....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorms are not expected across the U.S. on Monday.

....Discussion...
Low-amplitude flow aloft is expected to prevail across the U.S.
Monday, with the zonal regime trending weakly toward a western
trough/central ridge/eastern trough configuration through the
period.

At the surface, a weak frontal wave along the slowly sagging
baroclinic zone should shift out of the Plains across the Midwest
through the day, and then across New England overnight.  In the wake
of this wave, the surface front will continue shifting
southeastward/southward across the central and eastern states.  By
late in the period, the front should stretch from coastal New
England southwestward to the Mid-Atlantic region, and then
west-southwestward across the Tennessee and Lower Mississippi
Valleys into Texas.

While very weak low-level theta-e advection is expected ahead of the
southward-moving front, moisture return should be quite insufficient
to support appreciable destabilization.  Meanwhile, with Arctic air
spreading southward behind the front, a thermodynamic environment
insufficient to support deep moist convection is forecast to persist
across the U.S. through the period.
