BOX on board...

  • uesday Night

    A chance of snow after 4am. Partly cloudy, with a low around 27. Chance of precipitation is 30%.

  • Wednesday

    Rain and snow. High near 42. Breezy. Chance of precipitation is 80%.

Think colder scenarios with this folks..With the weakening block it's going to track farther east and phase later..Always happens when we are in a phase change

The Euro is weird ... It has what you would think is an optimum track for us ...Off NJ to ACK... But it takes the main band of snow and shifts it through here and then way back to like SYR to ART to YUL.

It shows it slightly warmer on WSI maps..like low to mid 30s across a lot of the interior except up by BML...but the 2m temps are irrelevant anyway this far out. If you have good VVs with an isothermal mid-level profile near -1C...interior would probably have near 32F temps...maybe 30F or so in the higher spots.

You can see on the GFS just how earlier that occurs. Too late for us, I'm afraid.

Dynamic Tropopause dips below 500mb off the NC coast then gradually rises as the PV anomaly moves toward us.

You'd rather see that tropopause fold go to town off BID... not HSE.

Oh yeah I'm just talking about the evolution of it. It's sort of matured in terms of PV interaction over our area, but it's got a low tropopause that interacts just in time for strong WAA to rip west on those Utah state maps.

Yeah it just goes to town/phases too early so you wind up displacing the best dynamic cooling way west.

Definitely... wasn't referring directly to your post just in general.

The storm really does wrap up fast... impressive LLJ.

I think it's important to figure out more than just track. These early/late season storms depend on the exact timing of the phase which will maximize lift and dynamic cooling.

Anytime I see models phase too early I become skeptical. I know the models were spot on with Sandy regarding the phasing but just b/c they were spot on with that doesn't necessarily translate to them being spot on with this system. This will be interesting.

Oh I thought you were referring to the storm becoming a bit warm core. That said, that kind of pressure is pretty typical for a 96-108H GGEM forecast.

Well I do not know about typical but I get your point. Unfortunately this is evolving badly for NJ barrier beach areas. We will have to watch now is timing of phase and occlusion. evolution rings a bell but I am holding off saying what because I know some are being careful and downplaying until Monday.

An early phase is fine when you have a strong high to the north and it's late enough in the season.

These early and late season storms are Goldilocks storms. The track and timing needs to be just right. No wiggle room like you have in DJFM.

I feel like we see 960-970mb bombs on teh GGEM with a fair amount of regularity in the weenie time frame.

It's when the GFS and Euro show something in that range is when it really gets my attention.

At this point I expect zero flakes here, just hoping to get a good storm out of it. I buy the low pressures being spit out by guidance, but the track is certainly not locked.

It would be nice to see this bomb over the benchmark. Phil would be sniffing ozone and blown into Cape Cod Bay while Rev and I rip S+. That will take a lot of work and definitely isn't the most likely situation but worth watching for lol.

Yeah true.

I wouldn't completely rule out or be shocked if we ended up seeing a later phase than what's being shown but as far as accumulating snowfall potential goes outside of the higher elevations across interior New England I'm pretty doubtful now. I would like to at least see one of the Euro or GFS show accumulating snows here but if it's not happening now I doubt it happens.

I like your goldilocks analogy. If the low bombs near the BM it could flip to a 32 paste job for higher terrain but it certainly is a fine line we are dealing with.

Yeah it's just one of those things where if you're in winter you can have a lot go wrong. An "OK" but not perfect track and an early phase when you don't need monster UVM to cool the mid levels... they're already cool enough.

A GGEM kind of storm where it's bombing near the BM is perfect.

A GFS/Euro where the low is holding its own or filling south of us is meh.
