Weathermen Suck

How can you possibly be wrong 80% of the time and still have a job? I just don't get it. I have a forecast for no snow tuesday, yet I wake up to 4" on my car that need to be cleared off before going to work! Not that I mind the excuse to be late, but I need to be mentally prepared to wake up to a winter wonderland! Time is flying I can't wait til vacation!
