Preliminary forecasts of total snowfall

Maps after the words of the NYC NWS office….

LIGHT SNOW WILL DEVELOP
TONIGHT [after midnight]…PRODUCING UP TO AN INCH OF SNOW FOR THE SOUTHERN HALF OF
THE CWA[forecast area of NYC area, southern CT and Long Island]
AND 1 TO 2 INCHES OF SNOW FOR THE INTERIOR BY THE FRIDAY
MORNING COMMUTE.

……..
ONCE THESE 2 SYSTEMS PHASE…RAPID CYCLOGENESIS WILL OCCUR
OVER THE OCEAN…RESULTING IN WIDESPREAD HEAVY SNOW AND
STRONG…GUSTY WINDS. BASED ON THE LATEST FORECAST…THE BEST
CHANCES FOR BLIZZARD CONDS WILL BE OVER EASTERN CT…SO HAVE
UPGRADED THE WINTER STORM WATCH TO A BLIZZARD WATCH FOR NEW
HAVEN…MIDDLESEX…AND NEW LONDON COUNTIES. FOR THE REST OF THE
CWA…WINTER STORM WATCHES REMAIN IN EFFECT…ALTHOUGH IT IS QUITE
POSSIBLE THAT BLIZZARD CONDS WOULD EXTEND INTO LONG ISLAND…AND
POSSIBLY AS FAR WEST AS NYC AND THE LOWER HUDSON VALLEY.

MODELS COMING INTO BETTER AGREEMENT IN TERMS OF THE TRACK OF THE
LOW. ……

THERE IS STILL UNCERTAINTY AS TO THE TRACK AND POSITION OF THE
LOW. FOR NOW…EXPECTING A SURGE OF WARMER AIR AHEAD OF THE LOW ON
FRIDAY THAT WOULD CHANGE INITIAL SNOWFALL TO RAIN…BUT IF THAT
WARMER AIR DOES NOT MAKE IT…THEN WIDESPREAD SNOW WOULD FALL
THROUGHOUT THE REGION…AND SNOWFALL TOTALS WOULD HAVE TO BE
INCREASED. BASED ON THE LATEST FORECAST…WILL CARRY 6-10 INCHES
OF SNOW FOR MUCH OF NYC/NORTHEAST NJ. THE LOWER HUDSON VALLEY AND
LONG ISLAND WILL HAVE SNOWFALL TOTALS RANGING FROM 8-12
INCHES…AND CT WOULD RECEIVE THE HIGHEST TOTALS…GENERALLY
RANGING FROM 18-24 INCHES OVER EASTERN ZONES. THERE WILL BE
LOCALLY LOWER AND HIGHER AMOUNTS. ONE OTHER NOTE OF CONCERN IS THE
POSSIBLE SURGE OF WARMER AIR ALOFT. IF THIS MAKES IT TO THE LOCAL
AREA…THAT COULD RESULT IN LESS SNOWFALL…BUT MORE IN THE WAY OF
SLEET AND FREEZING RAIN.

HIGH WINDS WILL ALSO BECOME A MAJOR THREAT FRIDAY NIGHT THROUGH
SAT MORNING…PARTICULARLY FROM THE NYC METRO EAST…CT AND LI.
