...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe storms are not expected on Monday.

...Discussion...
Broad, cyclonic flow aloft is forecast to prevail across the entire
U.S. Monday, around the primary polar vortex forecast to remain in
place over central Canada.

At the surface, cold high pressure will reside over roughly the
northern half of the country.  Meanwhile, weak low-level warm
advection is expected to evolve over the south-central and
southeastern U.S., as a weak short-wave perturbation within the
cyclonic flow field aloft crosses the southern Plains and shifts
into the Southeast late.

In response to weak low-level warm advection, and associated
weakening/retreat of the remnant front over Florida, showers and a
few thunderstorms will persist across the Peninsula and adjacent
offshore waters through the day, spreading northward with time. 
Showers and a few/elevated thunderstorms may also develop overnight
over the central Gulf Coast vicinity, in response to the subtle
increase in QG forcing associated with the aforementioned upper
short-wave trough.  In all areas, severe storms are not expected.
