...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Organized severe thunderstorms are not expected through tonight.

...Synopsis...
Early evening water-vapor imagery shows a couple of mid-level
disturbances embedded within strong flow over the northern tier of
states.  The most notable mid-level shortwave trough is located over
the western Great Lakes, and this feature will move east to the
lower Great Lakes by early Tuesday morning.  An upstream impulse
over northeast MT this evening will move east-southeastward into the
Upper Midwest by late tonight.  Scattered thunderstorms have
developed along a cold front from southeast Lower MI southward into
the OH Valley.  The 8pm EDT observed soundings from Detroit and
Wilmington, OH both exhibited weak buoyancy (at or below 250 J/kg
MUCAPE).  Despite the strongly forced convective line, the cooling
of the boundary layer will limit the potential for stronger gusts
with time, and lessening storm coverage is expected by later this
evening as this activity moves to the central Appalachians and lower
Great Lakes.
