This index, from NOAA's National Weather Service, attempts to scale the impacts from winter weather, taking into account factors such as snowfall, accumulated snow on rooftops, ice accumulation, the potential for a flash freeze, and blowing snow. Not all factors are in play in a given winter storm.

The major storm is set to hit starting on Jan. 23 and will stretch into the weekend, spreading snow and ice from the southern Plains to the Northeast.
