Winter Archive

The method by which individual accuracy scores are calculated is as follows:

  • An average forecast amount is calculated by averaging the forecast range. For example, a forecast of 1-3″ has an average forecast amount of 2″.
  • The actual snowfall amount is subtracted from the forecast amount to determine forecast error.
  • The forecast error is subtracted from 10 to determine the accuracy score.
    • Accuracy score cannot be lower than 9.0 if the actual snowfall was within the forecast range.
    • An outlet forecasting 0″ is automatically assigned a minimum score of 5 when actual snowfall is 1″ or more.

Note: Accuracy Scores marked in red denote manual override of calculated score based on the criteria stated above.
