Heavy snow in the afternoon. I checked the roof after the snow ended and it had almost no snow on it (it was very windy and cold, so it must have blown right off). We would have been able to open, but the air was too humid all night and the sky was cloudy until about an hour before the start of astronomical twilight. The observers were Jean Quashnock and Dan VandenBerk for UC03, and Don Hoard for UW07.
