A phenomenon where bad weather surrounds a specific location, but never actually affects that location. Used when you work outdoors and can see a thunderstorm rolling in that might close down your location, but it never actually starts raining or when snow is predicted for your area, but never falls which means schools are not closed. Named for the famous Smitty of the Sports Complex who secretly had a weather machine.
Girl: Oh, shazaam, look over there! We'll be going home early for sure!
Girl2: Nah, Smitty's Dome is up...that storm will never reach us!
