| Temperatures ranged from 32-39F all day long. A very wet heavy snow you'd expect in late spring not at this time of year. Snowpack is more akin to 'slushpack' with a good bit of settling, compaction reducing depth but still a very high moisture content. Snow fell all day long. With very heavy rates for most of the day. |
