CHAMPAIGN -- Precipitation was
near normal for the month of October in Illinois, at a statewide
average of 3.2 inches. The long-term average, or normal, for October
is 3.26 inches of precipitation, according to Jim Angel, state
climatologist, at the Illinois State Water Survey.
Most of the precipitation fell in the last few days of the
month. The heaviest amounts were in Cook, Will and Kankakee
counties, along with some areas in far southern Illinois. The
largest reported monthly total was 6.79 inches at Bourbonnais.
Many sites across northern and central Illinois reported their
first snow of the season in October. The highest monthly
snowfall total was at Mendota with 3.5 inches. Several more
sites reported 1 to 2.5 inches of snow for the month.
Temperatures were just 0.3 degrees below normal with a
statewide value of 54.3 degrees. However, the first half of the
month was 5.5 degrees above normal, while the second half was
5.9 degrees below normal. Most of the state saw temperatures
dropping below freezing for the first time this fall on Oct.

"The late October rains were large enough and widespread enough to
help recharge soil moisture after the exceptional dryness of the
last three months," Angel said.
