Folks in Minnesota are experiencing some chilling weather this Halloween, with snow accumulation showing up on Minnesota Department of Transportation cameras in New Ulm. But how common is a white Halloween?

The WeatherRadar is showing snow falling in New Ulm and Minneapolis. It looks like it will be a white Halloween for parts of Minnesota. However, across much of the Lower 48, the chances of seeing a white Halloween are quite slim.

In the Lower 48, the highest odds of a white Halloween are in the highest elevations of the northern and central Rockies. Spots west of Denver, near Yellowstone National Park and northwestern Wyoming, have a 25% to 50% chance of having at least an inch of snow on the ground on Halloween.

The rest of the Rockies have around a 10% to 25% chance of a white Halloween. Parts of the Cascades, northern Plains, northern Minnesota and Michigan's Upper Peninsula have a 10% to 25% odds of a white Halloween.

The rest of the lower 48 has slim chances of a white Halloween, typically 10% or less, with much of the South being virtually snow-free on Halloween over the last 40 years. If you want to know whether a white Halloween is in your forecast, check out the WeatherRadar.
