Illinois – A prolonged winter storm brought widespread heavy snowfall across Illinois from January 23 through January 26, with top totals reaching 14 inches, according to compiled storm reports.
The highest snowfall total reported in the state was 14.0 inches in Johnston City, making it the snowiest observed location in Illinois during the multi-day event. Several additional communities across southern Illinois recorded snowfall totals near or above 13 inches, highlighting the storm’s concentrated impact across the region.
Among other high-end reports, Olney (1 mile southeast) measured 13.8 inches, while Oblong recorded 13.4 inches. Elkville (1 mile south) reported 13.3 inches, and multiple locations—including Albion, Benton, Fairfield, McLeansboro, and Tamaroa—each recorded 13.0 inches.
Additional snowfall totals include 12.6 inches near Mount Vernon (4 miles north), rounding out a broad area of double-digit accumulations across southern and southeastern Illinois. Snowfall totals generally decreased farther north across the state, reflecting the storm’s sharp north-to-south gradient.
Snow accumulated steadily over multiple days rather than falling in a single intense burst, extending travel disruptions and placing prolonged demand on road crews. Major corridors including Interstates 57, 64, and 70 experienced periods of slick roads, reduced visibility, and slowed traffic, particularly during overnight and early morning hours.
Cleanup operations continued after snowfall ended as cold temperatures limited melting, allowing snowpack to persist on secondary roads, bridges, and shaded areas. Narrowed roadways and lingering slick spots remained concerns even after precipitation tapered.
The January 23–26 storm ranks among the most significant snow events of the season for Illinois, especially across southern portions of the state, contributing meaningfully to seasonal snowfall totals.
