Two words: Heat index.
But for those two words, Chicagoans might be dealing with a sticky, but more manageable 97-degree high Friday.
Instead, thanks to the heat index — the combination of heat and humidity — it’s expected to feel more like 105 in the city, according to the National Weather Service.
It’s kind of like the opposite of the “wind chill factor.”
Even though we might not technically reach 100, it’s sill likely to be the hottest day of the year so far. On June 7, the high reached 96, the weather service said.
Here’s some advice you should heed: “You want to stay inside, but drink plenty of water if you have to be outside,” said meteorologist Amy Seeley. “It’s mostly common sense stuff. Take breaks if you have to work out in the sun.”
By Saturday, it gets a bit cooler — highs in the upper 80s to lower 90s. And on Sunday, expect a high in the low to mid 80s.
