Areas affected...portions of western Oklahoma

Concerning...Severe potential...Watch likely=20

Valid 112251Z - 112345Z

Probability of Watch Issuance...95 percent

SUMMARY...High-based storms with potential for damaging wind gusts
will continue this evening. A new Severe Thunderstorm Watch will be
issued shortly.

DISCUSSION...As of 2245 UTC, regional radar and satellite analysis
showed scattered high-based storms erupting near a thermally induced
surface low across western OK. Extreme heat, with temperatures in
excess of 110 F is supporting very steep low and mid-level lapse
rates. As storms continue to develop and shift eastward within 30 kt
mid-level flow they will encounter higher PWATS and stronger
buoyancy. Damaging down burst winds are likely given the deep
inverted-v profiles and high DCAPE. A new severe thunderstorm watch
will be issued shortly.
