This Labor Day, Chicagoans should experience another nearly cloudless, warm,
low-humidity day with afternoon highs around 90 degrees. That's a reading 12 degrees
above normal for this date.
In the Great Lakes and Midwest, weather systems not only slow down but are starved of
potential moisture when hurricanes such as Gustav move out of the Gulf of Mexico and
strike the U.S. mainland.
Dry high pressure will continue to dominate northeast Illinois until Gustav moves
inland and allows some moisture to enter this area ahead of a cooling cold front
Wednesday. Temperatures the remainder of the week will be influenced by a
predominantly northeast flow that will keep highs in the 70s.
HANNA: U.S. LANDFALL STILL UNCERTAIN
With peak sustained winds of 50 m.p.h., Tropical Storm Hanna is approaching the
southern and central Bahamas.
It's still very early to determine the eventual movement of this storm as it approaches
the United States: Its potential landfall point ranges from the Florida panhandle to the
North Carolina coast.
Hanna is currently forecast to move northwest, paralleling the east coast of Florida and
intensifying to minimal hurricane strength by Thursday.
