Detroit Lakes or Devils Lake?
I'm guessing it was up on that overpass in the westbound lane, Seems to me I remember a wind meter up there. I saw air under semi trailer tires up there one day but it didn't tip over. That's one windy little knoll.
Hot and humid air will stream into the Northern Plains as a warm front surges north, sending temperatures rising well into the 90s. Riding over the top of that hot and humid air is much drier air and an active jet stream.
This volatile combination of ingredients ignited a bowing line of severe thunderstorms in northern North Dakota, Friday afternoon.
Those storms produced at least one wind gust over 100 mph late Friday afternoon. The 101 mph wind gust was measured along Highway 2 near Church's Ferry, North Dakota.

Update : Correction : That overpass is east of DL come to think of it.
