Scooter what are your specific thoughts for early and mid Dec for new eng? I know you are muting any extended warmth or torches. But you think normal or a bit BN?

Well I'm still thinking we could get

Into a milder period sometime in the first week. Models have gained traction on that idea. What I'm not sold on is the depth and longevity of it, especially around our area. The overall pattern does support the chance of milder wx. However, if they underestimate the higher heights north of AK, then we certainly will mute any milder weather. This whole thing seems to be driven by convection in the IO. That will shift east so I'm thinking after mid month is when we may see changes to more winter wx perhaps. So I guess my whole idea is maybe N to a little AN to start December. That idea hasn't really changed. I certainly don't have high confidence either. I'm well aware of busts on either side, but that's my guess.

I think Tuesday could really overperform in terms of warmth. 

 

It does appear that the cooler air arrives pretty slowly.  NW Mass and the NW corner of CT maybe on the cooler side, but I suspect the remainder of CT, particularly east of the river will be on the mild side.  Of course, at this time frame I think it's pretty 'shot in the dark' with respect to that level of detail.  My take nonetheless.

Agreed. I have 61 as my number for BDL, although we don't do exact #'s on the site so it goes in as upper 50s to lower 60s. All you need is for the front to get delayed a little bit, which most of them usually do, and you've got a shorts and sandals surprise ;)

I like HMs ideas, pattern is 3 weeks ahead of 03.

That would put the end of Dec 03 torch in Scooters time frame for AN, then hammer time, in time for Christmas

Well today's ensemble guidance has certainly milded up in the first week of December. I hope the 2003-04 evolution stops. That was a miserable winter for many of us. Ballz cold and bone dry.

03-04 was my #1 analog for this winter, so glad to hear that from HM. That reminds me, don't think I ever posted my winter forecast here, so : http://www.southernconnecticutweather.com/forecasters-discussion/the-2014-2015-southern-connecticut-weather-winter-forecast

The way I see it is this:  Nino Decembers are usually a wildcard, but cold/snow chances really start to increase going forward.  Therefore, anything we get between now and the end of December is a bonus.  If we happened to get an average or above average December in terms of SF, then I think we're off to the races and Ray's forecast could very well verify.

Before everyone gets all keyed up and high off a warm early Dec..just remember that Nov was supposed to torch, and all of T giving week was supposed to torch..So far those didn't materialize.As long as the cold is nearby in Canada and the Aleutian setup is the way it is..mild ups and torches will continue to either diminish or disappear entirely

It is an exaggeration to say that all of T-day week was supposed to torch and an even worse one to say all of November was. It did look like early November would be a torch for a time in late October. But it became apparent that would not materialize in the final few days of October. Secondly, the current 3 day warmup was actually modeled pretty well. There was some ambiguity on what might happen after Wednesday but it never looked like a straight torch all week..most runs have always had T-day itself as cold. For a time it looked like we may get a cutter on Black Friday but that only lasted a couple runs.

I'm not saying this to support the idea that December will torch early on, but no need for the hyperbole. It has been mentioned many times already how the recent 10-15 ensembles have been flip flopping quite a bit post T-day and now into early December.

It does seem as if the beginning of December is going to have a mild period with more of an Aleutian Ridge and the strengthening of the Pacific Jet. Almost looks like a Nina with -20C to -30C 850s covering Canada, but little of that cold air south of the border...the greatest anomalies look to be in the Southeast where 850s approach +10C on the LR GFS. 

 

That block north of AK is varying a lot on long range modeling though, and that might really be key here...we have to determine the strength of that feature and its exact placement as it seems like part of the Aleutian High tries to break off and give us some colder air.

Yep the Aleutian ridge extent northward is key. If it taps into remnant higher heights up N of AK and turns into a decent -EPO/-WPO block, then all bets are off...esp for the northern tier. But if the ridge stays a bit flatter then we could have a milder period that lasts a week to ten days. Impossible to really say at this point.

Thus far, the trend this season has been to have higher heights up there so that would make me cautious in calling for any sustained warmth (beyond a few days). We'll see how it goes as we get closer. All we can do.
