MD 0077 CONCERNING HEAVY SNOW FOR PARTS OF THE NORTHEAST AND SOUTHERN NEW ENGLAND

Mesoscale Discussion 0077
NWS Storm Prediction Center Norman OK
0521 PM CST Sat Feb 08 2025

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

Concerning...Heavy snow 

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.
