TotalSnowDepth: 21.0
NewSnowDepth: 24.4
Notes: Ob at 945 pm, temp was down to 25, wind quite light now with S--. Another 2.5" since 500pm, very light in weigh. Snow has not accumulated much at all since ~8pm. A real variable SLR. Ranged from 7.7:1 for yesterday, rising to 10:1 last evening but then falling to 7.6:1 for the snow overnight.
My SLR improved to 10:1 for the period 0700-noon, then from noon to about 8pm it was snowing, mainly S+ with big flakes from a little before no0n until 945pm lots of heavy snow with big flakes = 11.5" accumulation with 0.42 melted gives an SLR of 27:1. The 24.4" total makes it my 4th biggest storm (records east of Boulder since 1980), barely edging out the Oct 1997 storm.

NewSnowDepth: 6.0
Notes: The 0.27 precip is just the amount in the gauge since the last measurement at 3:45. The snow has almost stopped falling. The wind has died to nothing. The new snow and total snow are best ideas based on several measurements because there was a lot of drifting this afternoon. I cleared 3 spots each time I measured to try to find a location that would give me a more true reading of the new snow that fell between each measurement. I ended up taking an average of the three, but only to a whole number. The same is true for the total snow. I will put on snowshoes in the morning and take more measurements of the totals to get a better measurement of totals. For now, it looks like 42" is about right overall. Crazy!
