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.
