A rather strong system will track from the Plains through the Great Lakes through Sunday night, spreading heavy rain and thunderstorms on its journey.
With abundant moisture for the system to feed off of, flooding downpours will be a major concern as heavy rainbands and thunderstorms form.
Many major cities will be in the zone for potential flooding, including Kansas City, Mo., Madison, Wis., and Milwaukee, Wis.
The highest risk of flooding will be in low-lying and poor drainage areas as well as locations near rivers and creeks.
Many factors are contributing to the flooding threat. Saturday was an active day from eastern Kansas to Michigan with heavy rain and thunderstorms soaking folks in this area. Many gauges collected between 1 to 2 inches of rain, leaving the ground rather saturated. Sunday will feature another heavy round of rain for this area.
Recently melted snowfall across Michigan has left the ground rather saturated there as well. Heavy rainfall is less likely to be absorbed and will instead run off and pool in low areas. Colder and harder soil will help increase the run-off threat as well.
Any leftover leaves from autumn could possibly clog storm drains, leading to flooded roadways.
This system could drench the region with 1 to 3 inches of rainfall through Sunday night. Due to the track of the system, heavy rainfall may soak the same area for a long duration.
Quick rises in rivers and streams are possible and folks living near them should have a plan of action for flash flooding.
Travel could be disrupted on Sunday due to blinding downpours and flooded roadways. Motorists are urged to turn around if they encounter high water. Slower speeds are encouraged as well to avoid hydroplaning.
The wet weather caused umpires to delay Sunday's match-up between the city's White Sox and the Cleveland Indians in the fourth inning. The 1:10 p.m. CDT start of the game was also delayed.
Drier conditions will begin to work into the region late on Monday and Tuesday.
Multiple tornadoes touched down across Indiana and Ohio on Wednesday, one of which flattened a Starbucks in the town of Kokomo, Indiana.
A budding tropical disturbance has the potential to strengthen significantly and reach Florida and the Bahamas with strong winds, coastal flooding and torrential rainfall during Sunday and Monday.
Rounds of showers and thunderstorms will bring the potential for flash flooding and localized damaging wind gusts through Thursday.
Stargazers will want to dig out their binoculars and telescopes this weekend as Venus and Jupiter shine so close that they appear as one large, bright star in the evening sky.
Following a taste of autumn chill to start the week, is summer heat and humidity over for the northeastern United States?
