A potent low pressure system tracked from eastern Oklahoma and Missouri into northern Illinois and the Great Lakes region, from December 28th to the early morning hours of the 29th. An unseasonably warm and moist airmass interacted with the system to produce heavy mixed precipitation across the region. Thundersnow was reported in some areas, as well as heavy snow, sleet accumulations up to 2-4 inches, and glaze ice amounts over a quarter inch. The ice and strong winds gusting to 50 mph resulted in widespread downed trees and powerlines, and power outages. The hardest hit areas, with glaze ice amounts of 1/4-1/2 inch, were located from southeast Iowa, across the Mississippi River into Henderson, Mercer, Warren, Rock Island and Henry counties in Illinois. The highest amounts of combined snow and sleet, in the 5-7 inch range, occurred west and north of a line from Brighton, IA in Washington County, to Cedar Rapids, Anamosa, and Stockton, IL. |
