Severe Storms to Target Midwest, Northeast Through Monday

17 May 2020, 8:02 am

Another round of strong-to-severe thunderstorms could lash parts of the Midwest and Northeast with damaging winds, large hail and tornadoes.

A slight risk (level 2 on a 0-5 scale) has been issued for Sunday across parts of Indiana, Kentucky and Illinois, with damaging winds and isolated tornadoes expected to be the main hazards here.

These storms will budge east for Monday, with the Ohio River valley and the Appalachians potentially at increased risk. A marginal risk (level 1 on a 0-5 scale) is in pace for much of Ohio, Kentucky, Tennessee, South Carolina and Georgia for Monday.

The primary time window for Sunday’s storms will be between 3pm CDT and 9pm, according to the Storm Prediction Center (SPC).




“A few brief tornadoes are possible between about 3 to 9 PM CDT in parts of the Midwest, centered on eastern Illinois and western Indiana,” the SPC said of Sunday’s severe weather threat. “Isolated severe hail and/or wind are also possible this afternoon into early evening across parts of the Northwest, southern Rockies, and mid-to-deep South.”

Strong storms will move west-to-east around an area of low pressure spinning through the Midwest, triggering lines of stronger storms. Cities like Indianapolis; Louisville, Kentucky, Chicago and Fort Wayne, Indiana could all see severe weather on Sunday from this.


After the storms start to dissipate after dark on Sunday, the same system will produce another round of severe weather for Monday. Again, Monday’s storms will only budge east from Sunday’s, meaning Ohio, Kentucky and the spine of the Appalachians could feel the stronger storms by then.

Damaging winds are expected to be the main threat with Monday’s storms, according to the SPC. Instability and enough heat and humidity are the primary limiting factors on Monday, though.

“The environment may become marginally conducive to upscale growing clusters of thunderstorms which may pose a risk for isolated to scattered potentially damaging wind gusts,” the SPC wrote of Monday’s severe weather threat.

A line of stronger storms, leftover from Sunday’s activity, will pull east and bring with it the possibility for damaging winds. That’ll be the near-exclusive threat from Monday’s activity across the Midwest, with the main window for damaging winds coming on Monday afternoon and early evening.

While some storms could hold together after dark on Monday, the lack of heat and humidity will probably dissipate these storms fairly quickly once the sun goes down on Monday night.

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.
