Areas affected...Central PA into parts of the Mid Atlantic

Concerning...Severe potential...Watch unlikely=20

Valid 192359Z - 200230Z

Probability of Watch Issuance...5 percent

SUMMARY...Isolated strong/damaging gusts are possible this evening.

DISCUSSION...Multiple low-topped rain bands are ongoing this evening
from central PA into parts of the Mid Atlantic, along and just ahead
of an eastward-moving cold front. Buoyancy is very weak to
negligible (with SBCAPE of around 100-200 J/kg or less) and no
lightning is being produced with these bands, but strong ascent
related to a vigorous mid/upper-level trough approaching the region
will sustain this activity through the evening, with some
consolidation possible along the cold front. Peak wind gusts have
generally been in the 40-50 mph range, but with flow increasing into
the 35-50 kt range within the 1-3 km AGL layer (as sampled by
regional VWPs), isolated damaging gusts will be possible within the
weakly convective rain bands as they approach the Mid Atlantic
region.
