SNE heat bust today

 

Gotta feel for Kev.  

85F up here.  I feel like we’ve been 85+ more than all of 2016...I think that was the summer it failed to hit 90?  2017 was a torch with like a whole bunch of 90+, but I think it was 2016 when it was a lot of 70s and no 90F.

Yeah other than that one 2-3 day period it’s been more summery SNE than NNE. Way more humid too 

There was like a solid 7-day period in there where 4,000ft up here saw an average temperature higher than the same period at ORH.  

Normally given what we’ve seen so far would translate to like half a dozen 90+ days at BDL already.

Certainly higher dews down there, no question.  We’ve had more of the higher diurnal change heat.  Like this morning was upper 40s to low 50s before an afternoon torch.

No grooming snow mobiles either

Yeah that and zero traffic during the hottest diurnal time of day makes a huge difference.  It’s been incredibly hard to even poach as they’ve had manned security checkpoints to keep folks away from it.  

Its been a good case study of if a ski area made a shit ton of snow and then no one touched it for 2-3 months, how long would it last?

They could just add wood chips and mylar to the top of it like Craftsbury and give snow storage a try.

Next, with the help of the Craftsbury grooming team, they created two test piles at the end of the 2018 season in order to determine an optimal system for insulating snow through the summer. They covered the piles with roughly 25 cm of wood chips which were instrumented with thermometers. They tested a variety of covers including foams of different densities, concrete curing blankets, space blankets, and reflective mylar over the top to deflect solar radiation.

After monitoring the piles through the summer, they identified the optimal setup. On top of the manicured snow pile, a concrete curing blanket was laid primarily to protect the snow from debris. The blanket also adds some insulation. Next, a layer of wet wood chips 20 to 30 cm deep was spread, providing the majority of the pile’s insulation. Finally, a white mylar space was stretched across to reflect thermal energy from the sunlight. This system proved highly effective. 

“When you monitor the temperature underneath that concrete curing blanket, it basically doesn’t change. No matter how hot it is outside, it basically stays at zero.”

With a scientifically-backed storage plan, the UVM and Craftsbury collaborators went into the 2019 season ready to give snow-storage a go.
