Start Date End Date & Time Duration in Days Precipitation Snow Depth Snow Depth SWE Notes
2/22/2019 2/23/2019 7:00 AM 2 M 40.0 M There was far too much snow during this three day period to register in the gauge. It accumulated about 40 inches at our house over the three day period. Thursday's snowfall was the calendar day record but the storm is nowhere near the record. The southwest side of town, nearer to the rim, got a foot more than we did.
3/10/2019 3/13/2019 6:00 PM 4 0.96 5.5 M Over two and a half days we had heavy rain, hail then snow, in that order!
