Cold does not stop snow. Dry air does. The colder it gets, the harder the atmosphere has to work to produce meaningful snowfall. Snow can fall at extremely low temperatures when the ingredients line up. The atmosphere only needs three basics: moisture, lift, and air cold enough for ice crystals to survive to the ground. If a storm can deliver water vapor and force air upward, snow can happen well below zero.
