SATELLITE ANALYSIS AND TRENDS...VARIOUS FEATURES FROM EASTERN MAINE
TO EXT EASTERN LONG ISLAND AND SE NEW ENGLAND ALLOWING MODERATE TO
OCCLY HVY SNOW TO HANG ON.  BIG PICTURE FEATURES WAS WOUND UP LOW NOW
LIFTING NNE AND CENTERED NEAR 41.4N/68.2W AND AT LEAST FOR NOW LOOKS TO
BE HEADING TOWARD THE GULF OF MAINE.  MOISTURE PLUME WAS WELL EAST AND
SE AND EXTENDED FROM HISPANOLA TO 41N/53W BUT THEN ABRUPTLY TURNS NW AND
THEN WEST INTO S NOVA SCOTIA AND FURTHER WEST  INTO EASTERN AND CENTRAL
NEW ENGLAND FROM.   THE WESTERN PORTION OF THE PLUME ACTING MORE LIKE
A TROWAL OR TROUGH OF WARM AIR ALOFT THAT HAS BEEN TILTING MORE WSW TO
ENE AND FUNNELING VERY MOIST ADVECTED AIR INTO COLD SURFACE CONDITIONS
AT THE SURFACE OVER EASTERN INTO CENTRAL NEW ENGLAND FOR AN EXTRA BOOST
IN SNOW PRODUCTION.   NOW THE TRICK FOR MODERATE TO HVY SNOW IS THE SET
UP DEFORMATION BANDS FOR LIFT WITH ONE SHOWING UP OVER E CENTRAL INTO
INTERIOR NE MAINE IN WHICH NORTHERN EDGES WEAKEN OUT TO BE REPLACED BY
ANOTHER BAND TO THE SOUTH WITH EACH BAND BRINGING HIGHER SNOW RATES
FURTHER NORTH.   SAME DEAL GOING ON TO THE WEST AND SW OF HERE OVER
CENTRAL TO S CENTRAL MAINE BUT HERE AN ADDED FEATURE IS OFFSHORE TO THE
CENTRAL MAINE COAST A VIGOROUS SHORT WAVE THAT WILL BE GIVING ADDITIONAL
ENERGY (IN ADDITION TO DEFORMATION) FOR SNOW PRODUCTION IN THE NEXT FEW
HRS.   THEN THERE IS THE PIVOT AREAS  NEAR THE RI-MA-CT BORDERS...ALSO
NEAR THE MA-NH-ME BORDERS AND JUST OFFSHORE NH AND EASTERN MA COAST  FOR
LOCALLY MODERATE/OCCLY TO ISOLATED HVY SNOW RESULTING IN GENERAL SNOW
RATES TO 1" AND ISOLATED RATES OF 2-3 INCHES PER HR.

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 1945-2245Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...THREE MAIN AREAS OF CONCERN AS TROWAL CONTINUES
ACROSS NEW ENGLAND, SURFACE LOW CONTINUES TO LIFT NNE TOWARD THE GULF OF
MAINE AND PIVOT AREAS GRADUALLY SHIFT OR REDEVELOP EAST AND NE OVER THE
AREA OF EASTERN NEW ENGLAND FROM E MA/E CT/RI TO MAINE.   DEFORMATION CAN
BE CONSOLIDATING IN SW TO CENTRAL TO E CENTRAL MAINE AND PIVOT AREAS
CONSOLIDATING RI...E MA INTO SE/E NH FOR LOCALLY HVY SNOWS THOSE AREAS
THROUGH THE PERIOD.    STILL QUITE A BIT OF LUMPY CLOUDS ON VIS JUST
OFFSHORE E MA AND MAINE TO CONTINUE TO SUPPORT THIS LOCALLY HVY PRECIP
WORKING SLOWLY INLAND MAINE AND EASTERN MA WITH FRINGE AREAS OF WEST
TO THE EAST TIP OF LONG ISLAND...EASTERN CT, RI AND CENTRAL MA STILL
GETTING AT LEAST MODERATE SNOW WITH A SHARP CUTOFF FURTHER WEST .
