Cumulus Clouds Increasing in Dryline Vicinity

A band of cumulus clouds is increasing in west Oklahoma and north central Texas as a dryline begins to move east and provoke thunderstorms in the region.
As the dry air begins to move eastward, we can expect these updrafts to become more intense as soundings have indicated about 2800 j/kg of CAPE (instability) is available for these storms. A few sounding analogues provided by the Storm Prediction Center indicate that there is roughly a 20% historical chance of a tornado, with nearly a 50% chance of significant hail based on historical events similar to this one.
