A clash warm and humid inland air and cold air over Lake Superior clashed this afternoon as the wind kicked up off the lake, blowing a heavy blanket of fog in over Duluth. Inland temperatures soared into the upper 70s and lower 80s, while it was closer to 50 degrees next to the shoreline. The clash of warm and cold gave us this cool video, which took place over the course of about 10 minutes around 5:30 this afternoon. The second video below shows the scene of the early reaches of fog enveloping parts of Duluth and Superior.
