A strong winter storm brought moderate to heavy snow to portions of eastern Iowa and northwest Illinois late Friday night and early Saturday morning.

Precipitation began as rain that quickly changed over to snow early Saturday.  Heavy wet snow fell east of a line from Fairfield to Iowa City, to Dubuque and generally north of a line from Burlington Iowa to Galesburg Illinois.  The heaviest snowfall amounts between 8 and 12 inches fell from extreme eastern Iowa in Cedar, Scott, and Clinton counties, to Carroll, Jo Daviess, and Stephenson counties in Illinois.  This heavy snow caused numerous accidents and downed several tree branches due to the weight of the snow.
