SE Wisconsin weather: Heatwave on the way, 'Excessive Heat Watch' to go into effect Wednesday

Storms may develop late tonight along the edge of extreme heat. We call these "Ring of Fire" storms.
and last updated

******EXCESSIVE HEAT WATCH FROM 11AM WEDNESDAY UNTIL 8PM THURSDAY FOR ALL OF SE WISCONSIN***

Skies will be partly cloudy tonight with lows in the 60s.

Tuesday will be warm as the heat starts to build. With a southeast wind, lake-side areas will top out in the upper 70s, while inland spots will warm into the upper 80s. More clouds, and a few isolated showers, are possible for northern areas, while farther south we stay dry with lots of sun.

The hottest weather of the season is on the way Wednesday and Thursday. Plan to reduce time and activity outdoors. Stay hydrated, take special care of pets, and check on neighbors and friends who don't have A/C.

Wednesday temperatures will quickly warm into the 90s area-wide. Factoring in the humidity feels like temperatures will range from 100-110°.

Thursday will be another hot day, but it looks like Lake Michigan may help keep areas near the lakeshore a little cooler. As of now, near the lake it looks like highs will top out in the mid to upper 80s, while inland spots still make it into the 90s. With humidity still high, heat index values will range from 95-105°.

Temperatures will start to cool Friday, and the 70s return by the upcoming weekend.
