About half an inch of snow and 28 below at 8am on Keystone Ridge. Here's how it snows at these cold temperatures. The morning sounding shows the deep cold air (-30C and colder) is about 400 meters thick. The snow producing clouds have a temperature around -20C to -23C. This is reflected in the sand-like consistency of the snow this morning.
So what sort of snow ratio's did this produce? It seems like they were usually around 10:1 in this kind of situation if I remember correctly.

Matthew,
ReplyDeletefrom the RTP this morning, the ratios were 10-1 or a bit lower. Pretty standard for this set-up, though I was expecting the warm air to make it a bit lower and was quite surprised to get up this morning and see it 28 below here on the ridge. Caribou Peak did get to 4 below before cooling off again.

Ok, sounds like what I was thinking. Thanks.
