.SHORT TERM...
(Today through Friday night)
Issued at 1219 AM CDT Wed Sep 24 2025
Low pressure is moving across eastern OK and NW AR this morning with
a cold front stretched from the low into west TX. Aloft an upper
disturbance is moving out of the Rockies and into the central
Plains. Moisture is streaming north from the gulf into the MS Valley
ahead of this system.
Through today the upper disturbance will move east with the surface
heading east in tandem. The cold front will continue to move toward
the gulf coast. PWATs of 2 to 2.5" will remain in place across the
local area through Wednesday and into early Thursday ahead of the
front. Lift will gradually increase into the afternoon. With the
warm and moist airmass in place, convection is forecast to become
scattered to widespread during daytime heating, but there is a
chance a QLCS drops SE from the ongoing convection in NE TX, OK, and
AR. This would arrive this afternoon or early evening with strong
gusty winds being the main threat. The soupy airmass will allow for
high rain rates as well.
Convection will decrease Thursday as the drier airmass filters in
behind the departing cold front.
Dry and cooler conditions are expected Friday.

Issued at 638 AM CDT Wed Sep 24 2025
A period of messy weather consisting of several rounds of showers
and thunderstorms will unfold today into tonight as a cold front
moves towards and across the region. Now through late morning,
conditions should remain fairly quiet with mainly VFR CIGs/VIS
prevailing. By midday, things will likely be ramping up as storms
start to initialize ahead of the front. This initial round of
activity will be fairly scattered however, some stronger storms
are likely and periods of gusty winds, reduced VIS, and lower CIGs
will be possible. Later this afternoon into the overnight hours,
storms are expected to become concentrated along a line ahead of
the boundary. As this line moves across the terminals all the
previously mentioned hazards will again be possible. There will
likely be a brief lull between the first and second round of
convection.

Issued at 1219 AM CDT Wed Sep 24 2025
Widespread rain today will provide some needed relief across the
region, with widespread 1 to 3 inches of rainfall expected. After
the front moves through the region, dry air will filter south,
dropping our minimum RH values down to 40%. Behind the front,
winds will remain light with 20-foot winds staying below 10 mph.
