Lake Michigan seems to have an effect on storms in Wisconsin. I live 3 miles west of Lake Michigan. When the lake is cool (water temps 40s and 50s) in the spring, storms do weaken and/or die when they approach the lake. Later in summer though, (July, August, early September), when the lake temperature reaches the low to mid 70s, storms don't weaken. It always ruins my parade to see a strong supercell move at me all the way across Wisconsin, and then die right as it enters my county. Granted, when I have the opportunity, I do drive west to intercept any decent storms before they have the chance to die.
Oh....I relate to the "ruin the parade" syndrome! It happens so much here too!
