One of the most significant thunderstorms to hit Metro Detroit appeared on radar as a monster’s claw, scraping southeastern Michigan as it headed north toward the thumb region.

Once Monday’s rainfall stopped, Detroit Metro Airport in Romulus set a near record with 4.57 inches of rain, second only to the 4.74 inches, which fell on July 31, 1925. In all, 4-6 inches of rain fell in a four-hour period, impacting Metro Detroit, Flint and the Saginaw Valley.

“This event was caused by a low-pressure system moving over the area, and with the atmosphere being very moist, created the heavy, continuous rains that were seen,” according to the weather service.

Canton Township reported more than 4 inches of rain by 6 p.m. Monday — including 3.45 inches in three hours, the National Weather Service said. Parts of Livonia also saw about 2 inches in two hours.

Other rainfall totals included 5.2 inches in Warren; 4.9 inches in Rochester; 4.54 inches in Southfield; 4.25 inches in Taylor; 4.16 inches in Garden City; 4 inches in Livonia; 3.75 inches in Dearborn; 3.10 inches in Romeo; 2.6 inches in Farmington; and 2.25 inches in Berkley, the weather service reported.
