Cold/Wind Chill in Lake, South Dakota

Wind chill temperatures ranged from 25 to 34 below zero during the early morning hours. The AWOS at the Madison Municipal Airport briefly dipped as low as 36 below zero.

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. An arctic air mass followed the snowfall, resulting in many locations reporting wind chill values of 25 below or colder the morning of February 11.
