....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorm potential appears minimal.

....Synopsis...
A progressive, somewhat high-amplitude wave train will characterize
the mid/upper-level pattern through the period.  A strong shortwave
trough -- initially over the inland Mid-Atlantic region -- will move
offshore around midday to early afternoon, developing a closed
500-mb cyclone well offshore thereafter.  Upstream, a trough was
apparent in moisture-channel imagery from the northern High Plains
across WY, UT, southern NV, and southern CA.  This feature will
split through the period, with the northern segment reaching the
Upper Great Lakes by 12Z tomorrow.  Meanwhile, the southern portion
will move slower and to the east-southeast, forming a closed cyclone
over parts of AZ and NM by 12Z.  Isolated, brief lightning cannot be
ruled out this afternoon over northern/eastern AZ to northwestern NM
in a zone of increasing large-scale ascent preceding the mid/upper
trough.  However, low/middle-level theta-e appears too weak to
support a general/10% thunderstorm area.  Lack of low-level
moisture, instability and/or lift will preclude thunderstorms
elsewhere in the CONUS.
