DISCUSSION...

There is an enhanced risk of severe storms this afternoon across

risk is located across east-central into southeast Oklahoma into
west-central Arkansas near an advancing outflow boundary. Very
large hail to around 2 inches in diameter, damaging winds to
around 70 mph and a low tornado threat will accompany the storms.
The tornado threat will be higher with any storm that can hug the
boundary. The storms may eventually congeal into a cluster with a
damaging wind threat into southeast Oklahoma this evening.
Additional storms are also possible across northeast Oklahoma
behind the outflow boundary and will pose a large hail threat as
well. Locally heavy rainfall and a limited flash flood threat are
possible across east-central into southeast Oklahoma as well.

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

.DAYS TWO THROUGH SEVEN...Monday through Saturday.
MONDAY thru WEDNESDAY...Thunderstorm Potential.
THURSDAY...High Wind Potential.
FRIDAY and SATURDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...

Low thunderstorm chances will return late Monday night and Tuesday
morning as a warm front lifts north across the area. A cold front
will move into the area Friday, bringing another chance of
thunderstorms. Unsettled weather will continue into next weekend,
with storm chances continuing.
