Illinois August and summer
hotter than average in 2002
[SEPT.
5, 2002]
"It
was the 24th warmest August and the 14th warmest summer in Illinois
since 1895," says Jim Angel, state climatologist with the
Illinois State Water Survey, a
division of the Illinois Department of Natural Resources.

"August also was the 24th wettest since
1895, with a statewide average of 4.36 inches (119 percent of
average), despite dry conditions in southern Illinois south of I-70,
where August rainfall totals dipped below 2 inches (60 percent of
average)," says Angel.
The warmest and coldest temperatures
were at Grand Tower (104 on Aug. 5) and Mount Carroll (48 on Aug.
18). Rockford reported the largest one-day rainfall total, 5.92
inches on Aug. 22, a little more than half the largest monthly
total, which was 11.44 inches at Barrington.
"Statewide, temperatures averaged 75
(1.4 degrees above average) for August and slightly higher (75.7, or
2 degrees above average) for summer (June-August)," says Angel.

"Heavy August rains over large portions
of central and northern Illinois, combined with heavy rains late in
July, have eliminated any precipitation deficit caused by the dry
weather that began in June. Rainfall in these areas was 110 to 120
percent of average for the entire summer. These rains have been
timely for the final development of corn and soybeans and have left
soil moisture and stream flow in good shape. However, southern
Illinois has received little rainfall, with southeastern Illinois at
59 percent of average for August and 57 percent of average for
summer," continues Angel.
"National
Weather Service forecasts are calling for a return of warm, dry
conditions over the next two weeks, so southern Illinois should not
expect relief any time soon. The good news about heat in September
is that the days are getting shorter and the humidity is dropping.
This means the ability of the weather to remain hot diminishes with
each passing week," concludes Angel.
