A severe weather outbreak is forecast once again in parts of the storm-weary Midwest, with strong tornadoes and potentially widespread damaging winds. At least some severe storms are also expected in parts of the East as a volatile weather pattern takes shape for the second week in a row.

Happening now

Right now, strong storms are pushing eastward through portions of the Midwest, where a severe thunderstorm watch has been issued for a large portion of Iowa. The main threat from the storms this morning will be damaging winds. You can see where the strongest storms are from the radar below. Any active watches will be highlighted in yellow, and warnings will also be highlighted in red.

Midwest severe weather outbreak threats, timing

In the typically active month of June, severe weather can be a frequent headache for parts of the Midwest and Northeast.

On Wednesday, a dangerous mix of ingredients is setting up for parts of the Midwest, with a springlike strong jet stream and low-pressure system forecast to sweep east into the region.

Wednesday's storms could happen much of the day and night.

The morning round will carry damaging winds, large hail, heavy rain and a few tornadoes. By the afternoon and evening, a line of severe thunderstorms will sweep east from eastern Kansas, Missouri and Illinois through Indiana and Ohio on Wednesday night.

Swaths of damaging wind gusts and tornadoes, some of which could be at least EF2, are expected. This includes some of the same areas hit hard by severe thunderstorms and tornadoes last week.

Cities like Chicago, St. Louis, Indianapolis, Cincinnati, Columbus and Cleveland need to be on alert Wednesday and Wednesday night.

Along with the severe storm risk, there will be a significant risk of flash flooding. This includes places in Chicagoland, as well as northwest Indiana. We could see rainfall rates from storms as high as 2 inches per hour, which can quickly lead to flooding, especially in urban areas. Be mindful of rising water and never drive through flooded roads.

Thursday's threat is in the East

That frontal system reaches the East on Thursday.

Ahead of it, at least scattered thunderstorms could turn severe with damaging thunderstorm wind gusts. The area with the best chance of severe weather on Thursday is shown in the map below.

That could include New York City, Philadelphia, Baltimore and Washington, D.C., among other cities.

Busy June so far

There was a severe weather outbreak across these areas just last week, where over 1,700 storm reports occurred between June 7 and 12.
