Other Tidbits about snow to liquid ratios
The fluffiest snows (high snow to liquid ratios) usually occur with light winds and temperatures near 15oF(-9.5oC).
At colder temperatures crystal type and size change,
- at very cold temperatures crystals tend to be smaller so they pack closer together as they accumulate producing snow that may have a ratio of 10 to 1 (sometimes even lower.)
A study by Mote (1991) found that ratios for Omaha, Nebraska averaged around 14 to 15 to 1 during the period Dec-Feb. and found that the highest ratios occurred with lighter snow events and the lower ratios with the very heaviest snowfall. The heaviest storms had a 11-1 ratio.
