Topic driven playlist

Thunderstorms capable of producing flash flooding and locally damaging winds will shift across the midwestern United States into Wednesday night.

Thunderstorms are expected to ramp up in intensity and coverage from western Michigan to Kansas late on Wednesday afternoon into Wednesday night.

"By late on Wednesday, storms will unfold from the Kansas City, Missouri, area to Moline, Illinois and Milwaukee, Wisconsin," AccuWeather Meteorologist Michael Doll said.

The heaviest storms may hold off in Chicago until Wednesday night.

"The most powerful storms into Wednesday night can cause high winds that can bring down trees and power lines and perhaps cause some minor damage to structures," Doll added. "Hail is likely as well."

Ample amounts of heat and humidity ahead of a front will help fuel stormy weather into Wednesday night.

The storms have the potential to produce significant rainfall in a short amount of time.

Flash flooding could be a problem as the storms will dump torrential downpours over ground that is already saturated, according to Doll.

Motorists should be on alert for drastically reduced visibilities and standing water on area roadways.

Beyond Wednesday night, spotty, but locally heavy and gusty storms will advance into the Northeast on Thursday.

Across the central Plains, storms with flooding downpours are expected to linger into Thursday as moisture from Newton is pulled into the region.
