Talked to DTX's Bill Deedler, a great met/climate historian, today, and he thinks this winter is following his analogs/outlook VERY closely in the early stages. A cold and somewhat dry Dec is not uncommon. Hint, hint...a slow start in these very early stages of the seasons means nothing and his call for near to above normal snowfall is still on track :-)

While we have some snow showers expected off and on through the week, Im really starting to get interested in the clipper and lake snow for Thurs-Sat. 5-6 days out is a dangerous time to look for ANY specifics, but the fact that it is present and fairly consistent on ALL models, as well as a breaking down of the block, and that is all you can ask for at this point. Has certainly gotten my attention!

Yeah I'm interested in it too. Probably won't have as much moisture if it tracks that far north, but it looks like a fairly active storm period shapes up soon.

Wow, Josh looking at the models beyond D3? You can tell things are getting desperate here. :P

I'm sure I and a few others will pull those models out of our hats once better models find some way to screw with that clipper next week. Although, I've heard rumors that the JMA isn't as bad as it used to be. :arrowhead:

What only 2 fantasy storms per run instead of 3? :axe:

:lol: I always LOOK at the models all the way to day 16 in the snow season (rarely look at them outside snow season). I look out for trends, model consistencies. Like, when a model is consistent in keeping a storm, even though it will wildly vary in placement each run, I feel it is something to watch, versus times when they show a massive storm one run then nothing the next, its nothing to see here. For instance todays clipper has been in some form on the models for like 10 days. And I have been casually watching it. What I DONT do is live/die with each model run as so many on here do. Its not good for the heart lol. You also have to look at the big picture, the calendar, and climo. I will also point out, once again, that 3-4 days ago people who now have a nice snowcover acted as if there was absolutely no winter weather on the horizon thru mid-December. I sound like a broken record, but everyone needs to relax & ditch the short term memory. Its coming.

I dont know if this will ease your minds or not, but fwiw there is no snow on the ground in parts of the U.P., northern WI, and not to mention VT, NH, and ME.

:snowman:

Hmm...a little too much model consistency for my liking actually. Its quite scary. 12z models looking good for Fridays clipper, of the big 3, GEM and EURO show more qpf than GFS, but we all know how useful qpf is at 2+ days out. Now, all the models are beefing up qpf in eastern MI and OH on Monday with this lake effect or whatever. Will be interesting to see what happens. If we can eek out more than 0.1" every 10 hours as we saw on Dec 1/2.

The Day 8 storm is most likely real. All models have a wave during that time, and the -NAO block will be breaking down. A rapid rise from -NAO to +NAO is a very typical (and expected) time to get a storm. We won't know the real nature of it (super clipper, southern/mid stream wave) for a few days, but I do think the threat in that range is very real. Having the PV over or near the Hudson Bay is also a good thing.

I agree, it IMO is our first real chance of a storm with some southern moisture involved in it. Now the question is will the southern stream give some moisture... IMO I'm leaning towards yes,

I was looking at the NAO as well earlier and ever since I have started forecasting I can remember storms when we go from negative to positive. It will def be something to watch as we get into next.
