...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not forecast on Wednesday.

...Synopsis...
An elongated upper trough will exit the East Coast early in the day,
as another positive-tilt trough moves into the central CONUS. This
trough will extend roughly from the upper Great Lakes into the
southern Plains. Meanwhile, an upper ridge will exist along the West
Coast, with additional disturbances diving south into the northern
Rockies.

At the surface, a stable air mass in terms of convection will exist
due to high pressure. A weak surface low may form from the FL
Straits toward the Bahamas, avoiding the FL Peninsula where the air
mass will remain stable. As such, little to no lightning activity is
forecast across the USA on Wednesday due to the stable air mass over
land.
