Valid 300100Z - 301200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF
THE NORTHEAST STATES...
...SUMMARY...
Scattered severe thunderstorms primarily capable of producing
damaging winds will continue across parts of the Northeast states
this evening.
...Northeastern States...
Weak mid-level height falls will spread across the northern Middle
Atlantic this evening ahead of the short-wave trough ejecting across
the Ohio Valley. A corridor of untapped instability currently
resides across the Middle Atlantic from VA into southeastern PA
where MLCAPE values range from 1500-2000 J/kg. Scattered convection
is approaching this reservoir of buoyancy and vertical shear remains
strong -- supportive of organized updrafts. 00z sounding from RNK
has sampled the convective generation zone well and this profile
supports maintaining SLGT Risk across this region until
thunderstorms spread toward the Atlantic Coast. For more information
on this scenario, reference MCD # 763.
Farther north across New England, organized convection is
progressing across northern NH into northwestern ME where a narrow
axis of instability remains. Locally damaging winds can be expected
for the next few hours with this activity.
