Southwest Lower Michigan Weather History

The Weather History for July 31st

Very heavy rains during June and July cause the Grand River to rise to unusually high summer levels. Lumber companies use the high water to float logs to a log boom upstream of Grand Rapids. The logs broke loose and crashed into the Detroit, Grand Haven & Milwaukee Railroad bridge creating a jam estimated at thirty-feet deep and seven-miles long. Sections of Grand Rapids were flooded by backwater. Eventually the bridge gave way and several bridges downstream were damaged by the cascading logs.
A heat wave produced record highs in the upper 90s as July ended, with Grand Rapids hitting 98 degrees and Lansing 96 degrees. There were also record high minimum temperatures of 79 degrees at Grand Rapids and 74 at Lansing.
Hot and dry weather during the month leads to drought conditions along the Lake Michigan coast. Agricultural production was hampered as the dry conditions continue into August. is the U.S. government's official web portal to all federal, state and local government web resources and services.
