...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected today or tonight.

...Discussion...
A prominent upper trough will continue to spread southeastward from
the Midwest/Great Lakes toward the Mid-Atlantic/Northeast coast by
tonight. Surface high pressure and related cold/dry continental
trajectories will be increasingly prevalent east of the Rockies.
Near a south/southeastward-advancing cold front, isolated
thunderstorms will remain possible early today over the northwest
Gulf, while a few flashes of lighting are also possible with weak
convection across the southern Florida Peninsula, before flow veers
and stronger convergence shifts offshore. Lastly, a few lightning
flashes could also occur late tonight near coastal Washington within
the warm/moist conveyor preceding an approaching shortwave trough
and cold front.
