Some great videos this week's Polar Vortex like; a rescue from a frozen Lake Michigan, flyover of a frozen Lake Michigan and more. This week we have been through the ringer when it comes to weather; we had snow on Monday and some Tuesday, then we had -30 windchills and now this weekend its going to be 40 degrees. And there were some great videos this week showing just how insane the cold was such as first up, a video from WGN News and the Chicago Police which rescued a man from Lake Michigan after he went to rescue his dog.

If that one was a little too crazy this will calm you down and might make you cold again as they are both showing just how frozen Lake Michigan was this week. One shows a flyover of Lake Michigan and another shows the ice balls that washed up on the beach.

This last one is from MLive which shows how frozen everything was at St Joseph North and South Piers in St. Joseph, Michigan.
