Where these numbers come from
Climate: NOAA NCEI U.S. Climate Normals 1991–2020 (annual, monthly and daily station normals) for Pittsburgh International Airport, GHCN-Daily station USW00094823, 19 km from the city centre. First and last snow dates, the share of winters with snow and the snowiest winter were counted by this site from the same station's daily snowfall for the winters 1991–92 to 2020–21, read through the Regional Climate Centers' ACIS service; a winter with more than 10 missing days between October and April is left out. Forecast: the National Weather Service API, read at most once an hour. All US government data, public domain.
