Major Nor'easter for New England

[ronjon]

From Portland NWS AFD:

SUNDAY NIGHT IS WHEN THINGS SHOULD BEGIN TO GET INTERESTING FOR US. MODELS ARE IN GOOD AGREEMENT WITH BOTH THE TIMING AND
INTENSITY OF THIS SYSTEM. THE EXACT TRACK IS STILL A BIT UNCERTAIN...AS ONE WOULD EXPECT 2 TO 3 DAYS OUT...BUT THE SYSTEM DEFINITELY LOOK LIKE AN ACCUMULATING SNOW EVENT FOR THE WHOLE REGION. AT 00Z MONDAY THE SURFACE LOW SHOULD BE LOCATED OVER LAKE HURON WITH AN OPEN WAVE AT 500MB JUST NORTH OF LAKE SUPERIOR. BY 12Z MONDAY THE SURFACE LOW BEGINS TO OCCLUDE...WITH A SECONDARY LOW FORMING NEAR LONG ISLAND. AT THE SAME TIME...THE 500MB WAVE CLOSES OFF OVER THE GREAT LAKES. AT THIS POINT THE SYSTEM SHOULD
REALLY START TO SLOW DOWN AND WRAP UP. TEMPERATURES LOOK COLD ENOUGH TO KEEP THIS AN ALL SNOW SYSTEM...EVEN ALONG THE COAST. AT
18Z MONDAY THE SECONDARY LOW WILL HAVE FULLY DEVELOPED NEAR CAPE COD...WITH THE 500MB LOW LOCATED JUST NORTH OF LAKE ONTARIO.
SYSTEM BECOMES VERTICALLY STACKED AT 00Z TUESDAY OVER THE GULF OF MAINE...MOVING NEAR NOVA SCOTIA BY 06Z TUESDAY AS SNOW BEGINS TO
END ACROSS MAINE AND NEW HAMPSHIRE. THIS LOOKS LIKE IT COULD BE A PROLONGED EVENT OVER THE COURSE OF 24 TO 36 HOURS. ALTHOUGH SNOW
ACCUMULATIONS ARE A BIT PREMATURE...I WOULD EXPECT TO SEE 6 TO 10 INCHES AT MOST LOCATIONS WITH LOCALLY HIGHER AMOUNTS. AGAIN...THE EXACT TRACK OF THE STORM WILL HAVE A MAJOR IMPACT ON AMOUNTS.
