Total Frozen Precip. Inches | Total Melted Precip. Inches | Temp. °F | The snow amount shown on the snowboard will differ from the averaged observed amt. particularly if it is windy ! - - - Remarks for the Time Period | |
| 0 | 0615 hrs. | T | T | 33.7 | Very light snowfall rate at the currently. | |
| 1 | 0700 hrs. | 0.02 | 0.01 | 32.7 | The lawn is starting to get white and the temperature has dropped during the past hour. Snow is melting as it falls on cement walks and streets. Snow is fluffy aggregate crystals trapping air but contain little moisture. | |
| 2 | 0800 hrs. | 1.2 | 0.6 | 32.7 | During this past hour very large aggregates or fluffy assemblages of many crystals now leaves an uneven snow surface and more air spaces in the snow and increases the snow to water ratio to about 20 to 1. Currently the snowfall intensity has decreased significantly and the flake have become small and the snow is still melting as it falls on cement walks and streets. | |
| 3 | 0900 hrs. | 1.6 | 0.8 | 32.8 | Snowfall intensity has decreased to a very light rate. At this rate melting is about equal to the snowfall rate. Snow surface since 0800 observation has become very uneven varying from 1.8 inches to 1.4 inches on the snow boards. | |
| 4 | 1000 hrs. | 1.7 | 0.10 | 33.2 | Only a slight accumulation during the past hour of 0.1 inches. We are near the end of the snowfall as seen on the radar. The temperature has also increased this past hour 0.4 °F and melting is occurring. | |
| 5 | 1100 hrs. | 1.4 | 0.10 | 34.1 | We have lost 0.3 inches in the past hour as the temperature has increased 0.9 °F and only a few flurries in the past hour. It now looks like some additional snow may occur from what is call the wrap-around-effect. | |
| 6 | 1200 hrs. | 1.5 | 0.14 | 33.1 | We have added 0.1 inches to the total this past hour on the snow boards. The lost is greater on the warm ground but it is interesting that the temperature has now dropped 1.0 °F this past hour. | |
| 7 | 1300 hrs. | 1.7 | 0.20 | 34.1 | We have added 0.2 inches to the total this past hour on the snow boards from the 1.5 inches at 12:00 noon. The temperature has increased again and we are at the back edge of the snow of the wrap-around-effect as seen on the radar so this snow event is over except for a few snow flurries. | |
