About this data
Station: NOAA’s Tionesta 2 SE Lake station (GHCN USC00368873), about 2 miles southeast of Tionesta, elevation 1,200 ft, 41.479° N, 79.443° 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 representative, its snow normals provisional and its temperature and freeze normals representative. Representative means at least 10 years of data, with missing months filled from nearby stations. Provisional means at least 10 years of data, with gaps NOAA could not fill 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.
