Valid 171200Z - 181200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Aside from parts of central California Thursday morning, the risk
for thunderstorms appears low across the remainder of the U.S.
Thursday through Thursday night.

...Synopsis and Discussion...
Weak instability may develop across parts of south FL Thursday ahead
of a southeastward-moving cold front, but the lack of large-scale
forcing aloft and only modest low-level convergence along the front
suggest that thunderstorm potential should remain low. Otherwise,
thunderstorms are not expected across a large majority of the CONUS
owing to generally dry and/or stable conditions. One exception may
be across parts of central CA Thursday morning, where cool mid-level
temperatures and ascent associated with a progressive shortwave
trough may support very weak instability and low thunderstorm
chances early in the period. Orographic lift along part of the
Sierras may also encourage isolated storms.
