Areas affected...parts of the Northeast and southern New England

Concerning...Heavy snow=20

Valid 082321Z - 090315Z

SUMMARY...Leading corridor of winter storm across the Northeast will
produce a heavy snow band before transitioning to sleet/freezing
rain from the southwest. Heavy snowfall rates of 1-2 inches per hour
are likely.

DISCUSSION...A fast-moving swath of winter mixed precip will spread
across the Northeast and southern New England states through the
rest of this evening. Strengthening low to mid-level ascent will
yield a band of heavy snow along the leading periphery of this
precip plume where the thermodynamic profile remains entirely below
freezing. The initial swath should emanate out of the north-central
PA/southwest NY vicinity, where heavy snow has been observed, and
should expand east-southeastward along the NY to PA/NJ border area
over the next few hours. A longer-lasting deformation zone within
the cold-conveyor region should develop east from the Lake Erie
vicinity and move across much of southern NY during the next several
hours. A highly consistent signal persists across daytime guidance
with snowfall rates of 1-2 in/hr. The southern portion of the heavy
snow swath to about the Upper DE and Lower Hudson Valleys should mix
with/transition to sleet/freezing rain later in the evening.
