A strong upper-level disturbance shifted through the Great Lakes region in the afternoon of Friday January 7th. Cold air flowing over the relatively warm waters of Lake Michigan generated several rounds of heavy lake effect snow bands beginning on Friday the 7th and ending by the morning of Sunday the 9th. The bands generated snowfall rates of up to 4″ an hour with visibilities dropping to near zero under the heaviest bands. Areas in Berrien County, Michigan and La Porte and St. Joseph counties in Indiana were especially hard hit with many locations receiving 2 to 3 feet of snow by the time the event ended.
