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.
