Snowfall
We report snowfall in liquid-equivalent terms.The actual depth of new snowfall is typically between 5 and 10 times the
liquid-equivalent amount, assuming the ground is frozen.Colder, drier snow tends to be on the higher end of that range
and warmer, wetter snow on the lower end.
As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year.
Leadville experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 8.6 months, from September 17 to June 5, with a sliding 31-day liquid-equivalent
