We hope you are out enjoying the weather this afternoon as temperatures will be in the 60’s and 70’s around the state. This warm weather will continue through tomorrow before a cold front moves through the state late Wednesday evening. As this cold front moves through the state, this will trigger a line of thunderstorms, possibly severe. From the graphic above, the Storm Prediction Center has issued a slight risk of severe storms for western Iowa.
Thunderstorms will begin to develop across northwest Iowa after 4pm Wednesday. Early on, is when the greatest potential for severe weather will be. As the cold front continues through the state, this will lessen the severe threat.
From the graphic above, by 10pm, a line of storms will be entering into central Iowa. This line of storms may have the potential to produce damaging wind gusts and large hail. Also within this line of storms, heavy rainfall totals will begin to add up.
However, as this system begins to move into central Iowa after dark, we will begin to lose the key ingredients to maintain this line of storms. Because of this, by the time the cold front reaches eastern Iowa, storms will be more widespread and just your typical spring time thunderstorms.
The cold front will then exit the state by early Thursday morning leaving behind cooler weather and decent rainfall totals. The heaviest rainfall totals will occur across western Iowa where storms will have the greatest intensity. To recap, only damaging wind gusts and large hail will be expected from any storms that do become severe. There is a slight chance for an isolated tornado or two across central Nebraska tomorrow afternoon, so because of this, our chase team is currently in route to get in position for tomorrow. We will be streaming that chase live on YouTube at (https://www.youtube.com/watch?v=LpCODfoV1Ec) starting at 2pm Wednesday. We will continue to update you on all the very latest so continue to check back here for all the latest updates.
