A complex of storms coming out of the Dakotas will intensify and become a squall line with wind gusts to 70 mph. In the end if the system really gets going, it can be classified as a Derecho. Model soundings suggest winds will be gusting over 70 mph with the passage of the squall line. I expect the line of storms to go from Iowa to Kentucky before weakening. Winds of this nature can cause significant damage to trees and property.
