As a major heat wave blazes much of the central United States through the Labor Day weekend, rounds of storms will rim the heat from the Great Lakes to the Northeast and neighboring Canada.
While most of the storms will not be severe with sporadic rainfall and a mere breeze, a small number of storms can be nasty with damaging wind gusts, hail and frequent lightning strikes.
Even if the storms do not turn severe, torrential rainfall can affect a small number of locations. Flash and urban flooding can occur where downpours repeat.
Poplar, Wis., received 6 inches of rain as of Tuesday morning, and flooding forced roadways to close in Okemos, Mich. At Williamsburg, Mich., during Tuesday afternoon, 1.16 inches of rain fell in an hour. Later, Tuesday evening, Cadillac, Mich., experienced flash flooding which covered roads downtown in water, and 3.1 inches of rain fell in 3 hours near Marion, Mich.
A few communities can be hit hard by the storms with power outages. The showers and storms were not limited to the afternoon and evening hours, as plenty of heavy rain fell across southern Michigan into the morning hours on Wednesday.
People should be prepared for sporadic travel delays at the airports and on the highways.
Cities that can experience storms on more than one occasion this week include: Green Bay, Wis.; Detroit; London and Toronto, Ontario; Buffalo and Albany, N.Y.; Burlington, Vt.; Portland, Maine; Hartford, Conn.; Pittsburgh, Scranton and Harrisburg, Pa.; and Baltimore.
