Episode Narrative A strong Alberta clipper dropped out of the northern Plains spreading snow across much of the region on January 6-7, 2010. Snow began across eastern Iowa during the afternoon of the 6th, before spreading east later in the evening. Snowfall amounts of 6 to 9 inches were common across much of eastern Iowa and northwest Illinois. However, accumulations were in the 2 to 5 inch range in southeast Iowa, western Illinois and extreme northeast Missouri. The highest total reported was 9.8 inches at Bertram in Linn county in eastern Iowa.

The system was mainly forced by the upper levels, where dynamics helped to organize the snow into heavier bands. With a weak surface reflection, winds were also relatively light during the snowfall. This, coupled with temperatures well below normal, yielded snow to liquid ratios in excess of 20:1, and in some cases greater than 25:1. The result was a light, fluffy, and very picturesque snow that piled up quickly. By the morning of the 7th, a dry slot had nosed into parts of the area south of Highway 34, bringing an end to accumulating snows until later in the day. This helped to hold final totals down across southeast Iowa, northeast Missouri and extreme western Illinois. With the system pulling off to the east later on the 7th, wrap around snows brought another inch or two of accumulations to some areas before tapering to flurries.
