Heavy rains drenched Omaha on Tuesday, leaving high water on roads just in time for rush hour. To make matters worse, the city's 911 call system went down, according to Omaha.com. There was no immediate word what caused the outage.

Tuesday afternoon, firefighters in Omaha had to rescue a woman and two infants from a car that was swamped by floodwaters in an underpass, according to WOWT.com.

"In a situation like that, low-lying areas are going to flood – especially when you have rain that's hitting your car so loud that you can't even hear yourself think," said Jim Cantore, storm tracker for The Weather Channel.

One Weather Underground Personal Weather Station in midtown Omaha recorded 0.96 inch of rain in a 10-minute span between 3:31 and 3:41 p.m. local time Tuesday afternoon – a rate of nearly six inches per hour.

Later Tuesday night, another water rescue had to be performed when a woman's car became stuck in floodwaters along 72nd Street. According to the Omaha Fire Department, the woman was successfully rescued from her vehicle.

Portions of Interstate 80 in Omaha were partially flooded Tuesday night, according to local reports. As of late Tuesday night, there were no reports of injuries or deaths from the storms.

In northwestern Missouri, tree and power line damage was reported in Fairfax by storm chaser Kelly Lange. To the east, flooding caused vehicles to be stranded in North St. Louis as heavy rain moved through the area.

Law enforcement reported a tornado on the ground shortly after 7 p.m. near Maitland, Missouri, a Holt County town of about 340 people. There were no reports of damage, but trees and power lines were down.

In Atchison County, Missouri, the city of Tarkio lost power just before 6 p.m. as winds with sustained speeds of 70 mph blew through.

Reports of more than six inches of rainfall Tuesday afternoon and evening were relayed from Union County, Iowa, and more rain was expected to fall.

Golf ball-sized hail was reported south of Omaha in Otoe County, Nebraska, and large hail was also reported by storm chasers in southwestern Iowa Tuesday evening.

The severe threat is expected to push into the eastern Great Lakes by Wednesday, and then possibly bring heavy rain and high winds to the Northeast on Thursday.
