Fluffy snows are expected today and tonight, producing accumulations with very little water. Commonly, the percentage of water to snow is called the "snow ratio". An old rule of thumb was that for every 10 inches of snow, there would be 1 inch of water (10:1). However, this is far from the norm, and recent studies indicate that a 12:1 ratio might be more representative (on average) for the Upper Midwest. This said, there are so many variables that can affect the ratio of liquid water to snow that using a rule of thumb is usually off the mark. In fact, the snow ratios can change dramatically within a snow event itself. Some of the variables that come into play include...
With the very cold air in place across the region at this time, snow ratios today and tonight closer to 20 to 1 are expected, athough they could be higher.
