Are we really that unpredictable?

Growing up in Michigan my whole life I've heard many people say that our weather is unpredictable. We had 94.9 inches of snow last winter and today we barely have an inch outside. It was 30 degrees two days ago and now it's below 0. We definitely have a case to make for unpredictable weather. A chart brought the question to my attention as if we ranked Detroit against other cities for unpredictable weather we don't rank very high. Th ranked cities were Kansas City, Missouri , Oklahoma City,Oklahoma and Minneapolis, Minneosta. They used different things such as precipitation charts and severe weather charts. The most predictable weather is in places like Las Vegas or LA. I guess Detroit is pretty average after all
