Wouldn't it be nice if this was one of those deals where they forcast a foot, but the storm moves slower then they thought and we get a monster 2 feet + pounding? I know I'm being greedy, but just sayin.

wow, fantastic post powderfreak, thanks for sharing!

hmm after looking at the latest models im a little worried because im going to be at sugarloaf monday, it looks like things are going to come in waves, and most of the precip mainly stays south of sugarloaf until monday night?? or maybe i have no idea what im talking about! thoughts...

National Weather Service Gray Me
352 Pm Est Fri Jan 12 2007

...a Wintry Mix Of Precipitation Is Expected Sunday And
Monday...

A Cold Front Will Cross Maine And New Hampshire On Saturday...and
Then Stall Over Southern New England Saturday Night. A Wave Of Low
Pressure Will Move East Along This Front On Sunday...briefly
Lifting It North Into Southern Maine And New Hampshire. This Area
Of Low Pressure Pressure Will Likely Produce Intermittent Light
Precipitation On Sunday. Temperatures Will Be Around The Freezing
Mark Across Southern New Hampshire And Southwestern Maine...where
The Precipitation Could Fall As Freezing Rain...rain Or Snow.
Across The Mountains...snow Showers Are Expected For Sunday Afternoon.

Sunday Night...colder Air Will Drop South Into Northern New
England...and Any Mixed Precipitation Will Change To Snow
Overnight...although A Snow And Sleet Mix Is Possible Along The
Coast. The Snow Will Continue Through Monday Night...with The
Greatest Snowfall Accumulations Expected Across Southern New
Hampshire...southwestern Maine And The Mid Coast...where Six
Inches Or More Of Snow Is Possible. Snowfall Totals Will Likely
Decrease As You Head North Across Maine And New Hampshire...with
Only A Few Inches Expected In The Mountains.

NWS @ Gray, ME - Following the trend of the storm heading south
NWS @ Burlington, VT - Still expecting northern areas to get heavy snows

EXCUSE ME MODS.....AHEM.......I think with the bad weather we've been experiencing this winter we should refrain from "storm discussion" threads as they only have the potential to piss off Ullr.

I suggest for the remainder of the current season we put a "ban" on "storm discussion" threads...

Thank you for your anticipated cooperation in this VERY sensitive matter...

Or worse, as we've seen over the last fifteen months, where they predict big snows and it turns out to be either nothing or NCP. This one is starting to look like the real deal. We should know for sure by tomorrow.

[Big Game]

Yep. Putting the snows on tomorrow.

Still uncertainty in the models and one thing I've had in the back of my head is that the European model has been keeping the system further north than the American models this entire time. It has trended slightly further south than it was 2 days ago, but it keeps the axis of heaviest snows north of where the GFS and NAM have it. The Euro was correct on the Dec 26 bust of mine when I followed the American models fully, and I really don't think the GFS's current scenario makes sense with the limited precipitation to the north. I'm sticking with 6" all the way to the US/Canadian border at this time and I believe the uncertainty with the max snow zone possibly making a last minute move to the north is why BTV still thinks its entire area will receive heavy snow. Needless to say, the American models are the furthest south with this system so I cannot see it going further south than where they have it now.

I like a blend of the NAM and EURO which targets the heaviest snow across central NY, central VT, up through Sunday River. Sugarloaf, Jay Peak, Stowe and Smuggs will likely be on the northern side of the precip but remember, the air will be colder, there will be little to no mixing of precip types, and ratios will be higher. I do think we see an enhanced band north of the main precip zone, as we usually see in these events, and it often follows the -10C isotherm at 850mb. This is usually where the best snow growth zone is and if it comes together there's the chance that we have the main area of max snowfall run from say Gore Mountain, NY to Killington/Sugarbush region in VT, and across central NH...just north of that we have a drop off in snowfall but then north of that, we have a quasi-deformation band that enhances snowfall even though liquid equivalents are lower...north of that band (say just north of the Canadian border), snowfall amounts drop off drastically in a very small spatial distance.

Hope that makes sense, I'm going to have a final forecast out tomorrow afternoon or early evening...roughly 48 hours is what I like for a final forecast product but I'll be skiing at least through noon tomorrow. When I get back I'll put out the final product with accumulations map and all.

say, uh, boss, I'm not feeling so well. The weather doesn't look none too good for drivin'....
Well, I'll just lay low and drink a lot of fluids.
