This includes the squalls on Thursday

I missed that too, thanks.

I honestly am more interested in that arctic front on Thursday.

There’s something aesthetically pleasing about snow squalls and wind ahead of an arctic airmass.  The SW flow out of the Great Lakes region pools moisture ahead of these FROPAs, then the front drags it over the terrain before drying out again.

Looks like a decent early season arctic boundary.

 

That FROPA means business.

Looks like BTV will be ticking up totals for Thursday along the spine if that modeling holds

Oh yeah, I’ve been tracking this quietly. It’s going to get frigid for a bit. Will be interesting to see how we do here.

I find the mesoscale stuff in the northern mountains to be the most interesting type of weather.  

The atmosphere is fluid and Thursday is like watching a shallow ocean wave move over rocks, from NW to SE across the region… the areas with the most churn as the ripple moves through should see the best results in the northeast (the northern terrain).

Winter Storm Bellamy hit parts of the Midwest fairly hard on Saturday to become TWC’s second named storm of the season, and then the system continued its eastward trek and started to affect our area by early Sunday morning. Throughout the day it brought light snow to the area, and by the afternoon we’d picked up about an inch of accumulation in the valley. Coupled with the accumulations from the midweek system, I figured it would be worth a quick ski tour to see how the powder was building up in the higher elevations, so my older son and I headed up to Bolton Valley in the mid to late-afternoon.

We toured on the lower 2/3 of Wilderness and found a general 3 to 4 inches of powder coating the existing base in untracked areas. That seemed about what one might expect based on picking up a couple of inches from each of these past couple of systems, and conditions were actually a bit better than I’d expected because I was worried that the wind might have blow the snow around and left us with little powder to ski. Indeed the snow was fairly light and dry (my liquid analyses from the two storms averaged out to snow in roughly the 5% H2O range for liquid equivalent), so it was nowhere near enough for a resurfacing, but it definitely offered up some nice turns on lower angle terrain. Most turns weren’t bottomless, but you’d get some bottomless turns here and there where the powder had settled in a bit deeper. This was certainly a case where denser snow would have made a huge difference in resurfacing, but there was only so much liquid equivalent with these past couple of systems in this area, so they could only do so much to cover the subsurface.

The next storm in the queue has been named Winter Storm Chan, and it looks like it could add a more substantial shot of snow to the slopes – Winter Storm Warnings and Winter Weather Advisories are up throughout the area. So, on top of the snow that’s already fallen in the past few days, it definitely holds the potential to kick the conditions up another notch.

This BTV update is for this storm only (thanks @Boston Bulldog)

20.2F  Light snow vis  1 mile.  Poor snow growth.  Expecting maybe 7 or 8?

Going on gut 7 inches today in my yard.  I can tell by the snow i did note nws saying ratios might go down but this is dry right now its gonna get fluffy for early dec

Deformation band showing up right over BTV and into Mansfield. Take the over for the Spine?

Radar doesn’t show it, but we’re snowing nicely out here too. Already over a half inch. I’m going to be learning the climo here for a while lol so I’m not sure if deformation bands are a thing here.

What a start Its mirroring 68/69. Another 12 for the week by Friday 

[powderfreak]

6” today at 1500ft.  Tapering off.

Good skiing.
