It also affected accumulation in the gauge; depth in the cylinder was about half of what was found out in the yard.

Total snow depth on my property varied from about 5 inches to about 8 inches; I avoided obvious drifts which were deeper. Overnight low was +1.8F at 7:44 a.m.MDT.

It was snowing lightly at observation time. Wind was strong enough at the height of the storm (13mph with gusts to 22mph between 3:00 a.m. and 5:00 a.m.) to create 17" drifts, yet it scoured other areas to a depth of only 5.5." It was impossible to get a definitive snow depth, but I made many measurements to decide on an "average" (9.5"). Snow is melting in my cylinder, so I measured its weight to report melted snow amount (0.76"). I'll revise this report later if it changes. *** The core sample was obtained at 1:10 p.m. (NOT observation time) but not reported until 11:55 p.m. after the snow in the tube had melted. ***

The winds were fierce with gusts topping 61 mph at my weather station at 3:54 p.m. Twenty minutes later, it was over. With such high winds I doubt the gauge could catch all the rainfall. (However, my weather station's gauge, colocated with my CoCoRaHS gauge, measured 0.11".) The temperature before the storm hit was 83F, and, 5 minutes later, had dropped 21 degrees to 62F!

Less than 5 minutes later all precip ended. (The weather station's total rainfall was 1.27", a bit less than my colocated CoCoRaHS gauge.) Peak wind gust was 39 mph at 8:45 p.m., and the 5-mintue average wind speeds between 8:35 and 9:15 p.m. were between 13 and 22 mph.
