IT'S OFFICIAL-- FIRST CHICAGO 100S IN SIX YEARS--TEMPS STILL CLIMBING

At 1:08 p.m. this afternoon the city's official thermometer at O'Hare Airport reached 100º. This is Chicago's 61st official 100º day on the books and the city's first since the high of 101º reached on July 30, 1999.

Midway Airport observer Frank Wachowski reported a high of 103º
so far this afternoon that was recorded at 1:45 p.m. CDT. With brisk west southwest winds, there is also no lake cooling with Northerly Island also reaching a high temperature of 100º. With several hours of peak heating ahead, it is likely that readings will surge even higher.

The record high temperature for today is 105º recorded in 1934 and is also Chicago's all-time official record high.
