A large and slow moving intense low pressure system tracked out of the southern Plains and into southern Illinois and then to Lake Erie on February 26-27, 2013. In the meantime, an upper level low pushed across western Illinois and into the western Great Lakes region. This cyclone spread moderate to heavy snow across much of the area with snowfall amounts of 5 to 10 inches common, with isolated higher amounts. Wind gusts were in the 30 to 35 mph range producing some blowing and drifting as temperatures hovered near the freezing mark. At the height of the storm, snowfall rates of 1 to 2 inches per hour were reported. The highest amount of snow was 11.8 inches northeast of Downing, Missouri in Scotland county. An observer near Stanley, Iowa in Buchanan county measured 10 inches with almost 9 inches near Farmington in Van Buren county. At Freeport, Illinois in Stephenson county nearly 8 inches was reported. Due to the heavy wet nature of the snow, combined with strong winds and temperatures near freezing, some power outages were noted.
