Today: Sunny, hot and humid. High temperatures climb into the lower and middle 90s, with dew points in the 60s. This will create heat index values in the 95°-100° range. Stay hydrated, and don’t forget the sunscreen if you plan to spend any prolonged amount of time outside. It will be a little breezy at times with winds out of the southwest up to 15 mph or greater.
Tonight: A cold front will track in from the south. After 7 p.m. showers and thunderstorms will begin to move in from southern Minnesota. Some of these run the risk of being severe with damaging wind and large hail the main threat. As these track through during the overnight hours, they should be in a weakening phase. Locally heavy rain will be possible in northern Iowa. Farther south, less rain. It will be warm and humid with lows in the 60s.
Wednesday: A few lingering showers are possible before 7 a.m., otherwise expect a partly cloudy sky throughout the day. It won’t be as hot and humid, but still pretty warm for this time of year with high temperatures in the lower to middle 80s.
There is a chance of showers and thunderstorms Thursday night into early Friday, otherwise the weekend looks primarily dry. Temperatures stay warm through the weekend.
