Purely analyzing that cfs look, I actually like the Atlantic better than the pac. That’s a clear -NAO (east based though) with ridging over the top of the trough. The epo ridge is a west based epo. For the epo to really be ideal for snow we need it centered right along the coast and poking a ridge into northwest North America. That position without any Atlantic help would lead to a southeast ridge. You can see the se ridge trying but being muted by the NAO. That could set up an interesting battleground across our area. I’d take that look over a lot of the other options.

@showmethesnow @C.A.P.E. The look briefly looks promising around day 10. We get a dump of cold post day 10 from that very temporary -NAO -epo. There might be a very short window but att guidance says it’s pretty dry. But after that the look across guidance is honestly not that good for a significant snow. It’s hard to find any examples of a decent snowstorm with that h5 look. It’s not a shutout look...we can get some snow in most patterns except a big SE ridge in January. But we would be hoping for some kind of progressive wave. Anything amplified would cut. Sound familiar. Rather than try to work with that I’m just holding on to hope that it’s wrong after day 10. I don’t really want to spend prime climo stuck in a pattern where our best shot is to root for strung out waves. ETA: root for the GEPS.

For now I’m hanging my hat on the fact the Atlantic looks good through day 10. After that hopefully it’s wrong. But the issue is it slides the tpv east. That pushes the NAO ridge east. We really need that to either cross the pole or drop. But I’m going to be mildly annoyed if we waste the first extended NAO ridging for 2 weeks then just as the pac gets better the Atlantic goes to crap.

That’s a colder look... but not as snowy typically. I preferred the seasonal temps with ridging over the top look better.

One positive sign so far is that there wants to be some blocking up top. When the Atlantic was hostile the epo took over. Now that the tpv is on that side there is ridging on the Atlantic side. So far there have been enough mitigating factors to prevent snow here. But if we keep a somewhat favorable blocky high latitude profile through prime climo that is unlikely to continue.

Eps looks good day 10...and the trough lingers because of it day 11-15, but I don’t like the overall look day 15. It will be really hard to sustain any cold with that look up top. Luckily guidance has very low skill there past day 10 and all the guidance agrees on a pretty good look day 10. Just have to hope the Atlantic doesn’t completely break down like the euro indicates because nothing supports the pacific becoming favorable enough absent any Atlantic help. Doesn’t mean the pac stays hostile, just it looks ambiguous and not overly hostile or helpful in the long range which given the very conflicted tropical signals makes perfect sense.

Naw we get big snows from storms that start out 300 miles north of Toronto and dive due south all the time. All you can take from that range and that crazy nonsense is the gfs thinks the amplification and blocking of the pattern is likely to continue.

No one mentioned it, probably because its worthless...but the euro weeklies did have a nice NAO signature straight through the whole run. Pacific is mediocre at best the whole time though.

Looking at the individual members, there is agreement on a big cutter day 9-11 and then most of the members that cause the "trough" look in the east after that are just cold and dry with a big high parked over the east. There are some wet members...but they differ on things and take another cutter over after that. There really is no support among either camp for a frozen event despite the h5 look. Its split between cold/dry and warm/wet.

Ideally that is how it works...creating a feedback loop in our favor.

sooner or later the wave train of 50/50's has to pay off!!! We only need a couple good hits to make a winter here.

Run flee scurry

No I was in PA that year.

They aren’t perfect but guidance often shifts towards them when they disagree. In the case a compromise was best.

I’ve had storms where I got 10+ and DC ~2”. I can’t remember one where I got 10+ and as close as where got 10” today got that little. I’m sure he’s happened but not recently.

You got double me so...lol. It was a bad weekend. Fringed. Eagles tough loss. This was one of the worst gradients I can remember with 10” about 30 miles south of me and 2.5” here. Oh well. This will be one to just forget and move on to the epic pattern ahead. I feel happy for the DC area though. This should raise spirits in here at least. DC is one more decent storm away from beating climo now.

How did you do?

No the one on 30 north of Hampstead

This storm is trolling me. After the banding set up just south of me last night the latest band is like 2 miles south of me and stuck. It seems that’s the furthest north it can get. Just went down to Walmart 3 miles south and it’s puking snow. Just flurries at my house.

2.5”

Looks like round 2 wants to fringe me too. Guess the snow gods are making up for lost time. Guess I should have taken the fringe risk more seriously. Just assumed it would pull the last minute north bump to save me as usual.

Lol I’ll survive. Bring fringed here is rare because with upslope from the 1000 ft ridges we get higher ratios and usually a mini qpf max so even if I was “fringed” at the synoptic level at the meso level I can take what would have been .15 qpf and bump it to .25 with upslope then go 20-1 ratio and boom 5”. That’s what happens a lot. But that all falls apart if I don’t get into good enough lift to get the ball rolling. This time the fringe was real because the northern most band set up just to my south and I was stuck in the subsidence of that a lot. I think some places north of me did slightly better from the modest waa wave but I might have been hurt by the sinking around that band that dropped 4-5” just to my south.

5 or 6 from what I hear Wanna trade?

Don’t you have 5” otg?
