SNOWFALL REPORTS FROM THE JANUARY 6/7TH SNOWSTORM

Jan 8, 11:46 PM

Jan 6-7 Snowfall Totals

During the day on January 6th a strong Alberta clipper dropped out of the northern Plains, spreading snow over the upper Midwest. Snow began across eastern Iowa during the afternoon of the 6th, before spreading east later in the evening.

The system was mainly forced by the upper levels, where dynamics helped to organize the snow into a heavier band from northwest Iowa, to near Muscatine. 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, brining 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.
