| Snowpack is limited to raised surfaces. gravel roads, concrete surfaces and flagstone are snow free. Snow stopped at 6:30 while I checked the gauge and patches of blue sky were overhead. Catch had the funnel and inner cylinder in place. careful manipulation of the "muffin top" put all snow into the 4" container where I weighed it. Snowfall began at 8:05 pm on the 19th and was still snowing at 10:00pm (COR: changed time snow began from 6:30pm to 8:05pm based on scribbled notes taken last night) |
