I hope the nam and srefs are right with this...but either way it will be nice to see some snow in the air even if I don't pick up accumulation.

FWIW HRRR doesn't have much of anything...but I'm not sure how it does in this type of set-up.

My area up to your area isn't getting more than flurries.. This is an exclusive far eastern New Eng event

Are you getting emotionally invested in your backyard over an inverted trough? Never a good idea.

Someone will get lucky, we just don't know who yet...but never count on it IYBY. Further east and northeast is usually favored in these...but some OES component may give a boost to the south shore and the Cape.

i'm just wondering what your confidence is in wide spread coatings with 2-3 in a localized area from S coast to SNH? i.e bust potential with this ...thing.

I'm pretty confident most people will have light snow and snow showers in E MA and the interior, esp N of the pike...2-3" amounts I'm not as confident in but I do think someone will get it...just not sure if it will end up in a 25-30 mile long stripe or just a spot amount or two.

Some models develop this a bit sooner than others...Euro waits until nearly morning to really get anything heavier going though it would probably put down a coating to an inch in a lot of areas overnight in the interior.

Meso models usually have the right idea in terms of showing a narrow, but potent area of precip, but obviously if it is off by 20 miles or so..that's a big deal for someone living within or outside that band. I like the idea of this being areas of snow showers with a narrow band producing mdt to possibly hvy snow briefly. It may become a little more widespread along coastal areas as the trough moves in and offshore...all the while cold ne winds develop. That may cause areas of light snow or bands of heavier snow showers to come in off the water late tonight and tomorow. At that point, probably favors more se MA in classic OES fashion. I still think this seems more srn NH on down into ne MA and maybe up into ext srn ME.

Nice 30dbz band moving through 10pm-1am...is it true they're getting rid of the RUC?

I haven't heard....this image is only through 06z...but you can see the nice band and where its setting up for several hours

RUC actually closes off H7 at 12z tomorrow overhead. At 850mb, you can see that cool isotherm structure with cold air moving east to the south of the 850 track and weak WAA to the north. Right in that transition zone is where you'll have some frontogenesis and that band of heavier snow.

We'll have to watch for that late bloomer type action that the RUC and HRRR don't go out far enough to see...RUC sort of sees it by 18 hours, but those models beyond 6 or 8 hours are quite unreliable...the closing off at H7 and H85 are a definite signal for some enhancement over E MA/SE NH

Given the ULL track, I could see areas from central VT and NH into srn ME maybe getting more general synoptic lighter snows. That would make sense north of the track. However, closer to the ULL itself, the more heavier band of snow may lie thanks to stronger low level convergence. So, the screw potential is higher across SNE since we may not see the more widespread lighter snows that parts of CNE may get...but the opportunity to cash in is there.

2" is cashing in?

The RUC is being replaced by the RAP. Essentially the same thing, although they will be adding one domain that will be larger than the current RUC domain. Otherwise the RAP will have the same set of data that the RUC had.

The switchover is supposed to happen on March 20th, with the 12z run.

Seems like it's continuing to shift North up into NH and Maine.

LOL, anything for you not to lose your bet :lol:

Thanks for the info.
