NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
Bands of moderate to heavy snow generated by strong mid level
fgen forcing extend from NYC up into NE NJ and Orange County.
Per earlier spotter reports these are capable of producing
between 1-2 inches per hour. Appears these bands will drift
slowly W in deep layer E flow to the N of the H7 low off the NJ
coast, then weaken this evening while additional bands redevelop
to the east this evening over CT and Long Island. Sfc obs and
radar 0.5 deg reflectivity/CC show rain/snow line just E of
Farmingdale/Huntington as colder air slowly filters eastward.
Per the above have issued a winter wx advy to cover all of
Nassau and Western Suffolk as colder air filters in and changes
precip there to snow this evening. Otherwise winter wx hazards
remain in place, with warnings farther inland and advys for NYC
metro and most of southern CT, with accums ranging from 4-6
inches in the metro area, as much as 6-10 inches north/west, and
mainly 2-4 inches from New Haven eastward. Outside chance that
as the sfc low S of Long Island redevelops farther E overnight
in response to additional QG forcing riding northward up the E
side of the upper low, redeveloping snow bands on the back
side of the low could also bring higher amts to the forks of
Long Island where 1-2 inches have been fcst.
