...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected today through tonight.
...OH Valley...
An upper trough is moving across the Great Lakes region today, with
a 100kt mid-level jet nosing into NY. The associated surface cold
front will sag southward into parts of WV/KY/TN this afternoon and
evening. Southwesterly low-level wind ahead of the front will
continue to slowly moisten the air mass, leading to a corridor of
marginal CAPE. This will lead of a line of showers and occasional
thunderstorms from central WV into west TN and eastern AR...mainly
after 00z. While an isolated strong wind gust cannot be ruled out,
the threat of severe storms appears low.
...CA...
A strong and progressive upper trough will move into central CA this
afternoon and evening, providing widespread lift and mid-level
moisture across that region. Most model solutions suggest a line of
low-topped showers and a few thunderstorms along the front as it
moves inland after 21z. Gusty winds will be possible with the line,
but organized severe weather is not anticipated.

...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
No severe thunderstorms are expected on Wednesday.
...Discussion...
An upper-level low will move from the eastern Pacific to the Great
Basin on Wednesday. As temperatures cool aloft, sufficient
instability will develop from central California to the Great Basin
with scattered thunderstorm activity likely. The weak instability
and shear will preclude any severe weather potential.
East of the Rockies, high pressure and cool/dry air will limit
overall thunderstorm potential.
