Overview
|
A strong area of low pressure tracked east across Kansas, Missouri, and central Illinois on Sunday, bringing heavy snowfall and gusty winds to the region. This caused blizzard conditions across much of southeast Iowa, northeast Missouri, and northwest Illinois, with zero visibility at times during the afternoon and evening. Strong north winds between 30 and 50 mph were reported during the storm. The heaviest snowfall reports between 8 and 12 inches were common from a line from Sigourney, IA, to the Quad Cities, to Sterling Illinois. A sharp cutoff of little to no snow was found on north end of storm generally in a line from the Cedar Rapids airport to Dubuque.
