Isolated parts of the city could see thunderstorms and brief torrential downpours, according to the weather service, but no temperature relief until a cold front approaches Friday evening bringing temperatures dipping into the lower 80s and some likely rain.
To beat the heat, drink lots of fluids, especially water and call 311 for help locating a city cooling center. The city is also advising residents to check on seniors or the disabled during the extreme heat, or call 311 to request a well-being check.
One thing not to do, however, is to open fire hydrants, fire officials are urging, according to CBS Chicago.
“We caution against it, though, because it is very dangerous; for more than just one reason,” Fire Department spokesman Larry Langford told CBS. “The most important is that kids play in that water spray, and they can’t hear cars coming; and the cars creep through that water spray, not knowing there are kids there.”
