Ranked from NOAA 1991-2020 Climate Normals
Snowiest Counties in Illinois
Average annual snowfall by county, deepest first. Snow is the cost nobody budgets for: removal, roof load, the shorter life of a driveway that freezes and thaws all winter, and the heating demand in the column beside it. Figures are NOAA 1991-2020 Climate Normals from the weather station nearest each county seat, so they describe a thirty-year average rather than any single year. Counties with no measurable snowfall in the normals are left out rather than listed as zero.

Every figure is modelled on the county's own median home with 20% down at 7.03%. Property tax and electricity are county and state specific; homeowners insurance uses the NAIC average premium for that state, which ranges from 0.16% of home value in Hawaii to 1.16% in Oklahoma. Maintenance and water are national estimates. Full methodology.
