Randy Chabot is a refrigeration contractor, recently transplanted from Michigan to Ellicott City. He wrote last year, amazed and wilted by our Chesapeake summers. Now he's fretting about summer 2007: "My interest ... is not just about comfort, but financial also." The feds' Climate Prediction Center says we're in for a warmer-than-normal summer, with equal chances for above- or below-normal rainfall. Hurricane forecasters warn of a busier 2007 season, with several East Coast landfalls. You'll be busy.
