CHICAGO (CBS) — The summery sunshine of the midday hours Tuesday may be replaced by storms later in the afternoon, although the chance is only 30 percent.
CBS 2 Meteorologist Mary Kay Kleist reports it was already 80 degrees at O’Hare International Airport at 11:20 a.m. Temperatures were only slightly lower at Midway and the lakefront, both of which came in at 78 degrees.
Meanwhile, humidity is only 26 percent, and the dry lower atmosphere will keep some wispy showers making their way south from Wisconsin from hitting the ground.
But moisture will increase as a storm system now over the Minneapolis area sweeps through. Kleist says between 5 and 10 p.m., there will be a 30 percent chance of showers and thunderstorms – meaning that anywhere you stand, there will be a 3 in 10 chance that it will be raining.
The storms will not come until after the White Sox game. For the first pitch at 1:10 p.m. for the Sox’ game against the Detroit Tigers at U.S. Cellular Field, Kleist says the temperature will be 80 with southwest winds at 10 to 20 mph.
For the day, the high is 84 degrees. But following the storms, a passing the cold front will cut the high temperature Wednesday to 65.
The high for Thursday is 75, Friday 81, Saturday, 84, Sunday 83 with another chance of storms, and next Monday 68.
