...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected in the continental United States on
Saturday or Saturday night.

...Discussion...
As an eastern U.S. upper trough gradually shifts northeastward
across New England and into eastern Canada and the Maritimes, a
lower-amplitude/more zonal flow field will prevail across the U.S.
in its wake.  In the West, a short-wave trough moving onshore early
in the period will cross the Pacific Northwest and Intermountain
West, emerging into the Plains late.  A weak surface low/cold front
accompanying the upper system will likewise cross the Western U.S.
and eventually move into the Plains.  However, a largely cool/stable
airmass will prevail across the country, precluding any appreciable
threat for thunderstorm activity with this system, or elsewhere
across the CONUS.
