BPI (Blizzard Probability Index): This proprietary index calculates if the chosen model forecasts that the minimum thresholds for a blizzard have been reached. If an area is in the green, the model forecasts that the minimum threshold for a blizzard have been reached, grey means that the conditions are close. Historically, the NWS does not issue a blizzard warning until yellows or above have been reached. This index does not cover ground blizzards, I am working on a version that will cover that scenario.
