It'll be interesting so see how your area does on those sneaky NW flow uplsope events. I'm guessing pretty well. Its Pittsburg's bread and butter. I'm sure your location is better synoptocally, but they do really well on the surprise 6-12"+ powderfreak specials. The type of pattern where every fropa drops 3-6"+ 1 Link to comment Share on other sites More sharing options...

Unless you cleared and added the total to it, I think it could’ve snowed up to another 10” but only added a couple inches to the depth. I think at 40” you probably only add an inch of depth if the snow rate is 3”/hr. That’s extremely hard to maintain. Even if snowfall tapered to 1-2”/hr there might have actually been no gain or even settlement. Just an amazing high-end event. The fact that there was 24-30” on the ground and gaining 6” per hour in snow depth is incredible to me. Usually at 24” stuff starts to compress... but to stomp on the gas at that point up into the 40s for snow depth is insane. I was pretty surprised to find 32" depth at 11am on Friday almost a full 24 hours after the heavy heavy stuff stopped in East Dorset. Pretty amazing that the 24hr state record could have also been in East Dorset at 730ft in the Valley if there had been an official observer or someone who cleared just once. Imagine the state record for VT being held in a somewhat snowhole above Jay, Stowe, Stratton, etc? 50 years from now weenies looking and saying how the hell is East Dorset the 24 hour record holder...lol. What could have been. Ha Link to comment Share on other sites More sharing options...
PhineasC Posted December 20, 2020 Share Posted December 20, 2020 Decent upslope signal appearing on the models for the midweek period before the tropical rains. 00z RGEM looks pretty good as a signal. Link to comment Share on other sites More sharing options...
powderfreak Posted December 20, 2020 Share Posted December 20, 2020 Crazy strong inversion this morning. I had 15F at my house, 20F at 1500ft at the office... but snowmaking was shut down due to temps. 20F in the parking lot and no snowmaking?! 30F at mid-Mtn and 31F summit. Every morning per tramway code we need to run all auxiliary power on the lifts, so the Gondolas back up diesel motors pump out some blue smoke when they start up... check out the visual representation of the low inversion just above the base area by the horizontal smoke layer. 1 Link to comment Share on other sites More sharing options...

Would be nice to see more than one run of more than one model but it’s a start. How a system like that one is going to play out for someone in your location is often night and day compared to what happens along the coast of SNE; for a spot like Jay Peak, we’re not even talking in the realm of miracles for a decent outcome. It’s essentially the counterpoint to what went on during Winter Storm Gail in the Jay Peak area – while that type of an event is sort of a one-off/occasional thing, the look of the next week is more of a typical winter reality result. There are actually four potential snow events in the next week though (today, Tue/Wed, Fri, and Sat/Sun), and that’s a pretty respectable pace, even for the Northern Greens. 1 Link to comment Share on other sites More sharing options...

dendrite Posted December 20, 2020 Share Posted December 20, 2020 Yeah I’ve had a few in that 18-21” range since 2006, but nothing over that. I’m assuming he didn’t get back to the early 2000s yet though since this area did well in a few events back then. Now my record daily snowfall is higher than ORH’s and my greatest storm is only 0.1” less. Link to comment Share on other sites More sharing options...

Now my record daily snowfall is higher than ORH’s and my greatest storm is only 0.1” less. I am not a good record keeper but it seems I get "stuck" in the 12-14" range for big events. Maybe cause the down sloping from a north or northeast wind with the Whites in that general direction. Perhaps because this storm was not deep and didn't have a strong wind that helped somewhat? Although I had the lowest visibilities I have ever had with a synoptic event I wish I was just 10 miles further south to see the true "deathband" rates. Another thing I noticed when it was snowing at the 3-4" rates was that it just looked like fog outside. So many flakes falling it was hard to discern the individual flakes unless you had a dark backdrop no more than 5 or 10 feet away. 1 Link to comment Share on other sites More sharing options...

J.Spin Posted December 20, 2020 Share Posted December 20, 2020 Event totals: 0.8” Snow/0.06” L.E. We had radar echoes overhead for quite a while this afternoon here at our site, but it took a while for snow to actually present itself visually, presumably due to required moistening in the atmosphere. Once it did get going, the snowfall rate was pretty heavy there for a bit, with flakes up to ¾” with a mix of other flake sizes. As of the 6:00 P.M. observations time, the snowfall rate had tapered back to something lighter however. Details from the 6:00 P.M. Waterbury observations: New Snow: 0.8 inches New Liquid: 0.06 inches Snow/Water Ratio: 13.3 Snow Density: 7.5% H2O Temperature: 26.2 F Sky: Light Snow (1 to 4 mm flakes) Snow at the stake: 4.5 inches Link to comment Share on other sites More sharing options...

That was another storm with a band of 18-24"+. That map does show the mean storm vector though, ha. New England is swaths of SSW to NNE direction bands of big totals.

wxeyeNH Posted December 21, 2020 Author Share Posted December 21, 2020 29F In the fog with dim sunshine. Snowstake down to 13". Not expecting this 12 hour thaw into the 40's with an inch of rain to melt the pack, just turn it into a glacier. Good for the turkeys but bad for the deer as they can't run through glaciated stuff and the coyotes can outrun them. Link to comment Share on other sites More sharing options...
