Areas affected...Central and Northern Oklahoma into Southeast
Kansas.

Concerning...Severe potential...Watch possible 

Valid 302015Z - 302145Z

Probability of Watch Issuance...60 percent

SUMMARY...Severe storms in southwest Oklahoma are expected to
continue northeast through the afternoon with primarily a damaging
wind threat.

DISCUSSION...The cluster of storms in southwest Oklahoma has a
history of producing 60 to 70 mph winds so far along its path.
Considering the thermodynamic environment ahead of this cluster
(3500+ J/kg MLCAPE) this cluster will likely continue to grow
upscale as it moves northeast. While 0 to 6 shear is relatively weak
(25 knots on the 18Z LMN sounding), it has proven sufficient for
multicell organization of ongoing convection. Given the large
buoyancy, large hail will continue to be a threat, however, damaging
winds will be the primary threat from these storms.
