrees. A near persistence temperature forecast expects highs in
the lower to middle 70s with a ridge valley split maintaining with
the nocturnal inversion settling in each night. Lows should be in
the lower 40s valleys/upper 40s to lower 50s higher elevations.

.LONG TERM...
(Tuesday through Friday)
Issued at 1007 PM CDT Fri Oct 23 2026

The persistent ridge of high pressure across the region will
still be intact early in the week. By mid week a series of mid to
upper level disturbances move through the Northern Plains and
Midwest, disturbing the ridge. The ridge will flatten and weaken
Wednesday into Thursday, but seems to hold up enough to keep the
sfc low and associated cold front north of the region. This would
keep any rainfall chances out of the long term forecast. Will
continue with the dry forecast through the week with a bump in
cloud cover Tuesday night into Wednesday as a shortwave slides
through. Otherwise, look for high temps to remain in the 70s
through the week with the warmest days occurring on Thursday and
Friday in the upper 70s. Overnight lows will generally be in the
upper 40s with some locations reaching the lower 50s.

.AVIATION...
(00Z TAFS)
Issued at 645 PM CDT Sat Oct 24 2026

A boundary over NW GA is forecast by mesoscale models to push
west again tonight. This should bring drier air back into the
terminals overnight. Despite light or calm winds, this drier air
should keep fog from forming at the terminals. Winds will pick up
to around 5 knots from the east during the day on Sunday to
between 5 and 10 knots. VFR conditions are expected throughout the
TAF period.
