CHAMPAIGN -- "Statewide July
temperatures averaged 73.5 degrees F, 2.3 degrees below normal and
the 20th coolest July since 1895. While we had some hot days,
Illinois generally managed to avoid the heat wave experienced out
West during July," says Jim Angel, state climatologist, of the
Illinois State Water Survey, a
division of the Illinois Department of Natural Resources.

"In fact, most Illinois locations had many fewer 90-degree days than
normal. Chicago hit the 90-degree mark four times (three less than
normal), Rockford four times (two less), Moline four times (five
less), Peoria twice (seven less), Springfield once (10 less), Quincy
five times (five less) and Carbondale only nine times (five less),"
says Angel. "Summer rainfall amounts typically vary widely across
the state, and July was no exception. Areas north of Interstate 80
received 5 inches or more, including 12.65 inches at Elburn (Kane
County). While much of the rest of the state received 2-4 inches,
some areas in west-central and southern Illinois received less than
2 inches all month. Statewide July totals averaged 3.67 inches (only
0.16 inches below normal)," says Angel.

The National Weather Service forecast calls for equal chances for
August temperatures and precipitation above, below or near normal.
The August-October outlook calls for an increased chance for above
normal temperatures but equal chances for precipitation above, below
or near normal.
"Right now, the
U.S. Drought Monitor classifies portions of western and southern
Illinois as 'abnormally dry,' so we will be monitoring those areas
very closely," Angel says.
