The featured chart presents an IEM computed analysis of the surface low minimum pressure from Monday afternoon thru Tuesday. The low pressure center developed in Kansas and then rapidly intensified as it moved to the north and east into Minnesota. The values shown set various records for all time lowest pressure and may go down as the most powerful continental storm system in US History (as measured by pressure). The rapid intensification met the 'bombogenesis' criteria, which is an informal term that describes 'explosive' storm development by having its surface low center's pressure drop by 24+ mb in 24 hours. The primary impact of this storm on Iowa continues to be the strong winds which will continue today. Many parts of Eastern US felt this storms impact in the form of severe winds and tornados.
