This is a sequence of images I took from a point 7 miles west of Jacobson, MN while spotting for the Grand Rapids area Skywarn net. This severe-warned storm became tornado-warned about the same time I took the last of these images. I chased the storm to Swan River, but it lost its supercell characteristics once I drove northeast from Jacobson.
Looking southwest at featureless skies-- maybe the hint of a storm tower.
A storm becomes visible.
A wall cloud becomes evident.
Somewhat of a collar is visible above as cloud-to-ground lightning becomes more frequent in my vicinity.
Another shot. Wall cloud below and collar cloud above.
My final shot looking out the window.
