Only a trace on the ground and in the gauge this am at 7 (22 degrees) and will be cold today and tomorrow - low thirties and low teens overnight. Sun has begun to shine, sky is bluing, birds are feasting and gorgeous glistening AM. |

| Friday was a lovely mostly sunny day with mild temperatures in the 40's. About 7 pm the winds became very strong and about 7:15 pm wind blew in hail or graupel snow. Because of the size it seemed more like hail. Snow followed the first blast of winter weather. Our current temperature is 24 degrees with a cloudy sky, a light breeze, and a flake or two falling from the sky. We need to be measuring snow in feet not inches. At least this morning we look a bit more like November 29, |
