.SHORT TERM...
(Today and Tonight)
Issued at 1230 AM CDT Sun Sep 21 2025
Scattered storm activity north of I-40 this morning will gradually
wind down overnight as lingering instability is used up. The threat
of severe weather and flooding should also diminish over the next
few hours. Low temperatures will fall into the mid to upper 60s for
most areas.
During the day Sunday storms will develop by the late morning or
afternoon, moving from west to east. Storm activity will then
gradually becoming confined to southeast OK and northwest AR by the
evening as a shortwave trough moves overhead. Severe weather is not
expected Sunday, but an isolated marginally severe storm is
possible. High temperatures will be cooler than yesterday for most
areas, generally in the mid to upper 80s.

.LONG TERM...
(Monday through Saturday)
Issued at 1230 AM CDT Sun Sep 21 2025
CAM/ensemble guidance is in disarray for Monday with a general
signal for continued activity, but little agreement on the details.
Took a broad brush approach and kept most of the day with slight-
chance PoPs, with a late morning to afternoon maximum for northwest
AR. Confidence is very low in the specifics. A more potent shortwave
will approach late Monday into Tuesday. This shortwave will have
better mid to upper level flow and decent diffluence aloft. Low
level moisture will be plentiful with sufficient instability in
place. These factors will support the potential for a more robust
complex or two of storms to move through. These storms may be
capable of severe weather impacts, including large hail and damaging
winds, but confidence is low on specifics at this time. Another
potential concern will be flooding rains if training storms develop
along a stalled frontal boundary. We will monitor this potential in
the days ahead.
The main trough axis will move east by Wednesday, with storm
activity trending down into Thursday. Temperatures will cool during
this period, with highs falling into the upper 70s or low 80s for
many areas. Low temperatures will settle into the mid 50s to low
60s. Ensemble guidance also shows drier air moving in, with dew
points dropping. It will not necessarily feel like fall, but
conditions will be noticeably cooler than what we`ve seen recently.
Dry weather will then last through the end of the forecast period.

(06Z TAFS)
Issued at 1230 AM CDT Sun Sep 21 2025
A cluster of thunderstorms continues across NW AR currently with
storms winding down over NE OK from what was a busy night.
Thunder will still be possible over the next couple of hours with
some occasional MVFR or lower cigs and vsby with the heavier
storms in NW AR. A lull in activity is expected through the rest
of the morning hours before additional storm probabilities
increase again this afternoon across the region. If clouds clear
enough tonight, some patchy fog will also be possible, especially
across NW AR.
