Overview
A weak surface Low tracking along the international border with an attendant warm front sparked off severe storms near the warm front and in the warm sector. The day started with a few severe storms, but 50 knot bulk shear, and MUCAPE near 1500 J/kg contributed to storms with supercellular characteristics in northwestern Minnesota in the afternoon and evening hours of June 12th.Tornadoes:
In addition to the tornado below, there was another tornado that tracked through an open field. No damage was reported, so no survey was conducted.
Tornado - Spruce Valley

Pic of the wicked #supercell moving through the swamps west of Red Lake, MN this afternoon. The structure and colors were awesome as it moved into the swamps and a funnel even poked out of the bottom for a bit in this pic. #mnwx #nikon #StormHour #ThePhotoHour pic.twitter.com/vQN1sVM5sa
Some video from the gnarly supercell near Goodridge, MN this afternoon. Saw some possible #tornadoes but never anything definitive. Was spinning like a top in multiple places. Followed it into the Red Lake marshes. Full video to come eventually! #mnwx @NWSGrandForks #nikon pic.twitter.com/LtezIzKkOg
