Western Midwest Tornado Averages

Iowa, Minnesota, Missouri

This area of the United States has a somewhat uneven distribution of tornados due to it covering considerable north/south distance. Missouri is a state that can expect a tornado just about any time of year, while Iowa and Minnesota are generally shut out in winter thanks to the cold air. The peak of the season in Missouri comes in May, while Iowa and Minnesota favor June or later in the northernmost reaches. Parts of this region, Iowa in particular, are often included in Tornado Alley.
