11/6/2016 8:00 AM 0.21 M M M M We set the clock back to standard time, which means that the observation period was actually 25 hours. Conveniently, there was no rain around the observation time, so the 24 hour observation period (to 8:00 AM MDT - which is now 7:00 AM MST) is the same.

For both gauges, we removed the funnel and smaller inner gauge for this storm. The snow accumulated on the rims to make snow cylinders about 3" high. The inner diameter of each snow cylinder was 1.5" to 2", blocking some of the additional snowfall from entering the gauge. Here is our we made the measurements. For Gauge #1, we brushed the cylinder of snow into the gauge. For Gauge #2, we brushed it outside the gauge. Gauge #1 reads 0.58". Gauge #2 reads 0.49". The average is o.535", and this is the number we entered (rounded to the nearest 0.01")

Winds were moderately gusty. There was hail for about five minutes around 2pm -- diameters ranged between 1/4" and 3/8". Light to moderately heavy rain continued through the afternoon. More hail for about 5 minutes around 6pm. This hail had an even distribution of diameters ranging from 1/8" to 1/2". These hailstones were smooth and hard.
