Snowstorms can be on different scales. You can have Alberta clippers, Panhandle hooks, or Nor'Easters that affect entire regions. In addition, you can have lake effect snow squalls that affect a mesoscale area of only a few square miles. Larger scale snowstorms usually involve low pressure centers and moisture from an ocean. Lake Effect requires moist, unsettled, cold air flowing over relatively warm lake/sea water.
