As a cold front makes its way through Iowa, it will bring with it a good chance for some late afternoon/early evening thunderstorms. These thunderstorms will be capable of producing strong winds and large hail. An isolated tornado or two might also develop. All in all an average summer time storm event but one to keep an eye on.
The Storm Prediction Center has placed much of the state under a slight risk for Tuesday. You can see this in the graphic to the left. An atmospheric cap should hold off most thunderstorm development until the latter part of the afternoon. When and if that cap breaks, thunderstorms will rapidly develop, likely becoming severe and move west to east across the state.
Right now the primary threat would be strong damaging wind gusts. The greatest threat for severe weather, as you can see in the graphic to the right, rests in portions of central and western Iowa. Eastern Iowa might also see severe weather later in the evening, but will also need to watch out for the threat of heavy rainfall. This could cause flash flooding and further aggravate area rivers already swollen by rains earlier this month.
We’ll monitor any changes in the forecast and provide updates on the situation, especially tomorrow.
