Thunderstorm "debris" cloudiness -- remnants of dissipating thunderstorms that
flared to our west Thursday -- has spread across the area overnight. It's a development
that might bring an errant shower or two to parts of the area -- but is more likely to
reduce the amount of sun blazing down on the area Friday, possibly preventing a fourth
day of 90-degree temperatures over much of the area. Highs Thursday fell just short of
90 degrees at O'Hare (89 degrees) but surged to 91 degrees for the third consecutive
day at Midway. Other area highs included 93 degrees near U.S. Cellular Field on the
South Side and 92 degrees at New Lenox and at Griffith, Ind.
The storms which erupted to Chicago's west Thursday over Iowa and Nebraska may
hold clues to the weather ahead here. Drenching thunderstorm rains, which fell at the
rate of 1.90 inches in just 35 minutes near Table Rock, Neb., and 1.76 inches at the
National Weather Service Office at Hastings in just 25 minutes, caused widespread
street flooding.
