A mid-level disturbance from Canada moved southeast across the Dakotas into Minnesota February 10-11, resulting in periods of light to moderate snowfall. The highest snow totals, exceeding 6 inches in some places, fell along a narrow west to east band just south of Interstate 90 across southeast South Dakota, coincident with the strongest low level frontogenesis.
