Thus, SWE of snow = 0.62" plus rain of 0.07" = 0.69" total precip for the day. Snow depth was 4.5 inches. RDJ

4/6/2010 7:00 AM Hail started about 7 am and ended by 7:10 am (it might have started a few minutes before 7 am). I estimated hail was 0.02" after it melted. I checked the gage at 7:10 am and the storm was to the east (Denver) with mostly clear skies at gage location. The hail depth on the ground was estimated but basically it was one hailstone diameter (0.1 inches) in depth. Soft hail had metled by 8:30 am except on north facing slopes. Also, see precipitation report for April 6th. RDJ Rice Rice Rice Soft 10 2min no damage Continuous False After rain Same time as smaller hail vertical 0.1
