CHICAGO (CBS) — Temperatures will remain cool at the lake for a third day, but it won’t be long before a heat wave sets in.
CBS 2 Meteorologist Mary Kay Kleist says as of 11:20 a.m., it was 73 degrees at O’Hare International Airport, but only 66 at the lakefront, and 68 in Gary, Ind., and Waukegan.
But high pressure is building over Lake Michigan, and the air is sinking and drying, ensuring that conditions remain mostly sunny and completely dry.
The temperature will be 66 degrees with northeast winds of about 10 mph when the White Sox throw their first pitch against the Toronto Blue Jays at 7:10 p.m. Sunset comes around at 8:24 p.m.
The overnight low drops to 57. But the high pressure system that is now just to the southeast of Chicago will still move on its way toward the Eastern Seaboard.
When that happens, a hot and humid flow will begin blowing in from the southwest, as temperatures begin increasing daily.
The high for Thursday is 78, Friday 85, Saturday 88, and Sunday 89 – although the suburbs can expect to see the lower 90s.
The next rain chance comes on Monday, when the high is 87 and thunderstorms may erupt. On Tuesday, the high drops back to 78.
