Sam Cohen of Baltimore noticed last winter when "lake-effect" snows buried Buffalo, N.Y. Cold air blowing across warm Great Lakes water kicks up huge snowfalls on the lee shores. He asks, "Did they ever get huge amounts of rain in the spring or summer?" In summer, they see the reverse - warm air over relatively cool water. That's so stable that areas downwind of the lakes in summer are some of the sunniest in the region. But the first cold blasts of autumn can trigger heavy lee-shore rains.
