1200 AM CDT Wed May 01 2019

Areas affected...Southwest/south-central OK

Concerning...Severe potential...Watch possible 

Valid 010500Z - 010700Z

Probability of Watch Issuance...40 percent

SUMMARY...At least a few severe thunderstorms capable of severe hail
may continue to develop east-northeastward across
southwest/south-central Oklahoma. While the overall risk may remain
somewhat marginal/isolated, will monitor for a possible Severe
Thunderstorm Watch.

DISCUSSION...Weak warm advection and isentropic ascent focused to
the north of a convectively reinforced boundary is supporting
isolated strong to locally severe thunderstorm development across
southwest OK early in the overnight. There are some indications that
additional storms could develop and otherwise spread
east-northeastward across the region overnight. Mid-level lapse
rates are very steep with adequate elevated buoyancy/shear through
the cloud-bearing layer for the strongest storms to produce isolated
severe hail. Convective trends will continue to be evaluated.
