.DISCUSSION...
A few isolated strong thunderstorms continue this morning across
portions of northeast Oklahoma. Storms are forming in a CAPE
environment around 2000 J/KG with 30-35 knots of 0-6 KM shear.
Highest instability axis is generally along and west of an Osage,
Tulsa, McAlester line. This will support at least a marginal
wind/hail threat for the next few hours as activity pushes
southward before weakening.

Northern portions of MCS currently pushing through southwest
Oklahoma could potentially develop MCV type feature, moving
southeast along/just south of the Red River. Additional
thunderstorm development will be possible by late morning or early
afternoon across southeast Oklahoma on northern periphery of
feature, coupled with surface heating and approaching frontal
boundary. A few of these storms could be marginally severe given
the unstable air-mass expected, however weak deep layer shear
will likely keep most of these storm below severe levels. PWATs
approaching 2.00 inches will support very heavy rainfall with any
storms that develop. Several CAMS solutions suggest at least a
localized flooding threat with the slow storm motions expected/
potential training.

Isolated thunderstorm development is still possible on Wednesday
across far northeast Oklahoma as weak upper wave approaches in
northwest flow aloft. Better storm chances should stay north
across southeast Kansas. Slight chance pops will persist for the
remainder of the work week. ECMWF a little more aggressive with
upper trough moving through the central Plains on Saturday,
developing swath of heavier QPF across the area. Given the drier
GFS solution and the lack of any significant frontal forcing,
will continue with low chance pops for now. Temperatures should
remain near normal through the extended periods and stayed
primarily with NBM guidance.
