Winter Storm Reminders:

		Upper Air Temps
		Borderline	Very Cold
Surface Temps	Borderline	Rain, maybe light icing	Snow, light accumulation
Surface Temps	Very Cold	Significant icing potential	All snow, higher accumulation

Only one of those four scenarios results in significant snow accumulation.

There is an average of one 4"+ snow event per year, but there tend to be several in the same winter then a few winters without one.

Cold Air Masses - General Guidelines:

Stronger and slower arriving on the front end

Weaker and faster eroding on the back end
