An Excessive Heat Warning is in effect for the central and southern Minnesota and parts of western Wisconsin, including the entire Twin Cities metro, through Wednesday evening.

The Twin Cities broke a long-standing record high temperature today, reaching 98°, with heat index values that got as high as about 114° in the Twin Cities. The previous record high temperatures was 97°, set back in 1898, and tied in 1971. Tonight, lows fall into the upper 70s to around 80° for the Twin Cities metro. When you don’t even have a chance to cool off overnight, it makes it very hard for your body to recover without air conditioning. Heat index values overnight will be in the mid-90s to mid-80s overnight into tomorrow morning. With highs in the upper 90s, and dew points well into the 70s, it feels like 105° to 110° again Wednesday afternoon and evening.

That means it is another day to stay inside during the afternoon and evening. We start to feel a little relief for the start of the State Fair Thursday. It will still be warm and muggy for the first two days, with highs in the upper 80s to around 90°. A front pushes across the state Friday, and there could be a few thunderstorms with it. By the weekend, temperatures drop into the upper 70s and low 80s, which is great for the fair!
