This Day in Southeast Michigan Weather History ...
On September 25, 2007, thunderstorms ended a dry eight day stretch of well above average temperatures in the upper 70s to upper 80s. Some of the storms were severe with the most damage occurring in Flushing. A downburst produced estimated 80 mph wind gust which blew in garage doors and down hundreds of trees and large limbs.
Also on September 25, 1941, the remnants of a former Category 3 hurricane passed over Detroit.
What was remarkable about the remnants of this storm was the high wind speeds and low pressure that accompanied it. Winds speeds remained steady at 56mph with wind gusts of up to 75mph! Dozens of people were injured from these winds. The pressure dropped to 990mb that day, which is the second lowest pressure reading ever recorded for Detroit during the month of September.
