yeah, excuse my IMBY'ing but with a high in the upper 20s and with .75-1" QPF it's hard to believe we won't end up with nearly a foot.

Its all going to depend on the snow growth....I've had 18 to 1 ratios with a temp near 30F and 8 to 1 ratios with a temp of 20F.

Yea, I liked the 06z run better.

This is 2004-05, displaced about 30-40 miles to the NNW......Brockton winter as opposed to Carver.

I don't see a screw zone like the last storm. In fact, I think you could be in a decent spot for banding potential. I know meso screw zones can happen, but imo you seem in better shape for this storm, although you did eek out 12".

CON get about 0.70-0.75"

Thanks Will

Split the difference or so I guess: ~0.75. The NAM has 0.75" for CON and the GFS is 0.61". So I think we're honing in. I'd say 6-10" looks good.

Sounds good, I would love 6+.

hopefully this storm won't involve those snow pellets (though we're not dealing with a parcel of warm air aloft to such a great degree) and those tiny flakes (in the last blizzard) that take forever to stack up...any insight into this?

Is that something that's difficult to forecast? Say I were to google it to try to learn...would I google "dendritic growth"?

There is much more to it than your surface temp.

Thanks, still trying to soak this stuff up.

Snow growth should be much better in this system for most as we have deeper saturation and better lift at pretty much all levels for most of the storm. Last storm worked in some drier air above 700mb for a time, and the overall lift wasn't as intense as this system looks to have.

I wonder who gets blizzard warnings...maybe Plymouth, Barnstable, Bristol Counties in MA and Newport and Washington in RI?

I was looking att the Blizzard Product on the HPC site and it was based of the 09z SREF's Looked like the Cape and Islands and maybe extreme coastal Plymouth up to Scituate made it into any type of blizzard %'s.

I don't think Spfld area has had a storm over 10" since 07/08, correct?

Springfield has not had a true double digit storm since the feb 06 storm that produced anywhwere from ten to twenty inches from nw to e/se over the spfd area but if you go back to a true area wide event of well over a foot its presidents day 03 storm.

You'll find a lot of PP and PDF documents on it. I think this storm will have good snowgrowth for most.

Another disaster for N. Maine.

All winter snow is being wasted on dilletantes who think snow's purpose is to be sculpted in to perfect snowbanks.

Suburban and city tyros who squeal delightedly when their snow cancels classes at the community college nearby.

Snow is lifes blood up here. Thousands of businesses are dependent upon it for their sustenance and it has not appeared at all.

An unprecedented economic disaster is unfolding up here in N. Maine. True hardship is upon us here because of this horrible pattern.

S. New England's snow is squandered there. It's a decorative nuisance. An embellishment for bus route weenies. Lack of snow for them is psychic pain only.

No snow for us is economic disaster. Your celebrations in S. New England are as thoughtless as your snow is pointless.

I write this as an ex-Cape Codder/Westonian.

Tough sh**.

Upton's most recent write-up calls for 6"-12".

good call for right now just in case things go not as planned the low end covers that,also wonder if we go to warnings at 5pm and do I dare ask? any Blizzard warnings for some?

FWIW there is a 100% saturation contour at H7 along the ma/ri/ct border extending into srn VT and NH at hr 48. This is why I think GC and srn NH and the srn tip of ME could do pretty well, despite what qpf says.

I feel for those up there who depends on snow...but I'm not going to apologize for a phenomenon that I have no control over. The whole weather "morals" thing is a tired argument on the forums going back years.

I'm not complaining...just expressing an opinion.

I will not get over a foot if the cf never makes it out of Boston and away from the immediate N shore.

This is a rule of thumb that I have recently began to implement after years of observation, here.

I'm sure you can look through the Kocin book and find exceptions, but it works more often than not.

Jan 2005 was an exception, but that event was not of a normal scale.

LOL at Ray

I am going to be one greedy muther****a with this storm. I want to be in the jackpot and I feel pretty confident about that right now. Screw everybody else.

I doubt they'll hoist blizzard warnings.

its get some decent signals...big 1045 mb higher over the plains...980-985 mb low just inside the benchmark...rapid deepening inducing a strong isallaboric component. We'll see I guess. I think some coastal areas should have them.
