...NWS damage survey for 07/21/14 tornado event in Polk and Red Lake County MN...

A large scale Bow-echo type squall line moved across northeast North Dakota and northwest Minnesota during the evening of 21 July 2014. A tornado formed on the apex of this squall line and moved from southwest Polk County Minnesota into southwest Red Lake County. The tornado itself was likely wrapped in heavy rain and more widespread damaging downburst winds. The tornado track itself was distinguishable by the presence of more extreme damage and an apparent lofting and throwing of debris. In addition...several rural residents noted the apparent roar of the storm along with its brief and catastrophic impacts.
