Severe Storms to Target Midwest, Northeast Through Monday
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.
