Pretty amazing agreement on all models that there will be a prolonged period of snow in the Northeast from Northern Mid Atlantic to New England.

GFS & Euro starts it Saturday evening ends it Tuesday morning.
Canadian has the storm develop south more on Tuesday so it would end Wednesday morning

I have the end date on the thread as the 11th in case the Canadian model is right and we go into Wednesday with snow continuing. Will have mods adjust accordingly as we get closer.

--------------------

Basically, it's all going to come down to where this Polar front stalls. North of it all snow. Under it mix stuff. South of it all rain. Will it be south of NJ? North of NYC?

Here's what the Euro says for Monday morning.. North of blue line is snow. Darker greens would be moderate snows.

Some discussion tid bits from around.. It's all going to be about the front and the storm. NWS Philly says near or south of them which means it will be south of NYC which means NYC north could be all snow.

SATURDAY NIGHT THROUGH MONDAY NIGHT...THE LATEST FORECAST GUIDANCE
CONTINUES TO SHOW AN ARCTIC FRONTAL BOUNDARY MOVING SOUTH OF THE
AREA PUSHED BY A BUILDING AREA OF HIGH PRESSURE MOVING EAST
SOUTHEAST ACROSS THE GREAT LAKES. OVER RUNNING PRECIPITATION IS
EXPECTED TO DEVELOP ALONG THIS FRONT SATURDAY NIGHT AND CONTINUE
THROUGH TUESDAY...WITH LOW PRESSURE PASSING SOUTH OF LONG ISLAND
MONDAY AND MONDAY NIGHT.

THE FORECAST LIQUID EQUIVALENT RANGES BETWEEN AN INCH AND AN INCH
AND A QUARTER...MAINLY IN THE FORM OF SNOW.

AGAIN THERE DO REMAIN A FEW UNCERTAINTIES IN THE FORECAST...

IF THE HIGH IS STRONGER THAN FORECAST...IT WILL PUSH THE ARCTIC
BOUNDARY TOO FAR SOUTH LEADING TO LESS OR NO SNOW.

IF THE HIGH IS WEAKER THAN FORECAST...THE LOW WILL TRACK FURTHER
NORTHER BRINGING WARMER ALOFT WITH A POSSIBLE CHANGE IN THE
PRECIPITATION TYPE FROM SNOW TO FREEZING RAIN / SLEET / OR JUST
PLAIN RAIN.

THE PRECIPITATION COMES TO AN END ON TUESDAY WITH DRIER WEATHER
MOVING INTO THE REGION FOR TUESDAY NIGHT AND WEDNESDAY.

TEMPERATURES WILL REMAIN AT OR BELOW NORMAL THROUGH THE LONG TERM
PERIOD.

.SYNOPSIS...
A FRONTAL BOUNDARY WILL MOVE ACROSS THE AREA SATURDAY NIGHT
AND STALL NEAR OR JUST SOUTH OF THE AREA SUNDAY INTO MONDAY. AN AREA
OF LOW PRESSURE IS EXPECTED TO DEVELOP ALONG THE BOUNDARY OVER THE
WEEKEND AND MOVE OFF THE MID ATLANTIC COAST AROUND MONDAY. THIS
LOW WILL TRACK TO OUR EAST THROUGH TUESDAY AS HIGH PRESSURE BUILDS
TO OUR WEST.

PTYPES ARE
STILL UNCERTAIN FOR A GOOD PORTION OF THE AREA, AS THE TRACK OF
THE LOW, AND HOW FAR SOUTH THE FRONT PUSHES, IF IT LIFTS NORTH AT
ALL, WILL ALL HELP DETERMINE WHERE ANY TRANSITION ZONE WILL
DEVELOP. IT STILL LOOKS LIKE THE NORTHERN THIRD OF THE AREA WILL
SEE ALL SNOW, WHILE FAR SOUTHERN AREAS MAY SEE ALL RAIN OR A
MAJORITY OF RAIN, WITH AREAS IN BETWEEN SOME SORT OF WINTRY MIX OF
SNOW, SLEET, RAIN, AND/OR POSSIBLE FREEZING RAIN. WE`VE INTRODUCED
SLEET INTO THE FORECAST, AND WILL SEE IN FUTURE FORECASTS IF
FREEZING RAIN BECOMES MORE OF A THREAT.

Also... Keep in mind.... 1 inch qpf over 3 days doesn't mean blizzard. It's spread out.

So it can snow for few hours then break, then snow again 6 hrs later then break again. Or be light snow for hours on end with heavy at times.

For instance....

Saturday 1"
Sunday: 3"
Monday: 6"
Tuesday: 3"

Doesn't seem that bad like that but in total it could be over 10" in some areas. Don't ask where or how much yet! Too early.

It's full here. I think we have an answer to "how much snow does it take to bring down the MBTA". Hopefully Philly gets it instead.

Had some melting today so not bad now although corners are hard to see with the piles. Another 1-2" tomorrow.

Here's my forecast.

Scary that all 3 main models are showing 10"+ next 10 days.

Bridgeports normal snow total for February is 8.1".
They have 10 inches already. LOL 20th snowiest February on record.

If another 12" falls this month it will be the 6th snowiest Feb on record

NErn/ Central mass has 36-40 inches of snow on the ground +20-25 inches I don't know how cities like Lowell/Leominster/Worcester can deal with a 60 inch snow pack
