Here’s the Lake Michigan satellite pic. from Tues. PM. It was partly to mostly sunny with a west-southwest wind. That wind direction made quite a difference…air that crossed Lake Michigan was much warmer than air that did not. On the other side of the lake, Chicago (O’Hare) had a high temp. of 7. By the time that air got to the S. Haven Beach – it had warmed up 10-15 degrees. The high at the beach at S. Haven was 19, at the Muskegon beach it was 21. It got colder the farther south you went. Grand Rapids had a high of 19, Kalamazoo had a high of 12, Sturgis had a high of 6 and South Bend, Indiana had a high of 2. Lafayette IN had a low temp. of -19 – that was 38 degrees colder than average! The average wind speed in Lafayette thru 5 pm was 5 mph – so those wind turbines were not generating a lot of electricity on a day with high demand due to the cold. And…more to come. Dr. Ryan Maue says: “extremely dangerous cold from brutal wind chills will wreck the Midwest and Northeast during day Friday into Saturday.” The GFSX model has the strong wind here next Sunday.
