The storms that matter here arrive backwards. Moisture swings up from the southeast, runs into the Front Range, has nowhere left to go but up, and comes back down on Commerce City heavy and wet and all at once — the kind of snow that bends a branch and buries a parked car to the door handle. Front Range Services Incorporated reads that setup the way other people read a calendar: trucks staged, shovels in the bed, ice melt loaded, routes ordered so the earliest departures get opened first. Drives and lots cleared, walks cut down to bare ground, the shaded corners treated before they can glaze over. When a foot of upslope lands overnight, the morning still works.
