CEDAR RAPIDS, Iowa (KCRG-TV9) -- Active weather is returning to eastern Iowa starting on Tuesday. Heat, humidity, and chances for storms will be in the area through the rest of the week, with northern Iowa having the greatest chance of rain.
Another “ring of fire” pattern is about to setup over the Midwest, as Iowa sits on the edge of a dome of heat centered over the southern United States. The boundary between the cooler and warmer temperatures will look to place itself near northern Iowa and southern Minnesota. This is where rounds of storms will likely develop over the coming days.
The first round of thunderstorms will arrive from the northwest late Tuesday, and more likely Tuesday evening. We’re expecting them to be moving from northwest to southeast, and probably be weakening as they do. This means north and northwestern counties have the highest chance of storms, while our southern counties will have the lowest chance of rain. A few strong storms are possible in our northern counties as well. As of Monday afternoon, a Level 1 (slight) risk of severe weather is in place for areas north of Highway 20.
More rounds of storms are possible Wednesday overnight, and again Thursday night. Northern Iowa and southern Minnesota will again be the focus for these storms as it looks now.
