CHICAGO - Aug. 18 is the last day that Chicago posted a temperature surplus. Since then, every day has been at or below normal. Yesterday was no exception with a high of only 76°.

However, there was a bump in the direction that we’re headed over the next several days.

Chicago weather forecast

What to expect:

Today under skies that will become mostly sunny, highs should reach 80°. It will be cooler near the lake with some penetration of that cooler air inland late in the day.

Tonight will be mainly clear and pleasant with lows in the 60s.

Tomorrow will be mostly sunny and warm with highs once again in the low 80s. Then some even warmer air arrives with highs in the mid to upper 80s on Friday, Saturday and Sunday (possibly into early next week as well.)

There is very little chance
