...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorm potential appears low on Thursday.

...Discussion...

An upper trough will migrate across the Northeast on Thursday, while
a second upper trough digs southward across the northwestern U.S.
Stronger flow associated with these features will remain confined to
the northern Rockies vicinity and over New England. High pressure
will build over the Midwest and Mid-Atlantic region in the wake of a
prior cold frontal passage. A seasonally moist boundary layer will
be in place from the central/southern High Plains through the
southern/southeastern U.S. Pockets of stronger heating and modest
destabilization across the warm sector will support scattered
thunderstorm development. However, generally weak vertical shear
will limit organized severe potential, especially given a lack of
focus for severe storm development.

The exception may be with a strong storm or two across the
central/southern High Plains in a post-frontal upslope flow regime.
A stalled front will become diffuse across the area on Thursday, but
vertically veering wind profiles could result in some modestly
enhanced vertical shear. Some guidance shows early day convection
and cloud cover across this area, resulting in uncertainty in storm
coverage during the afternoon and evening. Furthermore, lapse rates
will remain modest and low-level flow will be weak, precluding
severe probabilities at this time.
