3 Day (72 Hour) Snow/Sleet Amount Potential
Official NWS Forecast Snowfall Totals
The "Point" map is the official NWS snowfall forecast in inches during the time period shown on the graphic. This snowfall amount is determined by NWS forecasters to be the most likely outcome based on evaluation of data from computer models, satellite, radar, and other observations. Note that forecast snow amounts also includes sleet.

The "Range" map is the 25th percentile (lower number) to 75th percentile (higher number) of possible snowfall amounts based on the National Blend of Models (NBM) output during the time period of the graphic. The official NWS snowfall forecast influences this range of values either up or down depending upon how closely they match.

3 Day (72 Hour) Ice Accumulation Potential
Official NWS Forecast Ice Accumulation Totals
The "Point" map is the official NWS ice accumulation forecast in inches during the time period shown on the graphic. This ice accumulation amount is determined by NWS forecasters to be the most likely outcome based on evaluation of data from computer models, satellite, radar, and other observations.

The "Range" map is the 25th percentile (lower number) to 75th percentile (higher number) of possible ice accumulation amounts based on the Weather Prediction Center (WPC) Super Ensemble output during the time period of the graphic. The official NWS ice accumulation forecast influences this range of values either up or down depending upon how closely they match.
