.SHORT TERM...
(Through tonight )
Issued at 1244 PM CDT Sun Apr 26 2026

A mid level trough gradually ejects from the Rockies today, while a
warm front lifts north and moisture advection continues at the
surface east of a dryline and sfc low in Western/Central OK. The
eastern end of the warm front will likely struggle with its
northward advance, and the front is expected to end up draped across
our area this afternoon and evening, oriented NW to SE. This
maintains widespread 60+ dewpoints, with pockets of 70+ possible
this evening, and results in an increasingly unstable airmass across
the warm sector. With steep lapse rates and increasing wind shear,
the environment will certainly be supportive of severe weather and
any storm that develops and takes advantage will likely become
severe. All severe hazards will be possible this afternoon into
tonight, including large to very large hail, damaging wind gusts,
and tornadoes (particularly if sfc-based storms are present in the
evening).

With that said, storm coverage remains uncertain, and overall storm
chances remain fairly low... only between 20 and 40 percent this
afternoon through tonight. Warm advection storms will be possible
north of the front with additional isolated storms possible across
the remainder of the area as inhibition decreases, with preference
along the dryline/triple point. The environment will continue to
support severe weather into the overnight period, however,
thunderstorm and severe chances should generally trend downward by
late overnight/early morning. Overall, it remains to be seen how
many storms will develop to take advantage of the environment today,
but it is a day to remain weather aware and appreciate the potential.

.LONG TERM...
(Monday through Sunday)
Issued at 1244 PM CDT Sun Apr 26 2026

Additional thunderstorm development will be possible along and ahead
of an advancing dryline/frontal boundary Monday afternoon/early
evening, some of which may be severe. Based on the latest timing
expectations, this places far E OK and NW AR in the greater risk for
severe weather. Large hail and damaging wind gusts are the primary
concerns Monday. The front is expected to stall in the vicinity of
western Arkansas and SE OK Monday night into Tuesday as another
shortwave moves across the region. This results in yet another day
of severe weather potential, particularly along and south of I-40 in
E OK and into W-Central and NW AR during the afternoon and evening.

The cold front will eventually move south of the local area Tuesday
night, with high pressure providing a break from the active weather
pattern on Wednesday. Precip chances increase late week as another
shortwave passes overhead and an upper low moves east out of the
Desert SW. Instability during this period continues to look fairly
weak, so thunder chances remain much lower through the end of the
week with no severe weather expected. Quiet weather is possible
Sunday with another period of high pressure.

.AVIATION...
(00Z TAFS)
Issued at 625 PM CDT Sun Apr 26 2026

VFR conditions will prevail into the evening. The main concern in
the near term will be scattered storm potential across NE OK over
the next several hours. Used PROB30s to cover potential. Another
round of storms is expected later tonight from the west, mainly
across NE OK. Storm chances greatest at KBVO, a bit lower at
KTUL/KRVS. Kept TEMPO mention at KBVO and PROB30 mentions at
KTUL/KRVS for the overnight storms. Storm chances/coverage too
uncertain to mention storms at the SE OK and NW AR TAF sites at
this time. MVFR cigs are expected to overspread the region from
the south late tonight and will persist into Monday morning. Skies
will clear from west to east with a front during the day. Storm
chances Monday afternoon should be east of the TAF sites.

...HIGHER END SEVERE POTENTIAL THIS AFTERNOON INTO THE OVERNIGHT...

This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.

DISCUSSION...

Thunderstorm coverage is expected to increase by late this
afternoon across northeast Oklahoma. Multiple rounds of storms
are expected across northeast Oklahoma from late this afternoon
into the overnight hours. Storm coverage is more uncertain across
northwest Arkansas and southeast Oklahoma. Any storms that develop
will have the potential to produce all severe hazards, including
very large hail, locally damaging wind and tornadoes. Storms
during the overnight hours, especially across northeast Oklahoma,
will have higher-end tornado potential. The storm threat should
come to an end by around 5 AM.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Activation of the Regional Spotter Network Likely.

.DAYS TWO THROUGH SEVEN...Monday through Saturday.
MONDAY...Thunderstorm Potential...High Wind Potential.
TUESDAY...Severe Thunderstorm Potential.
WEDNESDAY...No Hazards.
THURSDAY...Thunderstorm Potential.
FRIDAY...Thunderstorm Potential.
SATURDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...

Strong to severe storm potential will increase Monday afternoon
along and ahead of a cold front. This potential will be greatest
east of Interstate 49 in northwest Arkansas, with lower potential
across extreme southeast Oklahoma. Large hail and locally damaging
winds will be the main threats. Another round of storms and some
potential for severe weather Tuesday afternoon, south of the front
across southeast Oklahoma and western Arkansas.

A lull in storm chances is forecast Wednesday, however storm
chances increase again for the latter part of the week with the
approach of another storm system. At this time, the severe weather
potential is expected to be low.
