The SREFs at 21Z (if anyone uses them anymore) are quite a bit wetter than 15Z
-
Taken literally about 2.2 at LGA but the BL is marginal this is an event that you’d have to be in the perfect spot for accumulating snow. Monday will have a very small axis where the snow accumulates. Especially if if only ends up far enough NW for the immediate coast

Active mid December with multiple event potential
SnowGoose69 replied to Typhoon Tip's topic in New England
The ICON at 18Z moved NW. I still think this is coming west. Maybe not to the degree the Op Euro was though -
I have noticed the last 2-3 model cycles that no matter what model you use if it is more NW with wave one its been more classic for the coast and organized with wave 2. The weaker wave 1 runs have tended to be uglier with wave 2, more disjointed etc. There may be no correlation given the sample size is small but its been obvious mostly in the Euro which by far has been the most amped model for Monday.

I didnt see it yet but the EPS will be confusing if people don't break out the Monday event. I wouldn't look at total QPF or snow amounts for a period. You have to look at each storm individually or on the surface/H5 panels or you'll be seeing totals for both events if you do 5-7 day total QPF
-
The weak or "fake phase" with more of a self amplification has some similarities to 12/09 and 2/83. I mentioned earlier that it showed similarities to 12/19/09 2/4/95 and 2/13/14.
-
Its inside the Euro amped bias window now and its also not a very strong/"phased" system which the Op has tended to go too strong on recent years . Given the trends the last 5-6 winters with these sort of systems I think the Euro may be correct on this one being NW
-
If you look at Op runs of various models the last 2-3 cycles there is no question the ones which are NW Monday have better setups for the coast Wednesday
-
IMO a whiff is more likely than a cut. Forky and a few others feel otherwise however. I think even if it "cuts" the system will be somewhat of a shredded POS and any type of S/W or system slamming into that high, even if it tracks inland from the coast might produce significant from end snows
-
The ICON often times does well at day 3-5 and sucks inside of that range. Its really strange but it has sniffed out trends or storms before when other models did not seem them. It might just be confirmation bias but the MA forum has mentioned the same thing
-
I just think its more likely this thing goes out than cuts. Even if it did "cut" there would probably be some sort of big snows on the front end, even to the coast because it won't be an amped/phased type system if it trends more in that direction. Right now I feel Monday is way more likely to go NW than out and vice versa for Wednesday.
-
CMC also bumped pretty hard north Monday. GFS did not really budge outside of noise. As I said with Wednesday its truly a mix of a bunch of events. I see some 2/4/95, some 12/21/09 and also some 2/13/14 in it
-
It doesn't remind me of any one setup. Its sort of a hybrid of a SWFE/Miller B to an extent. There are some similarities to 2/4/95 but the air mass in place is way better. There was no strong high to the north in that event.
-
One thing is almost for certain. Don't expect the GFS to show squat with it til last minute. I am sort of shocked its as far NW as it is with the system at the moment. It'll also probably show it as an all rain event too if it does come far enough NW for precip here
-
The first wave will also impact the next storm. So we more or less have to see what Monday does first
-
We've seen many of those types of events in recent years and they tend to look rainy at day 3-4 but as you get closer in models usually grasp the cold air bleeding in. They always look scary when you're 45/35 6-12 hours out and everyone is screaming bust
-
Monday is too far out to iron out but if you were to take the 06Z Op Euro literally its probably an all snow event even at the coast.

The difference this year is the -NAO is actually real in that over the next week it will be in place. I wouldn't be so sure the forecast on the EPS at 10-15 days of the -NAO are going to be fantasy as they have been most of the last decade. -

the most shocking thing to me here was that Caribou never broke the record of 59F they set in February 1994 for the warmest meteorological winter day. I figured for sure that record had gotten broken in the last 25 years -
I would be wary still of the euro being overamped at this range as it seems to be consistently the last 5 years. It was insanely overamped with tomorrow's evolution of this very system over OK/TX 3 days ago and has since gone the other way.

I've noticed the GFS when we have favorable patterns in the East for cold has always had a serious bias to tend to want to pull the ridge back west and dump cold air masses into the west or Plains Day 8-9 and beyond. Its been showing that the last few days consistently and the EPS wants no part of it. -

The last 1-2 days the Op GFS has pretty consistently wanted to torch the east and have a SER. Very bizarre because most runs it’s ensembles have disagreed -

There is no cold air in place ahead of it and when the system turns up the coast down by Georgia there’s a low in Quebec, not a high. You wouldn’t get snow with that system unless it was vertically stacked as it passed northeast of the area. In that case there would be an area of snow behind it
