#Mar. 2: There is much uncertainty as to what the Precipitation was because the blowing and drifting snow
         up until 9 AM prevented capturing most of the snow (whatever amount it was) in the Rain Collector.
*Nov. 21: 1.5" Snowfall only registered .01" which is too low.

HIGHEST Rain Rate: 1.24" per hour on August 14th @ 0340


				Snowfall (in) - Current through 2020 hrs. of day before date shown at top
