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 -
The 80s/90s stretch I buy somewhat into the transitional AMO theory. There was evidence that back in the last period when AMO was beginning the flip from cold to warm there were many positive AO/NAO winters as well though we don't have the stats back in that 1920-1935 period.
-
I think it definitely has something to do with the overall crap pattern the last few years and no -AO/NAO since 2011 though.

The GFS pattern really looks 1980s like with the cold shots that keep ejecting south out of eastern Canada -

We are pretty much due for a winter where everyone forecasts wall to wall torch and it ends up like 93-94. I don’t see much reason to assume that happens this year but it’s going to be hard to duplicate last winter. This is sort of the opposite of going cold and snowy in 94-95 or 01-02 after the preceding winters sort of had a ton of things break in a favorable way. It’ll be hard to get the ratter this winter we had last year again -

If I remember right in December 88 the positive NAO killed us. There was probably 3-4 decent storms that came out of the Gulf but weren’t able to make the turn up the coast -
Has anyone looked at 85-86 as a possible analog? The La Niña was much weaker but the QBO looks similar, November was very mild and there was an active Atlantic tropical period that month as well like this year
-
It was a semi neutral after a La Niña though. Historically those have been terrible and we had a couple of more after that too including 11-12
-
And NYC will probably get more snow than they got last winter anyway. It’s almost impossible to get that little snow again. By accident we will probably find a 6 inch event somewhere
-
February 89 and December 89 both exhibited a bit of what we saw in 17-18. Sometimes you get a decent pattern with cold air during La Ninas but they are too progressive so you end up with MA and SE snowstorms but the Northeast misses out. Most always assume La Ninas are bad for places like DC/RDU/CLT but reality is if you get the right pattern for a few weeks those areas can cash in well whereas a similar setup in a neutral or ENSO might have sent the impacting system to their north.
-
The 20Z HRRR got that 02-03Z MOB forecast very close. Had 90kts at 925mb with 76kts mixing to the surface
-
There has definitely been several cases where its been present late November into December and flipped. 1993 was one I know of. I think it was there more or less all of November into mid December.
-
Has there ever been a case of identical US landfall spots occurring with 2 storms in the same year?
-
The EPS might be wrong on the MJO but believe me it isn’t THAT wrong!!! I could see us going longer in 7 and maybe edging into 8 before going nil and re-emerging to 6 but that CFS forecast isn’t going to verify
-
I’m beginning to wonder if we need a major La Niña or El Niño event to shuffle the pacific SSTS so that we don’t have this same issue with the MJO winter after winter for the foreseeable future
-
Oh yes that I knew. The one you mentioned though from 91-92 is the one I can’t recall the day but distinctly remember it busting.
