CHAMPAIGN -- October was cooler
and wetter than normal, according to Jim Angel, state climatologist
with the Illinois State Water Survey at the University of Illinois
The statewide average temperature was 52.2 degrees, 1.9 degrees
below normal. Most of the state reached lows of 32 degrees, and much
of central and northern Illinois was down to 28 degrees or colder,
signaling the end of the growing season for most outdoor plants.
The statewide average precipitation was 3.9 inches, 0.7 inches above
normal. The wettest area of the state was between Quincy and
Champaign, where precipitation totals ranged from 4 to 7 inches.
Some of the driest areas were in southern Illinois south of
Interstate 64 and in northern Illinois north of I-80. Some of that
area had precipitation totals of less than 3 inches.
The statewide average precipitation for January-October was 27.1
inches, nearly 5.8 inches below average. This made it the
15th-driest January-October and virtually tied with 2005. The driest
was in 1901 with 22.0 inches. The second-driest was 1988 with 22.1

The statewide average temperature for January-October was 58.9
degrees, 3.4 degrees above normal. That made it the second-warmest
on record. The warmest was 1921 with 59.2 degrees.
"Soil moisture and stream flows in many areas have begun to
recover from this summer's drought, thanks to the rains and cooler
temperatures. We should see further improvements in November," Angel
