Since most storms move west to east, I'll give you a heads up on when to expect to get wet - or - you can just take my regular commute time (I'm an 8 to 5'er) and add the time it takes a storm to get from Michigan to Toronto and bingo (or Wham as you so eloquently said it) you are wet.

Today, it rained on the way to work, cleared up for a beautiful day and rained again just after 5:00, the first round should be at your place about 10:00 tonight!
