According to AccuWeather.com Meteorologist Andy Mussoline, the primary catalyst for the tornadic thunderstorms was a cold front that was moved through the region yesterday evening. Clashing with the region's hot and humid air, thunderstorms erupted.
Mussoline also noted that the storms moved northwest to southeast, an irregular pattern.
"Typically tornadoes move southwest to northeast (or move northward). The reason for the unusual movement is the cold front that pushed the tornadic storms southward," he said.
Tornadoes were reported outside of Des Moines, Waterloo and farther north near Webster City.
