Lots of snow for me.

Snow Tuesday/early Wednesday, snow to ice to maybe rain Dec 26-27.

Can you tell us what it showed?

I don't understand why he feels as though the warm pool needs to shift to allow for +TNH??? We have had intervals of it in this regime previously both last year and in 2022 ...

A tradition like no other .

If you are basing analysis off of the weekly output, I get it...all I'm saying is they are probably right given the Pacific trough regime that has become established and a probable reflection event looming later in January. I like to use those as probabilistic tools, rather than deterministic.

I doubt sun angle will be an issue lol

Is this the earliest we cancelled winter?

You wait all year for winter, only for it to be seemingly over in time for Christmas. Just unreal.

We toss the GFS. It’s coming…

Lets sneak that down to Cape Ann

All three deterministic 12z runs bring the trough eastward w/ a mega strong -NAO in place. Larry Cosgrove mentioned that cold could be coming back east by the New Year, but also noted the forecast is incredible difficult during that time frame. We have seen this exemplified as models are swinging wildly from one solution to the other. He notes the NE would take the brunt of this. I do think we are seeing December 28-29th as a step off point towards another cold front of the seasonal variety. That could have a decent amount of amplification with it, so it will need to be watched. It is what happens immediately after that which I think will determine the first weeks of January. 12z has a good look. I think the NAO is making its presence felt on modeling now. I normally defer to ensembles, but maybe not this time. I think ensembles are way behind the curve on this pattern right now. It is unusual for that to happen, but it does occur w/ complex setups. The Euro control and its ensembles(for the Weeklies) were night and day yesterday. I think this is one of these patterns which would be easy to over analyze. For now, I just admire the wild solutions that are out there. Kind of fun! I personally think the end game of this is very cold air getting dumped into the Lower 48. The mechanism is in place to unload a majorly cold airmass southward. We may not have a long lead for when this occurs. Things to watch as we go forward....strength and duration of the NAO. It is the counterbalance to the Aleutian low.

Nice mammatus clouds right now

The march towards summer begins after today. Sun angle season before ya know it.

For what it’s worth, people also like to make predictions (in any arena) so that they can go back later to prove to others that they’re right now and were right then, and smarter than others. (See board, this) .

I happily accept the euro op for the next 6 days.

For up here, It looks like most of the snow fall is Christmas Eve morning.

But… was it measurable if it was a trace?

Reached 40 here at around 10am, currently 36 & sunny

A canonical la nina is a VERY roller coaster ride- more roller coaster than typical climo. So expect tons of model chaos the rest of the winter. Our region is definitely a better place to be than the east or especially south. But just be warned...there's likely plenty of excitement and disappointment ahead.

We take the euro-and OT the entire week.
