.SHORT TERM...
(Through tonight )
Issued at 1230 PM CDT Tue Sep 23 2025

Severe weather and flooding threats through early Wednesday
morning dominate the weather concerns for this forecast. Showers
and thunderstorms persist across northeast Oklahoma and far
northwest Arkansas at midday, with the heavy rainfall so far
having focused in this same area. Radar estimates a solid area of
1 to 2 inch amounts with highly localized totals around 3 inches
in Benton and Carroll counties. Cloud tops have begun to cool once
again with the ongoing activity near the Kansas and Missouri
border that has been moving to the south and east on the nose of
the low level jet and will largely pose a continued heavy rain
threat before moving out within the next couple of hours.

Development is ongoing in the vicinity of the cold front, as far
southwest as the OKC metro, with this boundary increasingly
becoming the focus for thunderstorms during the remainder of the
afternoon and evening. CAMs continue to perform reasonably well
with timing and evolution with what has occurred in the past 12
hours or so, including the aforementioned rejuvenation ongoing in
northwest Arkansas. While the threat will begin in northeast
Oklahoma and parts of northwest Arkansas, it will shift
southeastward with time into the late evening hours before
diminishing after midnight.

Very high instability is already present across most of the area
roughly along and to the south of Highway 412 with lower values to
the north due to the ongoing and persistent cloud cover and
showers/storms to the north of a quasi-stationary boundary. Low
level shear parameters continue to focus across parts of far
northeast and east central Oklahoma and into western Arkansas,
with the northern edge of the main resulting tornado threat marked
by the aforementioned boundary. With time, there should be an
evolution toward a more linear mode, especially into the evening
hours.

Toward midnight and into early Wednesday morning, more elevated
storm development may occur, featuring a low but nonzero severe
weather potential.

The Flood Watch has been trimmed across northeast Oklahoma, with
the bulk of the remaining heavy rain focused across far eastern
Oklahoma and western Arkansas. Precipitable water values around 2
inches are centered in northeast Oklahoma and into northwest
Arkansas, which is approaching the seasonal maximum.

.LONG TERM...
(Tomorrow through Tuesday)
Issued at 1242 PM CDT Tue Sep 23 2025

The front should have cleared the area by daybreak Wednesday,
although additional showers and thunderstorms are expected until
the main trough axis pushes through the region. Noticeably cooler
temperatures will be on deck for Wednesday and Thursday in the
wake of the front. The eastern edge of the upper level ridge will
expand northeastward into area to close out the work week and open
the upcoming weekend, leading to dry weather and a gradual
increase in temperatures, especially during the daytime. Into next
week, the area will largely remain between weather systems,
increasing the likelihood of a fairly prolonged period of less
active weather than we are currently experiencing.

.AVIATION...
(00Z TAFS)
Issued at 639 PM CDT Tue Sep 23 2025

Showers and thunderstorms will be coming to an end later this
evening, with ceilings lowering to IFR in most places overnight.
Conditions will be slow to improve during the day Wednesday, with
ceilings likely raising to MVFR by afternoon.

DISCUSSION...
A line of strong to severe thunderstorms is ongoing from west

Damaging winds, large hail, and isolated tornadoes remain possible
as this line of storms shifts southeast early this evening, with
the greatest tornado threat across far eastern Oklahoma into west
central Arkansas.

A few storms have also developed near a surface low and cold front
near the Interstate 44 corridor in northeast Oklahoma. Isolated
severe weather will be possible with these storms into the evening
hours, with damaging winds, large hail, and perhaps a brief
tornado possible.

Heavy rainfall will also occur with the storms, with a flash flood
threat continuing this evening into the overnight hours, mainly
near and east of Highway 75.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...

.DAYS TWO THROUGH SEVEN...Wednesday through Monday.

EXTENDED DISCUSSION...
Scattered thunderstorms will again be possible during the day
Wednesday as an upper level low moves overhead. Severe weather
chances will be low with this activity, but some hail and gusty
winds may accompany some of the strongest storms Wednesday
afternoon across northeast Oklahoma into northwest Arkansas.

After Wednesday, the pattern will be quiet with temperatures
around the seasonal normals and drier weather expected through
the rest of the week.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
Emergency managers and area first responders should monitor the
latest information this evening. Given recent rains in some
areas, and the potential for excessive rains through tonight,
preparations for more widespread flooding issues may need to
happen.
