Areas affected...northwest into central OK

Concerning...Severe Thunderstorm Watch 372...

Valid 220434Z - 220630Z

The severe weather threat for Severe Thunderstorm Watch 372
continues.

SUMMARY...An intense bow echo and rear inflow jet will be capable of
80-100 mph gusts, potentially as far southeast as the OKC metro.

DISCUSSION...Radar mosaic shows a mature and intense bow echo and
associated rear inflow jet over northwest OK late this evening. The
airmass ahead of this is very unstable with 3000-4000 J/kg MLCAPE.=20
Ample mid to high-level northwesterly flow and a very moisture-rich
boundary layer will favor further intensification and maintenance of
this bow echo southeastward into central OK. Recent HRRR models
runs are congruent with this overall convective evolution. Peak
gusts of 80-100 mph are forecast with the bow echo. Mesovortices
within the line will also focus intense wind swaths and perhaps
yield a brief tornado or two.
