A heat wave began on the 30th and persisted until August 1 (see August Storm Data for information regarding August 1).  Temperatures on July 30 soared into the upper 80s and lower 90s across a large portion of central and southern Minnesota, while dewpoints climbed into the middle 70s to lower 80s, resulting in triple digit heat indexes during the afternoon and evening.  Some noteworthy index values include 113 at Redwood Falls (Redwood County), 111 at Morris (Stevens County) and Mankato (Blue Earth County), 110 at New Ulm (Brown County), Fairmont (Martin County) and Maple Lake (Wright County), 108 at Cambridge (Isanti County) and Lakeville (Dakota County), and 107 at Little Falls (Morrison County).During the early morning hours of the 31st, dewpoints remained in the 70s, therefore nighttime heat indexes only dropped to the upper 70s and lower 80s.   In fact, from 1000 CST July 30 to 1600 CST July 31 inclusive, Minneapolis-St. Paul (MSP) set a record with 31 consecutive hours during which the dewpoint was equal to or greater than 74 (the previous record was 25 hours in July 1977).On July 31, temperatures climbed slightly higher, while dewpoints remained in the middle 70s to lower 80s.  Heat index values reached triple digits prior to Noon in most areas.  Some noteworthy values include 122 at Staples (Todd County), 115 at Little Falls (Morrison County), 114 at Morris (Stevens County) and Rush City (Chisago County), and 112 at Mankato (Blue Earth County).  The heat wave expanded eastward into Wisconsin on the 31st (see corresponding entry for West Central Wisconsin), and continued into August 1 over both Minnesota and Wisconsin (see August Storm Data).Korey Stringer, a professional football player for the Minnesota Vikings of the NFL, practiced during the late morning of the 31st in Mankato (Blue Earth County).  He collapsed shortly after practice and was taken to the hospital.  Mr. Stringer died on August 1 and his fatality will be listed in the August Storm Data.
