Storm Planning and Risk Categories

We continue to track a few areas of thunderstorms that will gradually move into the region early this morning. The first is moving through northeastern Missouri into west-central Illinois, lifting northeast. Then, a line of thunderstorms over central Iowa into northwest Missouri is moving eastward. These storms could become strong, with hail up to the size of quarters and locally strong wind gusts will be possible with them. Storms will be moving quickly, too, with expected storm motions to the northeast around 50 MPH. Make sure to have multiple ways of receiving warnings this morning, and take shelter ahead of the storms if you are outdoors!

Thunderstorms are expected overnight into early Wednesday morning, so lighting and pouring rain are good bets during the morning commute. A scattered severe threat from mainly large hail exists. Plan for unsettled weather to slow the A.M. commute!

Looking ahead to the daytime Wednesday, thunderstorms are likely, but exactly how widespread and how much of a severe threat does continue to be uncertain due to the early morning storms. The storms by mid-late morning into the afternoon will have the potential to be severe, so keep an eye on the latest forecast!

Even apart from storms on Wednesday, southerly winds will be gusty, including as high as 40-50 mph, especially south of I-80 where a Wind Advisory will go into effect for part of that area. Use caution if operating a high profile vehicle.

A reminder on storm risk categories (0 through 5) and what they mean for this event (1 through 3). Check in on the latest forecast through Wednesday and have a means to receive warnings!
