Heat Index exceeds 110-degrees at many Chicago area airport locations Friday afternoon

Oppressive heat hovered over the Chicago area this Friday afternoon with high temperatures in the low to middle 90s and dew-points in the upper 70s to lower 80s leading to heat index values warming well above 110-degrees at many area airport locations. The dew-points are the real story behind the high heat index values, and the 81-degree low temperatures at both O’Hare and Midway set a new record high low temperature for this date at both locations.

Highest heat indexes were 119-degrees at Schaumburg and 116-degrees at Joliet. Midway hit a heat index of 113-degrees and Chicago’s official station at O’Hare registered 107-degrees.
