City's shot at 90s Tuesday may be derailed by thunderstorms

It's a pattern that has been repeated here all summer. Every time hot weather attempts to
make an inroad into the Chicago area, debris cloudiness or cooling outflows from
thunderstorms keep temperatures down here.
Once again hot weather is headed east into the Midwest as brisk southwest winds are
slated to sweep into the city Tuesday.
The approaching air mass has produced 90s and 100s in the Plains and lower Mississippi
Valley in recent days, such as the 103-degree record-tying high Sunday at Shreveport, La.
Some recent computer model runs have pegged Tuesday's maximum temperature here
in the upper 90s, but values that high seem unlikely as a combination of leftover
cloudiness and rain-cooled air from overnight thunderstorms slow the warm-up.
TYPHOON FUNG WONG MAY DROP 3 FEET OF RAIN ON TAIWAN
Packing winds as high at 105 m.p.h., Typhoon Fung Wong made landfall on the
east-central Taiwan coast Sunday morning.
The storm is expected to bring as much as 36 inches of rain to the central part of the
island with up to 18 inches on its north and south ends, including the capital of Taipei.
