long way to go - trended towards EURO

The vast majority of the time our snowfall comes from less than ideal setups, where a lot has to go just right for an all snow event. 

That said there are some features working in our favor which have been largely lacking in the last 2 years:

1.) High pressure to our north (we always had a low in the Great lakes area last two years). Would want in slightly west of that depiction however that is a cool air source.

2.) A deepening predicesor storm which is providing SOME confluence, which of course can help limit the northern trends.

3.) A storm crashing into the west coast, which, if timed right, can kick our storm east BEFORE allowing it to gain to much latitude (i.e. keeping us on the NW side.

Not a perfect -EPO/PNA/-AO/-NAO setup, however one that gives us the best threat in a couple years. Great to be able to track something.

traced the storms back to the present/hour 0 and they are still quite far away at present. don't know enough to determine how this impacts prediction, but wanted to share anyways

When the systems hit the west coast, there will be better sampling. Wait and see for a couple of days.

It’s a threat in the board-saying again. But I’d rather be on the northern edge of the snow hoping for a north trend to get in the game vs right on the R/S line at this point. We’ve seen over and over what normally happens with these as get closer to game time. I’d say we need the 1/4 event to be stronger so it can form a 50/50 and block the 1/7 event from trying to cut or hug the coast. Any stronger storm without a block to force it south will try to cut north and pump the SE ridge ahead of it.

Sensitivity analyses will be fun to unpack once this event gets a bit closer. Trying to dissect an ensemble analysis at 180 hours lead time won't serve much purpose, however quickly glancing at it since its hard to resist, it does highlight the timing and strength of the jet stream phasing across Baja CA and NW Mexico as a key proponent to this materializing into anything good, in addition to any blocking potential across northern New England.

Every threat last year did the same thing. The cmc and gfs gave us about 10 feet of virtual snow

Huge differences over last year though. We do not have a monster RNA overpowering everything. We do not have a low pressure in the great lakes for every event like last year. Very different.

But once the models settle on a rainstorm they usually don't budge. Luckily we haven't gotten to that point yet aside from the euro

Right, if we have a strong storm coming up the coast and there’s a mechanism to provide cold air and overrunning like a big high, it’ll be a snowy outcome somewhere for sure. We just need something to force it on a more NE vs N track, or force it E before we start changing to rain.

Yup, our best potential in a while. I don't think it will be the last either.
