Climatologist Brian Brettschneider compiled snowfall data from around the United States and Canada, creating a map to show which month is the snowiest for each location with an average annual ...
Weather stations with highest snowfall in the United States by state, 1985-2015; State Place Average annual snowfall [3] elevation of weather station [4] coordinates [4] Other snowy areas (limited or unofficial data) and notes 1. Washington: Paradise, Mount Rainier: 645.5 inches (1,640 cm) 5,400 feet (1,600 m)
The annual average temperature is relatively high in the southwestern part of the country (5.0 to 7.5 °C or 41.0 to 45.5 °F), with quite mild winters and warm summers, and low in the northeastern part of Lapland (Finland) (0 to −4 °C or 32 to 25 °F).
The lake effect largely contributes to the 55–80 inches (140–203 cm) annual snowfall amounts recorded south and east of the lake, and an average snowfall reaching 500 inches (13 m) in the Wasatch Range. The snow, which is often very light and dry because of the semiarid climate, is referred to as the "Greatest Snow on Earth" in the mountains.
There has already been a 2.7% decline in annual global snowfall since 1973, according to Brettschneider’s analysis of data from the European Union’s Copernicus Climate Change Service.
These snowfall maps are simply fun to study—and compare to what happens by the end of the season. In a normal winter (January through March), the jet stream pushes south, nudging storms down, too.
The regional snowfall index (RSI) is a system used by NOAA to assess the societal impact of winter storms in the United States. The system is a replacement for the Northeast snowfall impact scale (NESIS) system. Since its initiation, the NCDC has retroactively assigned RSI values to over 500 historical storms since 1900.
