Episode Narrative A very intense storm system tracked from the Oklahoma Panhandle to western Illinois and then to Lake Huron. This had the lowest barometric pressure (975 mb or 28.79 inches) in the Midwest since the November 10, 1998 storm that also moved through the upper Midwest. This powerful winter storm produced very heavy snowfall, blizzard conditions and bitterly cold temperatures on December 8-9, 2009. Snow amounts of at least 10 to 15 inches were common north of a Fairfield, Iowa to Sterling, Illinois line. The largest amount was an incredible 17.7 inches at Orangeville, Illinois in Stephenson county. Other amounts included 15 inches at Brighton, Iowa (Washington county), Mt. Vernon, Iowa (Linn county) and at Freeport, Illinois (Stephenson county). Snowfall was much lighter in southeast Iowa, extreme northeast Missouri and west central Illinois. Here snow accumulations were 1 to 4 inches as rain and sleet mixed with the snow. A band of freezing rain from Burlington, Iowa to Sterling, Illinois coated trees and power lines with up to 3 tenths of an inch of ice. A few locations also reported thundersnows with snowfall rates of nearly 2 inches per hour. There were scattered power outages and some tree branches down. Numerous accidents and vehicles sliding into ditches were reported across the region. Many schools and businesses were also closed. In addition, winds gusting over 50 mph produced widespread blizzard conditions across much of eastern Iowa and extreme northeast Missouri, reducing visibilities to near zero on December 9.
Event Narrative A COOP observer 3 miles north of Stockton reported a total of 13.0 inches of snow for this event.
