....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms will not occur through tonight across the
contiguous United States.

....Synopsis...
Water-vapor imagery early this evening shows a mid-level shortwave
trough moving east across southern ID/northern UT and downstream of
a larger trough over the eastern Pacific.  A few thunderstorms have
been observed this evening in association with weak
buoyancy/appreciable ascent with the ID/UT disturbance.  This
activity may linger for a couple of more hours before the zone of
stronger ascent moves east into a more dry environment farther east
in WY.  Elsewhere, tranquil conditions reside over much of the Lower
48 states owing to building surface high pressure over the
north-central U.S. and a departing mid-level shortwave trough over
New England.
