Even in this winter, he had 137". That's 2K for ya...right in the upslope area too.

That sounds about right for 2000ft in the upslope region. I had a similar number near 140" at 1500ft in Stowe at the base of the ski area.

I've always wondered about the snowfall up there...gotta be close to the Northern Greens upslope but I rarely see big statements out of GYX in that area during upslope events. I gotta imagine when we are under Winter Storm Warnings for upslope that they'd be getting a similar amount in Coos County.

It's really an observational wasteland up there for us, because HIE and BML aren't really favorable for good upslope snows. More like the 8SM -SN type stuff. Occasionally, BML will get into a heavier SHSN.

Ahh and this answers my previous post about why we don't see as many warnings for upslope as we do in VT despite what appears to be similar snowfall totals.

Granted the population in VT's upslope is much more dense and reports are very easy to come by...plus the state's major interstate (I89) runs right through the upslope region between BTV and Montpelier.

We need to get spotters/COOPs in the right locations. Pinkham is on the wrong side of the spine, and First Conn Lake is about all we have.

I actually would like to issue more warnings for upslope in those areas personally, there are times we know it is likely meeting criteria. We just get very little in the way of verification. Though more than a few people use that website to gauge snowfall in northern Coos.

We do have some very detailed studies done on upslope, it's just a matter of using them.

That's about right PF. I wonder if they are a bit colder temp wise though. I feel like they are first in line to be slammed by arctic airmasses.

Chris, you've seen that sight before I guess?

I haven't actually, but I would love to see that part of the state. I might try and tag along for one of the spring snow core surveys or something of that ilk to get a chance to see it. Though a little vacation up that way wouldn't be the worst thing in the world.

Any of these studies online? I've seen a few from BTV's area but would be fascinated to read anything from GYX's FA...never known much about NH and ME upslope though the bulk of it inthat area probably falls just over the border in the Eastern Townships.

Yeah the region from your area up into nrn NH and even the crown of ME have great mesoscale upslope areas. Always cool stuff to see.

It appears it made it to ER as a tech attachment, so yes.

That should work for everybody. I assume that it's more of the same for you, except that wind direction will be a major difference in the big snows for the Greens vs. the Whites.

Cool thanks! I'll take a look at this when I get home tonight. I'd assume a north wind is better there whereas here that flow doesn't do much for us...flurries and light snow. We definitely need more westerly component.

my grandfathers house in baldwin mills quebec always gets nailed you can take a 20 minute drive to coaticook and there is much less there it amazes me sometimes

We can do okay on a west wind up there, but the Greens rob a lot of the deeper low level moisture so that we are generally advisory or less when you're piling up.

Yeah but I gotta imagine that those areas get destroyed during the backlash period of synoptic events when we get those vertically stacked systems up near FVE, and left with a moist cyclonic flow for like a day or so. They'd be closer than we are to the deeper moisture feed from the Maritimes...almost like a lingering deform band that gets enhanced in a big way by the terrain.

It's true, while the coast and interior can have a pretty quick off switch once the winds go NW, those mountains will continue to pound.

It is sometimes difficult to grasp in the nowcast periods because all the ASOSs may be 10SM or MVFR at worst. So you almost have to calibrate if BML is 5SM -SN then Pittsburgh is 1/2SM or worse.

In winter i ride close to that area and the snowpack is usually quite impressive, You don't want to step to far off trail..

I have a neighbor from back home in RI that rides up there too, and we were discussing how little we have in the way of weather knowledge up that way. Turns out we both use that website to find out snowfall and snow pack information. I thought that overlap was pretty funny.

Well, Its tough with no observers in that area so that is a handy site, I bookmarked it, But riding out by Kennebago and out towards Bosebuck, I have seen quite a few NH riders that came over from the Pittsburg area of NH there always seems to be an abundance of snow throughout that area and i know most times i am up there we are in squalls quite often

Yeah that's a big part of making it seem so wintery in the upslope regions and really pads the snowfall totals when you get daily 1-3" snows from squalls and snow showers.

I'm sure it's the same up there as it is here, but I've run my numbers for the mountain and on any given day in Dec and Jan, there's a 70-80% chance of at least a dusting/trace of snow. Even here in town we typically have 20 days out of January with measurable snowfall...I think 2011 in January it was 26 days with measurable (granted in town that means a lot of 0.1-1.0") snow.

For whatever reason the chances for snow drop off in Feb and March, as we don't seem to get the frequency of the dark/cold months of Dec/Jan and I wonder why that is. But snow showers and squalls are sort of a way of life all along the NW flank of the Apps.

I would bet though if you just forecast likely POPs everyday day in Dec and Jan you'd come out to being pretty close to correct by the number of days with at least flakes in the air.

Yeah PF, You are right, You could forecast a percentage of POP's dailey as i see all to often, There are not many days in that area where i don't see flurries or squalls when riding, Also when riding in some of the higher elevation areas i can deal with ryme ice as well, That is more of a PITA then the constant Lt snow
