May 2001 1st-3rd. Showers, chiefly for Great Lakes. Pleasant weather, but unsettled conditions to the south could possibly make for thundery conditions on Derby Day in Louisville. Squally conditions spread into the Ohio River Valley from the West. Fair for Michigan, Illinois and Wisconsin.
Sunshine gives way to increasingly cloudy skies.
