AREAS AFFECTED...CT...RI...MA...VT...NH AND ME

CONCERNING...HEAVY SNOW 

VALID 121016Z - 121515Z

SNOWFALL RATES ARE EXPECTED TO INCREASE ACROSS MUCH OF NEW ENGLAND
THROUGH 15Z. RATES LOCALLY FROM 1 TO 2 INCHES PER HOUR ARE LIKELY
INTO THE REMAINDER OF THE MORNING AND PART OF THE AFTERNOON.

THIS MORNING...WATER VAPOR IMAGERY SHOWS A VORT MAX OVER THE MID
ATLANTIC AREA LIFTING NEWD TOWARD SRN NEW ENGLAND. ASCENT DOWNSTREAM
FROM THIS FEATURE IS BEING MANIFESTED BY COOLING CLOUD TOPS
ACCOMPANYING AN AREA OF PRECIPITATION FROM SERN NY THROUGH
CONNECTICUT AND WRN MA. FRONTOGENETIC FORCING AND LIFT SHOULD
CONTINUE TO INCREASE THIS MORNING IN VICINITY OF A GENERALLY N-S
ORIENTED DEFORMATION AXIS FROM VT/NH SWD THROUGH MA AND CT AS THE
VORT MAX CONTINUES NEWD. SURFACE LOW WILL DEEPEN OFFSHORE AND SELY
LOW LEVEL JET WILL STRENGTHEN AS FORCING FOR ASCENT ACCOMPANYING THE
VORT MAX SHIFTS NEWD. THIS WILL RESULT IN AN INCREASE IN WARM
ADVECTION SNOWS...MAINLY ACROSS PARTS OF ME. SNOWFALL RATES MAY ALSO
BE CONVECTIVELY ENHANCED DUE TO PRESENCE OF STEEP MID LEVEL LAPSE
RATES.
