How much snow the county got each winter since 1888, and how one corner differs from another. The county line averages the stations that were actually measuring that season. Pick a station under Compare a station and the gap is not small: measured against the county over the same seasons, Devault runs about 9½ inches a season above it and East Nantmeal close behind, while Phoenixville and the southern lowlands run 6 to 8 inches below. That is the county’s north-to-south elevation gradient, in snow.

Measure also gives first and last measurable snow of each season and the season’s biggest single day; below the chart, How one season piled up replays any winter day by day.

For the ranking of biggest and smallest winters see Top Snowfalls by Season; for individual storms, Top Snowfalls by Month; and for Christmas, White Christmas History.
