There will be several rounds of storms on Wednesday to contend with. The first comes early in the morning, which could bring large hail to parts of north-central Iowa around and shortly after sunrise before they transition to a heavy rain threat. Our attention then turns back towards the I-35 corridor for the early afternoon hours, where a second line of storms could develop and track eastward, bringing with them large hail, damaging winds, and perhaps a tornado threat. Exactly where these storms form and their severity will be driven by how quickly the morning storms can clear. Stay weather aware tomorrow!
In addition to the severe storms, heavy rainfall will also be possible with this activity. Many locations across the area have already seen ample rainfall over the past couple of weeks and repeated activity could lead to localized instances of flooding.
With the risk for another severe weather event looming for tomorrow afternoon, now is the time to dust off your severe weather preparedness plan. Double check your that your safe places are accessible, make sure your phone can receive weather alerts, and be prepared to adjust any of your plans.
