After a warm and increasingly humid weekend, Chicago is slated for a major- league
burst of heat and humidity Monday with readings expected to reach the middle 90s—
the hottest weather so far this summer. Before the heat moves in Monday afternoon,
the city may have to deal with several bouts of showers and thunderstorms that could
dump some heavy rainfall here mainly Sunday night and early Monday.
Once the heat arrives on gusty southwest winds, readings should quickly surge into
the middle 90s, and, combined with a dose of Gulf Coast-level humidity, heat
indexes could approach 100 to 105. So far this summer the city has not seen a
temperature higher than 91 degrees, something that has only happened twice in 80
years at Midway Airport: first in 1979 and again in 2000.
The heat should quickly retreat as cooler northeast winds set in by Wednesday and
dominate through the rest of the week.
DENVER SHATTERS MORE HEAT RECORDS
A 130-year-old high-temperature record fell in Denver Saturday, when the mercury
hit 103 degrees, besting the old record of 100 recorded in 1878. Denver has logged
an unprecedented 21 consecutive 90-degree-plus days, with more expected. The
city’s previous string of 90s was 18 in 1878 and 1901.
