...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected across the continental U.S. on
Tuesday.

...Synopsis...
Shortwave trough currently moving through the central Appalachians
is forecast to continue progressing quickly northeastward, moving
off the Mid-Atlantic coast by early Tuesday morning. An attendant
surface low will take a similar path, before then deepening off the
northern Mid-Atlantic and Northeast coast during the day. A cold
front will extend southwestward from this low, with a small portion
of southern FL likely still ahead of this front at 12Z Tuesday.
However, this front should continue quickly southward/southeastward
clearing the south FL coast and FL Keys by 15Z. Warm temperatures
aloft should limit the thunderstorm potential across south FL and
the Keys ahead of this front. Dry and stable conditions are
anticipated east of the Rockies in the wake of this front.

Farther west, a low-amplitude shortwave is forecast to move across
the western CONUS on Tuesday, with another shortwave trough forecast
to approach the West Coast late Tuesday night/early Wednesday
morning. Even so, the lack of appreciable moisture should limit
buoyancy, with stable conditions anticipated across the western
CONUS throughout the period.
