Areas affected...Eastern New York and portions of northeast
Pennsylvania and northern New Jersey

Concerning...Severe Thunderstorm Watch 233...

Valid 062157Z - 070000Z

The severe weather threat for Severe Thunderstorm Watch 233
continues.

SUMMARY...A band of thunderstorms beginning to move out of WW 233
has shown signs of weakening over the past hour. However, residual
buoyancy and strong shear downstream may maintain some severe risk
into parts of eastern New York. Downstream watch issuance is not
currently expected, but trends will be monitored.

DISCUSSION...Lightning counts have trended down within an arcing
band of storms moving out of northeast PA and into NY. Concurrently,
GOES IR imagery shows a slight warming trend in cloud-top
temperatures, also suggesting a gradual weakening trend. Currently,
the best convective environment resides across eastern portions of
WW 233 - specifically far eastern PA into northern NJ and southern
NY - where a few robust cells continue to show periodic
intensification. Although some buoyancy exists immediately
downstream of the convective band (around 250-500 J/kg MLCAPE), the
overall weakening trend is largely expected to continue as the onset
of the early evening transition within the next 1-2 hours begins to
limit surface-based buoyancy and increase inhibition. However,
robust ascent ahead of a mid-level shortwave/vorticity maximum and
45-50 knots of deep-layer shear sampled by regional VWPs may
continue to support storm maintenance and occasional intensification
of cells and/or segments within the line. Given the aforementioned
thermodynamic challenges, this is not anticipated to be a widespread
threat, but localized areas of damaging gusts appear possible
through 00 UTC.
