2/22/2019 6:00 PM 1.23 1.5 M M M A rain changing to snow then back to rain event. Rain began last night and there were two moderate intensity events. The time of heaviest precipitation noted below produced a maximum rate-of-fall of .30 inch/hour with the other close at .28 inch/hour. The rain changed to snow this morning around 6:48 am (approximate) just after the cold front passed. It snowed at variable rates nearly all day, and since the temperature stayed above freezing the snow was melting as it fell. Around noon I measured a depth of 1 1/2 inches on exposed surfaces and in the outer 4 inch rain gauge cylinder, which produced a water equivalent of .57 inch. The snow changed back to rain at 2:20 pm and stopped altogether at 4:42 pm. I put the snowfall measurement in the New Snowfall block, but only a trace of snow remains on the ground now at measurement time.

My maximum rainfall rate for the time noted below was 2.15 inch/hour. Also noted a couple wind gusts to 28 mph as the gust front arrived prior to the rain. I also witnessed a trace rainfall event earlier in the period from 2:44 - 2:50 am.
