Areas affected...portions of western and central Oklahoma

Concerning...Severe Thunderstorm Watch 394...396...

Valid 082303Z - 090000Z

The severe weather threat for Severe Thunderstorm Watch 394, 396
continues.

SUMMARY...Severe wind and hail will become common with merging
multicells and supercells over the next few hours.

DISCUSSION...Several multicell clusters and transient supercells
have recently developed across western into central OK, with a
history of at least marginally severe hail. These storms are
increasing in coverage and intensity along a diffuse and broad
baroclinic boundary, along the northern extent of deeper/richer
moisture. MLCAPE ranges from 1500-5000 J/kg along the baroclinic
boundary, and the ongoing storms are expected to move or propagate
east-southeastward toward the OKC metro along this boundary over the
next hour or so. Gradual upscale growth into an MCS is likely over
the next 2-4 hours, where severe gusts will become the main threat.
In the meantime, severe hail is likely with the more intense,
semi-discrete storms.
