After severe storms moved through the southeast part of the state Monday night, another complex of severe storms will be back in our forecast Wednesday. Large hail and damaging wind gusts along with a threat for a few tornadoes will be possible during the afternoon and evening. Potential for a strong tornado and hailstones of greater than 2 inches could also develop across parts of Iowa into northern Illinois.
Storms will develop this evening after midnight across southwest Iowa. These storms will mainly stay across southern Iowa. A few of these storms may be strong to severe with hail the primary threat. These storms will then begin to dissipate around mid morning.
We will get a break in the rain during the late morning to afternoon. This will allow for instability to build back into the state as a warm front will begin to move north across the state. This warm front will be the focal point for storms later on in the afternoon. The atmosphere should be capped through the afternoon, but as soon as storms fire, they will rapidly intensify.
Storms appear to develop in central Iowa around or shortly after 7pm. These cells should remain isolated along the warm front. These storms will be capable of producing tornadoes, which a few of them may be strong. This is why the storm prediction center has placed central and eastern Iowa under an enhanced risk. The Storm Prediction Center is also monitoring the potential to upgrade this enhanced risk to a moderate risk. As storms move to the east, they will begin to cluster together, and will form a damaging wind threat across eastern and western Illinois.
Wednesday will be a day that you will want to be weather aware, and make sure you are paying close attention to the weather. Our chase team will be out tomorrow tracking these storms. Continue to follow the Iowa Storm Chasing Network for the very latest updates.
