Maybe, the ridge out west is very shallow and not particularly tall and amplified...but the shortwave drops in fairly far west in ID/MT/WY that despite that it has the time to still sharpen...as usual without the -NAO and a stout west ridge there are small differences which will impact this
-
Its not especially common to have an inland running Miller B...we usually either straight up fail because it redevelops at too far north a latitude or goes OTS....there are a few instances of classic Miller Bs which went over top of us or just west but its not a very long list. They've tended to occur when the western ridge is on or off the W Coast vs over the Rockies. What MAY happen here is this simply does not become a true Miller B and the primary goes way into OH/PA..

january 3rd potential coastal grazer

Its 100% of the time overdone but I don't remember any cases of it showing something that big 12 hours out and the event being a total whiff. I'm sure it has occurred though -

Almost all of their big La Nina snow events occurred in fast flow patterns with no -NAO where a storm was not able to go NW -

Pre upgrade this would freak me out as the Euro was automatically 30-50 miles too far SE with everything, but last few months its been on the nose mostly. -

UKMET looks unchanged from 00z -

The GFS has probably never scored a win on a mainly/entirely southern stream based event. -

The FV3 has been wildly inconsistent for the last year when I have looked at it. I never know when to trust it...the SREF is ALWAYS overdone, however its usually not this deviated from the NAM at 24...its safe to say one will probably be wrong by a good margin -

The 12Z HRRR looks more or less like the 06Z Euro...for now I go nothing over C-1 for the NYC area but this is an uneasy 18 hours for sure because any nudge north and you've got several inches of snow -
You can see already thru 24 hours the NAM is coming NW but that is not saying much since it basically was nowhere near any other model so far
-
Since the recent upgrade its exhibited less of the overamped bias from 90-120 it had been having as well as the suppressed bias it was having inside 72 but the sample size is small
-
The GFS has been lousy recently. I would not put much into that solution and the EPS was not markedly NW of the Euro Op
-
I still cannot believe how out there the NAM is with this system down in the MA in 36 hours.
-
Yeah. I posted a few days back that many forecasters who did longer range stuff were excited in Sep/Oct 95 about the winter. One guy who used to do MA outlooks even as recently as a few years back predicted 50 inches for DC that winter which most would think was insane any year and he was correct.
-
In my lifetime 02-03 is closest...we moderated for a short time in mid December but I don't recall a massive thaw in Jan/Feb as we saw in 93-94 or 95-96
-
That happens on occasion in La Ninas due to progressiveness of the pattern. DCA/BWI in general do way worse than NYC in La Nina winters but they have had some decent snow events and they are almost always a product of either fast/progressive Pac flow or northern stream shunting
-
Yeah there was arguments 93-94/95-96 were both active partly due to the long duration El Nino of 90-93 beforehand...in essence 90-91/91-92/92-93 were all Ninos but then why did 94-95 suck so bad. Pinatubo possibly played some role in 92-93/93-94 and 95-96 also. Remember 92-93, much like 96-97 was not that much of a ratter once you got away from the immediate metro.
-
Obviously social media and the internet hardly were in large use then and winter forecasts were not a big thing. However, there were actually quite a few Mets who were forecasting a big winter that year in Sep/Oct. I do not recall the reasons why but there was alot of buzz going around that the NAO was going to largely be negative and we had a good chance for a huge winter. The active tropical season may have been partly why they were hyping it
-
13-14 was, 14-15 I think was a +PNA
-
Probably...in 09-10 we likely would have gone over 90 if even the 2/6 storm hits us and we had other close calls...10-11 also was on pace to maybe break the 95-96 record but the pattern just collapsed.
-
13-14 and 14-15 both produced an insanely high amount of snow despite bad AO/NAO indices.
-
Monday has some potential but usually in those events I prefer to see the high positioned over far SE Canada or sliding offshore vs being up in Ontario. With a shearing out wave like that you could count on more overrunning being generated in those situations.
