I watch the local weather and expect the opposite of whatever they say. If they are predicting a lot of snow (4-6" tonight, which isn't exactly a lot for northwestern PA, but...) then I expect to have a dusting. When they predict 1-2, it seems that is when we get 6+.

Last week they predicted 1-2". I cleaned 6 inches off the cars, went back out a few hours later, cleaned another 4 inches off and ran the snow blower, and in the morning cleared off another 3 inches from the car to go to work.
