Multiple flood watches have been posted for parts of the Upper Midwest and east into the Ohio River valley, as a stagnant storm system will lead to more heavy rain across the water-logged region.

A slow-moving deep trough of low pressure is continuing to kick up shower and storm chances ahead of it across the Upper Midwest.

Here’s a look at the watches, as of Wednesday morning:

A cluster of showers and thunderstorms will move south and east, drying out Minnesota while increasingly soaking the mid-Mississippi River valley. Places like St. Louis, Missouri and Quincy, Illinois could see more than six inches of rain before the parent storm system spins each later this week.

With a deep surge of tropical moisture from the Gulf of Mexico, thunderstorms will be able to produce very heavy rainfall. One computer forecast model, shown below, shows the possibility for over six inches of rain due to multiple rounds of intense storm-driven rainfall:

Chris doesn't remember a time when that he didn't love the weather. When he was five years old, he wrote his first words, "Partly cloudy", in Ms. Benn's kindergarten class. According to Chris, it's been a love affair ever since, from teaching himself how to read forecast models at age 12, to landing at WeatherNation. Growing up in Greenwich, Connecticut, he started to go after his lifelong drea... Load Morem of becoming a meteorologist by predicting whether or not there would be snow days - turning him into Greenwich High School's "defacto weatherman". He turned that snow day-predicting website into a front page story a local newspaper, which in turn earned him a look at WABC-TV in New York, where Chris did the weather live on-air at the age of 16. He attended Boston University, where he continued being a "weather nerd", performing weather updates on the campus radio and TV stations, and doing the daily forecasts for the student newspaper. Following his studies at BU, Chris worked at Mile High Sports and ESPN Denver for four years while pursuing his certification in Broadcast Meteorology from Mississippi State University. Chris is a huge sports fan, rooting for the Rockies, Nuggets, Broncos, Avalanche and UConn. He frequently find links between sports and weather, including an investigative analysis he did in 2013, finding trends between Peyton Manning's play and game time temperature (he doesn't like the cold). Chris also enjoys running, playing any sport, socializing and periodically overeating at all-you-can-eat buffets.
