Yeah that was kind of weak sauce. I think there needed to be more southern stream. But who knows. It just didn’t want to pop that low to another level like most other guidance.

Can’t believe it’s been 3 decades since that storm.

Yeah there are some similarities aloft. But Feb 2013 had a monster high to the north and this one doesn’t.

Also going to get a death band as the fronto prob goes nuts while it’s moving NNW

Lot of seaward members on EPS taking a wide turn. But they do start consolidating closer to the cape on the next couple frames.

Yes once you see those 925s collapse in the CCB, the profile gets easily cold enough for snow at least away from the water. I do think places in CT that are getting a lot of WCB precip prior to the CCB need to look at the soundings very carefully.

Not super similar but some of the variables are…Dec ‘92 had a strong ULL diving down through VA and this one comes in further north but due to the eastern southern stream low, we end up with an easterly flow for a time that is somewhat similar. Dec ‘92 had a potent high pressure up north too which while not very cold, it really increased the pressure gradient and helped cause the huge winds (90+ mph gusts on the exposed shore) Airmass was pretty marginal in Dec ‘92 as well

Tomorrow technically since we don’t turn clocks forward until 2am

Still ends up getting you eventually. Lol. But yeah, guidance has to figure this crap out with the phasing.

GFS has a stronger primary this run. IVT will be an issue this solution.

18z Icon still has a dual low with the western one going into ginxys hood. No good for most of SNE.

There’s a reason we call them clown maps. They are fun to look at but they aren’t reality. They can be ok in uniform storms with a cold thermal profile but otherwise you need to really look at soundings and midlevels.

10 to 1 is April 97 for ORH.

Upper cape and then drifts east

Reggie is annihilation over interior SNE.

And Tblizz whining his way to another 30 burger.

I did too…but nuances are gonna be a pain in the ass to deal with on this storm.

That wasn’t the NAM, it was an experimental run from Scooters basement that accidentally got uploaded onto ncep servers.

Seeing the ensemble clusters made me feel somewhat better. OP is def on the northwestern 10% of those members. I also like how the trend on the EPS was to rotate it back ESE a bit faster. They really aren’t gaining much latitude north of CHH now. Thats not only good for limiting some of the warming, but it keeps much if area under favorable midlevel dynamics longer.

At least the OP looks on the western envelope…it’s still a possibility but most of those lows are further east and south at their furthest point NW before rotating back east…I’m hoping that means the OP run will regress back toward that next cycle like we’ve often seen the past couple days whenever we get a westward OP run

Euro doesn’t really sway my thinking that much. The IVT tug is something to keep an eye on, but even those solutions are trying to reconsolidate to the east…my gut says that happens a bit faster given the explosive height falls. Hopefully we keep the southern stream robust enough that we don’t need to worry about lows over ORH anymore like we were seeing on some previous runs.

It’s a 10 to 1 map too. In reality that’s prob more like 10-15” for us.

Yeah we need a more wholesale shift east I think for inside of 128 to see mostly snow. They probably get in on some good heavy snow bands on these cape solutions but not before a lot of rain first.

This is what I was describing yesterday when I said most of us in SNE wanted to see a more dominant southern stream low…it shuts off the WAA going on further west from the northern stream IVT and then focuses all the baroclinicity further east and the low goes nuclear out near the BM up to the cape region instead of having Steve’s dog logs getting burnt by ozone.

Metro west between 128 and 495 is probably the toughest area to forecast. I’d feel pretty good outside of 495…I think precip will flip to snow relatively quickly there but inside of 495 to 128 is a tough call. I’m not totally buying the dual low idea…it’s prob going to be one or the other…and that makes it hard to forecast because if a low in Westerly RI becomes dominant, then that will cut down on accumulations quite a bit in metrowest (won’t really affect further NW as much)….but if we’re already overlaying a cold conveyor from the east by Pre-dawn Tuesday, then metrowest would easily get annihilated.
