Summary

An area of moderate to heavy snow moved northeastward across northern Illinois and far northwest Indiana during the late afternoon and early evening of Tuesday, Dec. 29.

Snowfall rates of 1 inch to locally 2 inches per hour were observed in this band of snow.

By mid-evening, warming temperatures aloft resulted in the precipitation mixing with sleet and rain before changing over to all rain for much of north-central and northeast Illinois by late in the evening.

Air temperatures remained below freezing for several hours after the switch to rain, resulting in ice accumulations of 0.1 to 0.2 inches for much of northeast Illinois late Tuesday evening into early Wednesday morning.

This was the first significant winter precipitation event this season for most of the NWS Chicago forecast area with the exception of locations near the Wisconsin state line. The high snowfall rates during the late afternoon and evening resulted in major travel disruptions across northern Illinois and the Chicago metro.
