Following up on my whine about not enough snow this winter, and too much rain, Tom Skilling writes:
Chicago received a hefty 3.84 inches of precipitation (water content) from Thanksgiving through January 2, almost all of it falling as rain. With temperatures around 30 degrees, the typical conversion from water equivalent precipitation to snow is about 10:1, so the 3.84 inches would convert to 36-40 inches of snow.
That is about as much as Chicago receives in an average winter. In a colder environment — with temperatures in the lower 20s — the water-to-snow ratio increases to about 15:1. That would theoretically yield between 55 and 60 inches of snow.

Now, four to five feet of snow would be enough snow that I’d be whining about summer instead…
