Probabilistic Snowfall Products

Probabilistic snowfall products are intended to provide a range of snowfall possibilities. These products complement the existing NWS forecast in order to better communicate forecast uncertainty and enhance Impact-based Decision Support Services (IDSS) before and during winter weather events.

Probabilistic snowfall products are currently available across the contiguous United States, including 116 of the 122 local NWS Weather Forecast Offices. These experimental forecast products help to explain the range of snowfall possibilities for upcoming winter storms (most likely snowfall, maximum and minimum snowfall), helping everyone make better decisions on what action to take.

Knowing the forecast and adequately preparing for a storm can lessen the impacts associated with hazardous winter weather. For more information on how to interpret these products, please see the fact sheet and video below.
