The Sperry Piltz Ice Accretion Index leverages wind and ice accretion to measure impacts. I'm going to cut the forecasted amount in half, which would mean an Ice Damage Index of at least a 1. However, a year or two ago we had this ice event in upper Montgomery County where we got between 0.3" and 0.5" ice with almost no wind and it was impressive. A lot of trees snapping in two, event the hardwoods, which caused big problems to the power grid. Some places were out for 3 days and that was for the Allegheny Power service area which does a good job at tree trimming. Something like what's being advertised there would be probably a 2 or 3.
