...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not forecast across the U.S. through tonight.

...Synopsis and Discussion...
An upper trough/low over the lower OH and TN Valleys late this
morning will pivot eastward over GA/the Carolinas into the western
Atlantic through tonight. Further deepening of a surface low over
the Gulf Stream east of the NC Outer Banks is forecast through the
period, but any associated thunderstorms are expected to remain
offshore. A separate upper trough with related cool mid-level
temperatures will approach the coastal Pacific Northwest late
tonight into early Sunday morning. However, NAM/RAP forecast
soundings suggest minimal MUCAPE will be detrimental to
lightning-producing convection.
