Valid 201200Z - 211200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe storms are not expected across the continental United States
Tuesday and Tuesday night.

...Discussion...
Broad cyclonic flow aloft will remain in place over the northern
half of the U.S. Tuesday.  Within the larger-scale flow, a
pronounced short-wave trough will move from the northern
Intermountain region eastward to the Upper Great Lakes.  Elsewhere,
a weak upper disturbance will linger over the Florida vicinity.

At the surface, a quasi-stationary baroclinic zone will remain
generally in place from the southern Plains to the Lower Great Lakes
region, though its position will oscillate some during the period as
the aforementioned upper short-wave trough advances.  

In the vicinity of this front, a zone of showers and a occasional,
embedded thunderstorms will persist through the period.  Otherwise,
showers and isolated thunderstorms are expected from Florida
northeastward to the eastern Carolinas.  However, the environment in
both of these convective regimes will remain largely insufficient to
support more vigorous convection.
