06z euro ramped back up. Gonna be interesting to nowcast this today.
-
That’s around an inch of QPF BOS on that GFS run and the midlevel look supported it that run. Pretty healthy and a little closer to some of those previous GFS runs on the midlevel look except displaced a bit further east. We’ll see if we can get a little last second trend stronger with that initial WCB.
-
If we can get the WCB more established between now and go-time, then we’d prob see QPF increase across the region. You want to be drawing in that extra moisture into the CCB over the top of that legit cold dome to the west and we can wring it out.
-
or what he said…similar thinking
-
You have a bit of elevation too, right? That will prob help you in the first hour or two. I’d prob peg ratios for like 13 to 1 there but it wouldn’t surprise me if you got into a weenie band and went close to 16 or 18 to 1.
-
I actually don’t hate where I am right now. Been rare to say that the last few years.
-
NAM looked actually somewhat healthy that run with the conveyors. Still not totally there like some of those zonked GFS runs but it’s much better.
-
They are in a great spot as the midlevels start closing off. CF will enhance a bit too but it’s mostly getting into that great zone just as the midlevels close off…can help intensify banding and perhaps prolong it an extra hour or two. That zone could still shift a bit though and we’ll just have to nowcast where any smaller meso bands might set up.
-
Don’t let Ekster see this.
-
A lot of areas out east will start a bit slow. Prob a few rain drops or white rain at the onset while initial banding is west and then I’d expect it to all of the sudden go nuts.
-
Not for near BOS and SE MA. Pretty nice look there.
-
Could be some good early banding out there before things congeal eastward.
-
I was only half-kidding when I said Scooter to Tblizz might jackpot this. There’s a period where that zone could absolutely rip for 3 hours or so. If they get into one of those bands that’s 2-3”/hr, all bets off. I think there’s going to be an initial weenie band west out toward our friends in W/C CT and then things are rapidly going to try and congeal to the east.
-
It’s gonna be funny watching the south shore to Tblizz jackpotting with 8-10” after all the hand wringing.
-
I don’t think Boston is going to lose that much QPF at the beginning. Maybe a little bit as they wait for the BL to cool…Xmas 2017 needed a deeper dynamic cooling from higher aloft before flipping to snow.
-
NAMs have def been consistently the lowest on QPF aside from the previous Euro runs…but 12z Euro left the NAMs as the lowest now. I’ll feel a bit better if they bump up at 00z.
-
The “meh” is because I think too many get addicted to the higher end outputs. When you mentally start expecting a major major snowstorm with over 1” of QPF and then reality smacks you back to half that, there’s an emotional letdown. But in an absolute sense, this is still a pretty solid event….and there’s still a chance for some banding surprises too.
-
It’s probably going to be a pretty solid event for most of SNE. Those shifts are just confirming what so many have already posted previously….those zonked 1”+ QPF runs were overdone. A solid 0.4-0.7 QPF with decent ratios is nothing to sneeze at though…especially given the last couple of winters.
-
It’s frequently a red flag when NAM is paltry because the bias of that model is to be zonked with huge QPF. We’d be tossing it if it showed a solution tracking over Scooter’s Fanny. I don’t think there’s a reason to be crazy down on this event, but I don’t want unrealistic expectations either….widespread big warning totals (say lots of double digit amounts mixed with with high single digits) might be a heavy lift.
-
Yeah but it’s def a bit of a red flag for the higher end amounts. We’ll see how 00z goes.
-
3km might be even more Meh. Those runs were basically keeping the WCB and CCB completely disjointed. The WCB just runs east with all that convection. Which could be real too.
-
Lower QPF. Steady stuff is like a 4 hour band of moderate snow.
-
1/24 is more likely than 1/22. I think 1/22 is pretty much gone though can’t rule out some weenie snow on the Cape. Had a fleeting chance still maybe 12h ago but models are pretty happy to punt it now. 1/24 has some work to do but there’s enough interest on ensemble guidance to keep following.
