The two ingredients required to produce snow are moisture and cold. Snow doesn’t form unless the atmospheric temperature is at or below freezing. If the ground temperature is warmer than freezing, the snow will melt as it falls. If ground temp is low enough, the snow will stick. So while it can obviously be too warm to snow, it never really gets too cold to snow. Snow can occur at extremely low temperatures, but typically doesn’t, because super-cold air tends to be dry. Temperature also effects the type of snow. Snow that falls when temps are close to freezing typically holds more moisture, making it heavier and wetter. As temperatures drop, moisture level usually does too, making the snow lighter and fluffier. While it never gets too cold to snow, snow does become a lot less likely as temperatures drop to 0°F or below. Here’s what our friends at the National Snow and Ice Data Center have to say about it: https://nsidc.org/learn/parts-cryosphere/snow/science-snow
