Severe Weather & Heavy Rain Tuesday Across Northern Iowa

Iowa Severe Weather Outlook

The heat and humidity is building back into the state this week, and this will provide the fuel for afternoon and evening thunderstorms. An advancing cold front, which will not really cool us down any, will begin to approach northwest Iowa by Tuesday afternoon. This will trigger off a line of thunderstorms from southwest Minnesota into northwest Iowa.

Storm mode is expected to trend towards bands through the afternoon and into the evening, which would mean hail and
locally damaging winds would appear to be the main severe risks. Still, a tornado or two could occur in conjunction with any
stronger/rotating cells. The severe risk will diminish into the overnight hours as we lose the heating of the day.

Heavy rain also appears to be a primary risk as well Tuesday, which is why there is a slight risk of excessive rainfall across northern Iowa. Where the heavy rain falls will depend on where the location of the frontal boundary sets up. Wherever this boundary sets up, one to two inches of rain appears likely, with isolated higher amounts.
