| This is the 2nd highest one day precipitation report this year (other was 0.35 on 3/7) and all of it fell in about half an hour as we caught the core of a thunderstorm from 1255-1330. There was some very mushy small hail (seemed like wet snow at times) that briefly accumulated a slush layer for a short time. Otherwise, there was no other precip. Cloudy and foggy this morning with a temp of 41 after a low of 37.2 |

| Sunday - morning was very damp and cold. High reached only about 50 in late afternoon. Rain, some lightening and thunder began after noon and continued about 1.5 hours but somewhat disappointing rain in gauge. Rained sometime during the night (.01" in gauge this am after emptied yesterday after the rain ended). High percentage chance of rain today through Thursday - temps upper 50s to mid 60s. First year my Boulder Raspberry bush flowered. Seems so odd given how we are in a drought and had little snow and rain since October 1st. |

| Intermittent storm had rain, soft hail or graupel and even a couple flakes. I was away from home and could not file a timely hail report. Not much moisture, but it did knock the dust down. Also, gauge catch might be lower than actual, due to high winds, especially after the storm. |
