Areas affected...western Oklahoma into northwestern Texas

Concerning...Severe potential...Watch unlikely 

Valid 302024Z - 302300Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated to widely scattered thunderstorm development is
possible late this afternoon and evening.  While stronger cells may
pose a risk for severe hail, they may not be particularly
long-lived.  While the need for a severe weather watch is not
currently anticipated, trends will continue to be monitored.

DISCUSSION...Deepening convection, including at least attempts at
thunderstorm initiation, is underway near the dryline across western
Oklahoma into northwestern Texas.  However, mid/upper support for
thunderstorm development appears likely to remain weak to
negligible, while inhibition associated with warming elevated
mixed-layer air spreading east of the southern Rockies continues to
increase.  With the dryline also forecast to tend to slowly retreat
westward/northwestward into this evening, the potential for
sustained thunderstorm development appears generally low, but an
isolated storm or two could briefly develop and intensify.  In an
environment conditionally supportive of supercells, large hail
appears the primary potential severe hazard before the storms
dissipate.
