Muggy, hot weather staying put with 'persistent system'

After torrential rains drenched parts of the suburbs, forecasters are calling for a dry, but muggy end to the weekend.

One of the highest rainfall totals was reported in Des Plaines, where 1.2 inches fell in just 10 minutes Saturday afternoon, according to the National Weather Service.

In Arlington Heights, rains caused flooding near the railroad crossing at Northwest Highway and Euclid Avenue, police said.

The soggy afternoon caps three straight days with rain in DuPage County, where stormwater management crews began operating facilities designed to curb flooding, including the Fawell Dam along the West Branch of the DuPage River in Naperville. As much as 4 inches soaked parts of the county from Thursday afternoon into Friday morning, officials say.

Muggy conditions will stay put through the weekend and into early next week, forecasters say.

"It's not going to be nice unless you like it hot and humid," said Charles Mott, a meteorologist with the weather service's Romeoville branch.

Temperatures should climb into the upper 80s to low 90s Sunday. Heat indexes, though, could reach as high as 102, according to the weather service.

"We have a system that is being persistent," Mott said. "It's not moving much at all."
