Snowmakers don’t abide by any set schedule; they go where they are needed at the mercy of the weather.  One of the newer strategies in snowmaking, made possible by improvements to the technology, is to make snow in short, high-volume spurts that coincide with cold snaps.  For quality snow production, the rule of thumb is the colder the better.  Thus, for snowmakers, a day at 15° is a lot more hectic than a day at 25°, and when the temperature hits 32°, running the guns is like feeding twenties through a paper shredder at a rate of one per second.  As Clancy puts it, “Ain’t two days that are the same.”
