The Snowiest County in Every State

Print Email

According to a recent analysis by AccuWeather, the return of an El Niño weather pattern will bring cold temperatures and above average snowfall to much of the mid-Atlantic region this winter season. While, on average, much of the southern half of the United States receives just a few inches of snow each year, most states have at least one county where snow falls both frequently and in relatively large quantities.

Snow forms when the atmospheric temperature is at or below 32 degrees Fahrenheit, and when there is a minimum amount of water vapor in the air. While colder places tend to have more favorable conditions for snow, the coldest counties in a state are not necessarily the ones that receive the most snowfall in a given year.

To the identify the snowiest county in every state, 24/7 Wall St. calculated the average snowfall on days when it snowed during the winter months — December, January, and February — from 2016 to 2018 for all U.S. counties using weather station-level data from the National Oceanic and Atmospheric Association.
