Observation Date Observation Time Precipitation Snowfall Snowfall SWE Snow Depth Snow SWE Notes
7/20/2012 7:00 AM 0.59 M M M M Rain was falling at OB time. Even a strike of lightning when I picked up the gauge. All rain measured fell overnight.
7/21/2012 7:00 AM 2.37 M M M M The rain came in three phases: First was at observation time yesterday, it rained for another 30 minutes or so, albeit didn't produce much. Second, a strong storm dumped .92" just after 1pm. Then, a very slow-moving storm passed through between 10pm - midnight. This storm produced a tremendous amount of lightning, and some nearby roads were flooded. To my knowledge, no more rain fell overnight, or at least I didn't wake up for it.
7/22/2012 7:00 AM 0.01 M M M M It appears the rain barely missed this location. We did get a few sprinkles early in the observation period.
