...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Organized severe thunderstorms are not forecast across the Lower 48
states on Tuesday.

...Synopsis...
A large-scale upper trough over the Interior West will feature
several embedded mid-level vorticity maxima with the most notable
disturbance evolving from the central plains to eastern IA.  A
surface cyclone will develop east-northeastward from northwestern KS
to near the IA/IL/WI border during the period.  The left exit region
of a strong southwest-northeast oriented upper jet will overspread
the Cornbelt and promote the development of scattered showers near
the surface low and eastward along a warm frontal zone.  Strong
low-level warm air advection and meager buoyancy may result in a few
thunderstorms, especially late in the day and perhaps into the
overnight.  Farther southwest in parts of AZ and NM, cold 500-mb
temperatures around -30 deg C may support charge separation with
isolated low-topped showers that develop over the plateau of
northern AZ and parts of northern NM during the afternoon.
