My winter forecast is going to BUST! I know I was calling for a big winter and pattern flip, but the recent guidance has changed with a polar vortex that is expected to deepen and remain stronger than average into mid Jan. The long range outlook for winter looks like shit right now, I hate to be an alarmist but I dont see how we are going to get North Atlantic blocking with a polar vortex this deep. Looking at the European guidance, the polar vortex isn’t consolidated over Eastern Canada, it’s over the North Pole. I’m very disappointed with the lack of North Atlantic blocking on the models, and honestly I’m really pissed off. I have been looking forward to a severe 2+ feet Boston blizzard this winter, I thought we would have 2 or 3 of em but now it’s looking like we won’t even get 1, last time my area had a severe 2 foot blizzard was March of 2018.

The polar domain should get a bit less hostile later in December, but any major disruption is well over a month away and perhaps closer to two+ months away.

We should do fine later this month,,,especially northern half of region.

If there is a "blizzard" type of event this year, best shot is early March....with perhaps a smaller secondary maxima of potential early Jan before warmer interlude again establishes.

Shared this several days ago on another forum: 

Saw something interesting. My #1 analog in my blend for DEC was 1984.

Here is Cansips DEC forecast on top with DEC 1984 underneath

MJO in DEC,  1984 was 3,4,5,6...blue line

Screenshot_20211202-005644_Chrome.thumb.jpg.c97a9eeb7782b0ea726bdfc6c8cb6950.jpg

 

Very similar to the MJO forecast for this DEC although we might get to phase 7 sooner.

Late DEC, 1984 had a SSW.  JAN MJO went into COD, then 7,8,1,2. JAN, 1985 - 500mb:

Certainly I'm not saying we have a replica of JAN, 1985 coming but I am wondering if a late DEC SSW prediction & colder JAN is a distinct possibility?? 

 

The progression of DEC is eerily similar. Here is DEC 15-20, 1984:

Here is 0z GEFS for DEC 18:

Screenshot_20211202-010901_Chrome.thumb.jpg.9b57ac5089bbb7a52992ebc9ca8d8222.jpg

 

The SSW in 1984 occurred on DEC 29.  Progression of strat from DEC 20 on is below:

Screenshot_20211202-011715_Chrome.thumb.jpg.a0932b2908ce817c30714a37acab8946.jpg

 

Graph is from this great paper on that particular SSW:

END OF POST

Now since that post CFS is predicting a SSW at the end of month & Simon Lee pointed out on twitter that the EPS is predicting a weakening of PV. just something watch right now.

Forecast was for 5-10" with lollis to 20"

Up to almost 8" on the day, 9" on the event, still pounding and radar looks like this #firehose

Just give us lurkers an endless sea of storms that are 7-10 days away, all of which fail to materialize, and we'll make it through this winter just fine.  Maybe throw in a few completely unrealistic clown maps for good measure.

You asked for it, you got it!

This is actually looking really bad. I should have just stuck to my guns the whole time. The pattern change is upon us now, and it only looks to be getting better in Jan. The polar vortex doesn’t need to be super weak, as long as it’s not consolidated over the North Pole we will be fine with the other factors in place as good as they are.

There is nothing wrong with adjusting a seasonal forecast as things play out. Far too many professional forecasters and amateur forecasters cling to their forecasts   for far too long.  Some seem to think that adjusting  a seasonal forecast makes them appear to be wrong.  And for some it is a blow to their ego. 

Nearly everything we do in life involves making adjustments at some point.

It depends why you are doing it......I like to see how accurate I am when I compose it in late October/ early November. While I will adjust ideas in subsequent blog posts, the original outlook gets graded as is from November.

At this point, I am going to need a big event or two to catch up prior to the January thaw, or else my seasonal snowfall totals will likely be too high.

Still very possible we catch up, but I am obviously frustrated at this point.

This is a fail, should have stuck to my guns.
