About this data
Station: NOAA’s Clarence station (GHCN USC00361480), elevation 1,390 ft, 41.049° N, 77.941° W. These are NOAA’s 1991–2020 U.S. Climate Normals, 30-year averages that NOAA recomputes every 10 years. NOAA rates this station’s precipitation normals standard, its snow normals standard and its temperature and freeze normals representative. Standard means at least 24 years of data, with missing months filled from nearby stations. Representative means at least 10 years of data, with missing months filled from nearby stations.
Your yard can differ from the station. Elevation, valleys and hillsides change how much snow falls and when the first and last freezes come.
