A strong arctic front out of the northern plains pushed south across the midwest resulting in rapidly dropping temperatures. In some cases, sites saw temperature drops of 15 to 20 degrees over the course of an hour or so and very strong northwesterly winds ushered in arctic air. The rapid drop in temperatures also induced a flash freeze scenario for much of the state where liquid on area roadways from light rain and melting earlier in the day quickly froze and the front swept through.
