High winds and heavy rain buffeted the Chicago area Monday evening as tornado warnings blared across the region.
The National Weather Service said a flooding advisory was in effect until 10:30 p.m. for Cook, DuPage, Kane, Lake and McHenry counties.
As the severe weather leaves, extreme heat will follow. Temperatures in the high 90s will hit Chicago on Tuesday and Wednesday.
The hot weather could set local records. Tuesdays projected high of 98 degrees is just shy of the 99-degree record high for June 14, and Wednesdays high of 97 degrees edges June 15s historic high mark: 95 degrees set in 1994.
But it will feel even hotter. High levels of humidity will make the heat index how the heat is felt by the body warmer, elevating the index to around 105 degrees, Lincoln said.
Ninety degrees in and of itself, although its warm, will certainly feel a lot worse, he said.
The National Weather Service advises Chicagoans to limit outdoor activity, check in on neighbors and family and not leave children or pets in cars.
Its dangerous if people dont use caution, Lincoln said.
Three Chicago women died in a Rogers Park senior housing facility during a heat wave last month. Residents had begged the property managers for days to turn off the heat and turn on the air conditioning amid record-breaking temperatures, residents and family members said.
