...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not forecast across the contiguous United States
through tonight.

Fast zonal flow is present today across the northern 2/3rds of the
CONUS, with dry and stable conditions precluding organized
thunderstorm activity throughout the period.

A warm and moist air mass across south FL, coupled with strong
daytime heating, will result in a few showers and perhaps a
lightning flash. Strong onshore flow and cold mid-level
temperatures could also result in a lightning flash along the coast
of WA/OR. In both places, very weak thermodynamic parameters
suggest the threat is below 10%.
