Areas affected...western Oklahoma
Concerning...Severe potential...Watch unlikely
Valid 112311Z - 120145Z
Probability of Watch Issuance...5 percent
SUMMARY...Isolated storms capable of hail and wind are possible
across western Oklahoma this evening, but a watch is unlikely.
DISCUSSION...Visible imagery shows a substantial CU field across
western OK where hot temperatures have removed CIN along the
dryline. Meanwhile, robust low-level moisture remains in place with
southeasterly surface winds. The result is very strong instability,
and a zone of uncapped air. Surface convergence near the dryline may
be sufficient for a few storms this evening, with weakly veering
winds with height supporting a south or southwestward motion. Hail
and locally damaging wind will be possible should storms initiate.
