...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
No severe threat is expected across the continental U.S. this
evening and tonight.

...DISCUSSION...
Northwesterly flow is evident on water vapor imagery over much of
the central and southeastern U.S. At the surface, a large area of
high pressure is located from the Great Plains eastward into the
Appalachians. A moist airmass is in place from the Great Plains into
the Southeast. Isolated thunderstorms are ongoing across parts of
the Great Plains and southern Rockies. A few strong storms will be
possible this evening near an instability axis from west Texas into
central Oklahoma, but no appreciable severe threat is forecast.
Elsewhere across the continental U.S., no severe threat is expected
this evening and tonight.
