.
SATELLITE ANALYSIS AND TRENDS...BIG PICTURE ITEMS FROM GOES WATER
VAPOR LOOP WERE UPPER LEVEL CIRCULATION (BUT IT DID NOT LOOK CUT OFF
AS A CLOSED LOW) NEAR THE NE PA/NY STATE BORDER.   JUST AHEAD  WAS
SIGNIFICANT MID LEVEL SHORT WAVE TROUGH INTERIOR SE NY  TO WESTERN NJ
AND TAKING ON MORE OF A NEGATIVE TILT.  SATELLITE DERIVED UPPER LEVEL
MOISTURE DIVERGENCE MAX JUST SOUTH OF THE SE MA ISLAND BUT EXTENDING
INTO EASTERN NEW ENGLAND. JET WAS WELL EAST  IN FAR WESTERN ATLANTIC
AND EXTENDING BETWEEN NOVA SCOTIA AND MAINE-
SE NEW ENGLAND.    ON THE MOISTURE FRONT...DEEP LAYERED MOISTURE WELL
EAST...BUT LOW LEVEL WINDS TAKE THE MOIST CONVEYOR BELT BACK INTO EASTERN
NEW ENGLAND AND ALLOWING SOME SEEPAGE BACK AS FAR AS EASTERN LONG ISLAND
AND EAST CENTRAL NY AND WITH COLD AIR SEEPING IN FROM THE WEST HELPING
TO MIX AND CHANGE PRECIP TO SNOW ACROSS NEW ENGLAND PAST FEW HRS.
LATEST NESDIS SNOWFALL RATE PRODUCT THAT SENSE SNOW IN THE CLOUD
FROM MICROWAVE SENSORS ONBOARD POLAR ORBITING SATELLITES WAS AT 1506Z
AT:http://weather.msfc.nasa.gov/cgi-bin/sportPublishData.pl?dataset=snowfallrateconus&product=region_snowrate&stamp=20150328_1506&loc=btv#image
AND AT: 1412Z AT:
http://weather.msfc.nasa.gov/cgi-bin/sportPublishData.pl?dataset=snowfallrateconus&product=region_snowrate&stamp=20150328_1412&loc=btv#image
WAS SHOWING GENERAL MAX SNOWFALL RATES IN THE CLOUD TO BE ACROSS INTERIOR
NE/E MA...SE TO S CENTRAL NH AND N/NW RHODE ISLAND...PRETTY MUCH RIGHT
WHERE THE COLD AIR AND WESTERN PART OF THE TROWAL/MOISTURE ADVECTION WERE
INTERACTING WITH EACH OTHER AND AHEAD OF THE STRONG FORCING APPROACHING
THE AREA ALONG WITH WEAK DIFFLUENCE AND UPPER LEVEL DIVERGENCE.
NOT A FORCEFULL TROWAL BUT ENOUGH EAST TO NORTHEAST/NNE GRADIENT AND
WEAK MOISTURE ADVECTION TO HELP CONTINUE TO PRODUCE STEADY LIGHT TO
MODERATE/OCCLY HVY SNOW CENTERED NEAR HIGHER SPOTS OF INTERIOR SE/E
CENTRAL NEW ENGLAND FROM THE NW/N RI-NE CT AREA NORTH INTO MA AND S NH.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 1615-1915Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...STRONG SEP LIKE SOLAR RADIATION HELPING
OUT ON PAVED SURFACES...BUT NONE THE LESS...SNOWFALL WILL CONTINUE
IN BANDS WITH ENOUGH FORCING AND WEAK TROWAL CONVEYOR BELT MOISTURE
FOR MODERATE/ISOLATED HVY THIS PERIOD NE CT/N RI NORTH THRU INTERIOR
EASTERN MA INTO SOUTHERN NH.  TEMP CLOSE TO  FREEZING ALLOWS MOST SNOW
TO ACCUMULATE ON NON-PAVED AREAS.  NEGATIVE TILTED TROUGH SHOWS ONLY
SLOW EAST MOVEMENT...SO GENERALLY WHAT YOU ARE SEEING NOW IN THE WAY OF
SNOW WILL CONTINUE TO OCCUR INTO MID AFTERNOON.
