Record high temperature for Chicago this Thursday

Unseasonably warm humid air flowed over the Chicago this afternoon with the thermometer reading topping out at 92-degrees at Chicago’s official observing site on O’Hare International Airport – tying the the old record for September 20 set just last year. At Midway Airport the high was 95-degrees – a new record —–surpassing the old record 92-degrees observed at that site last year.
The peak heat Index this afternoon hovered in the 95 to 100-degree range across much of the Chicago area.
Excessive heat – record high temperatures Sunday
Sunday will mark the second consecutive day with afternoon temperatures reaching mid to upper 90s – if we hit our forecast high of 98 degrees, it will establish a new record high for this date exceeding the old record of 96 degrees back in 1957 and also be hottest Father’s Day on record beating the 95 degrees back on June 20, 1971.
Another very important factor to keep in mind is that overnight low temperatures in the “Chicago Heat Island” will probably not drop below 80 degrees both Saturday and Sunday night, allowing little or no relief from the incessant heat. This was a very important factor in the disastrous 1995 Chicago heat wave.
