Must’ve either been steady again thru the night or another strong wave to catch another .03” by observation time this morning. How welcome this all is! Never saw it turn to snow, unless that happened while I was sleeping. |

| Rain continues at time of reading. Temperature is 36 degrees F. Mixed in rain is tiny preformed snow flakes that are not accumulating. Rain essentially has fallen continuously for 24 hours. Did not freeze overnight. Low recorded overnight temperature was 34 degrees F.
Yard - especially large Colorado spruces - appear to be enjoying this type of rain.
Almost feels like the calendar is one month off. More like April or even late March weather. |
