8-10-12  --  A well-known weather expert predicts August will be generally cooler and more rainy than our record hot July.  And U-of-M Climatologist Mark Seeley says other records were broken last month:  Saskatchewan had more tornadoes in July than the entire U-S 50 states -- the first time that's ever happened.  Seeley points to a changing climate across the U-S and other northern land masses.  He expects extreme weather to break more records in the coming months and years.
