We can look forward to (or dread) 100+ degree temperatures this weekend.  The last time Chicago reached temperature highs like this was back in the summer of 2012.  That’s 7 YEARS ago!  I still remember carrying an extra shirt to change into after I got to work during that time.  This weekend STAY HYDRATED.  The heat index is expected to reach 105…that’s hot!  It is expected that we will see our hottest temps on Friday.  Use sunscreen or cover up your exposed skin and keep indoors if you can!
