...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe storms are not expected across the U.S. Tuesday.

...Synopsis...
Positively tilted troughing within the upper flow field across the
U.S. will gradually shift southeastward out of the Rockies and
across the Plains/Midwest.  Meanwhile, ridging is progged to expand
over the West in the wake of this trough, and ahead of a large upper
low moving south-southeast out of the Gulf of Alaska.  

At the surface, high pressure will prevail across a large/expanding
portion of the country in the wake of a surface cold front moving
slowly southeastward across Southeast/southern Plains.

Showers and scattered thunderstorms are expected in the vicinity of
the front during the period, and flow aloft would otherwise be
sufficient to support organized convection.  However, relatively
weak lapse rates and weak large-scale subsidence atop the warm
sector should hinder convective intensity -- and preclude
appreciable severe risk.
