..The best storm I recall happening thus far this season came from a system that was all but completely obliterated into a pancaked nothingness, that came whip-lashed back in like 18 hours.

 

Well there was that storm that dumped 1-3 feet of snow from DC to Bridgeport. But if you mean Ayer, MA then yes.

Euro ensemble mean is a nice track just inside the BM, but there must be solutions all over the map just based on mean QPF...it extends measurable back into E Ohio.

 

Though the good news is I don't see any west of that, so I'm guessing it doesn't support the Ukie's Cleveland track.

That's been the thing we've seen on all modeling..Just a massive areal coverage of precip. Not a tightly wound close to coast solution.

 

So Freak can probably pull the ski poles out of his abdomen

Sounds kind of close to the GEFS. Selfish question - but would a just inside BM track put western coastal CT into mix?

Looking at the individuals there is a ginormous amount of spread for mid week

S MENTIONED ABOVE HIGH AMPLITUDE MID LEVEL TROUGH WITH A

SUBTROPICAL CONNECTION TO IMPACT THE NORTHEAST NEXT WED/THU. IN
ADDITION 1035 MB ANTICYCLONE OVER THE MARITIMES TO NEWFOUNDLAND WILL
SUPPLY INITIAL SURGE OF COLD AIR ON THE FRONT END. STILL A LONG WAYS
OFF BUT A HIGH RISK FOR A HEAVY QPF EVENT GIVEN SUBTROPICAL
CONNECTION. HOWEVER LOW PROB ON THERMAL PROFILES GIVEN UNCERTAINTY
ON AMPLITUDE AND POSITION OF MEAN TROUGH AND DOWNSTREAM MEAN RIDGE.
A SLIGHT HEDGE TOWARD A SNOW TO RAIN EVENT FOR THE COAST AND SNOW TO
ICE INLAND FOR THE FOLLOWING REASONS:

1)AIRMASS ON THE FRONT END IS NOT ANOMALOUSLY COLD...THUS SOMEWHAT
EASIER TO ERODE COLD AIR ESPECIALLY ALOFT

2) GOOD MODEL AGREEMENT ON LARGE AMPLITUDE RIDGE OVER THE WESTERN
ATLC FAVORS A MORE WESTWARD SURFACE AND MID LEVEL TRACK /NOT OUT TO
SEA/ OVER OR NEAR SOUTHERN NEW ENGLAND. THIS WOULD SUPPORT MID LEVEL
WARM LAYER TRACKING FARTHER NORTH.

SO ONCE AGAIN A VERY PRELIMINARY FIRST CUT WOULD SUGGEST SNOW TO
RAIN ALONG THE COAST WITH SNOW TO ICE INLAND. COULD BE SIGNIFICANT
GIVEN POTENTIAL QPF WITH SUBTROPICAL CONNECTION.

Glad we don't live there

 

 

You don't live where it rains?

 

 

The irony is that Dan's region (up near Methuen?...unless he moved) has had a huge ice storm more recently than Kevin's area...Dec 2008 was a disaster up there around Essex county while it was mostly rain in Tolland.

The only thing that might be more worrisome for plain rain is that on today's 12z guidance, the Quebec/Nova Scotia high has become the main source...it isn't bridging up with the Canadian prairies high anymore...there's an extension of the PV that develops a low down into the lakes region around the same time we get our coastal....so this would increase the risk of rain closer to the coast. Obviously that might not hold...but that is an example of what I mentioned yesterday saying "the synoptics could change".

I saw the low in the GL and was like heck where did that Biatch come from. Once Monday passes we should have a clue
