Three people are dead in North Dakota, and tens of thousands are without power in northern Minnesota and northwestern Wisconsin after powerful winds swept across the upper Midwest Friday and overnight Saturday.

Tornadoes ripped through North Dakota, killing three. The storms also reached northern Minnesota, causing severe damage. FOX 9's Leon Purvis has more.

Extreme meteorologist and storm chaser Reed Timmer was at the scene of Friday’s tornado east of Jamestown. He and his crew tracked the tornado with the ‘Dominator’.
