Continuing our string of days featuring a threat for severe weather, the Storm Prediction Center has posted a slight risk for the entire state of Iowa on Monday. This threat coincides with a warm front that will push through the state, potentially triggering thunderstorms.
If storms develop, shear profiles are supportive of supercells and possibly tornadoes. But there’s a catch. A strong cap is expected to take shape over Iowa, which would limit severe thunderstorm development on Monday afternoon and could prevent explosive development until much later in the day, even closer to sunset.
The fortunate thing for storms chasers is we are currently enjoying the longest days of the year. Hopefully that will create a window of opportunity across Iowa. We will continue to monitor the latest forecasts in association with this storm system and will bring you updates as Monday draws closer.
