The severe weather threat for Severe Thunderstorm Watch 364
SUMMARY...Significant damaging wind threat emerging in western
DISCUSSION...Storms that had developed earlier across the Texas
Panhandle have grown upscale into a mesoscale convective system/bow
echo that is now entering the western tier of counties in Oklahoma.
This system has a history of producing significant damaging wind
gusts of 80+ mph. Forecast soundings support the maintenance in the
short-term, with steep low- and mid-level lapse rates, rich
boundary-layer moisture (70F surface dew point temperatures), ample
instability (4000+ J/kg MLCAPE), and a developing low-level jet.
Outflow along the leading edge of the system has thus far kept pace
with the convection, suggesting the threat for significant damaging
wind gusts will continue for the next couple of hours across
southwest Oklahoma and affect central Oklahoma by 04-05 UTC.
