 Winter Storm Overview 

A winter storm brought light to moderate snow to much of eastern Iowa and northwest Illinois on March 9th, 2023.

Precipitation began as a mix of rain and snow as it overspread the region during the morning hours. Snow was observed mainly north of Highway 34 to start, with more of a rain, snow and sleet mix to the south. As the day progressed, precipitation began to change to all snow as temperatures dropped. This snow continued for most well into the early evening before tapering off by midnight.

Snow totals were highest along and north of Interstate 80 with a range of around 4 - 6 inches. Pockets of higher amounts were observed in northwest Illinois in Stephenson County, with the highest total so far measured just west of Freeport at 6.5 inches.
