If you have spent any amount of time outdoors in the past few days, you have noticed the heat and humidity, or as we call the air you can wear. This has caused afternoon pop-up showers and thunderstorms to develop the past couple of afternoons. By Thursday, a cold front will be moving through the state.
This cold front will drop the humidity levels significantly by the weekend, but it will also provide the chance for strong to severe storms across the eastern two-thirds of the state. Storms will develop along this cold front after 4pm, stretching along a line from Decorah to Des Moines. One major issue with storm development will be the strong cap that will be in place. This could prevent storms from developing, but storms do appear have the best chance to develop across northeast Iowa.
Main threats with any storms that do become severe will be large hail and damaging wind gusts. Low level shear appears to be weak enough that the tornado potential will be very low.
When storms develop, track them on our new FREE Storm Hunter WX app, now available on the Android and iTunes store.
