September weather: Warmer, drier than average

CHAMPAIGN — September was warmer and drier than normal, the second consecutive month for such conditions in Champaign-Urbana.

In fact, there has been only 1.04 inches of rain over the last two months, about 6 inches below the normal for the two months.

For the year, however, precipitation is only about 3 inches below normal.

September ended with 0.68 of an inch of rain, after August's total of 0.36 of an inch.

The driest August-September period was in 1897, when only 0.94 inches of rain fell on Champaign-Urbana.

There was a trace or more of rain on eight of 30 September days, the greatest amount — three-tenths of an inch — on Sept. 20.

Last month was the 11th driest September on record, according to state climatologist Jim Angel at the Illinois State Water Survey. The driest was 1954 with a quarter inch.

September's average temperature was 69.9 degrees, 3.7 degrees above average and the 16th warmest on record, said Angel. The warmest September was 1933 with an average reading of 72.2 degrees.

There were four 90-degree or more reading last month, the highest — 97 degrees — on both Sept. 9 and 10. The lowest reading for the month was 45 degrees on Sept. 14.

The National Weather Service's Climate Prediction Center says there is a better than equal chance for above average temperatures in Illinois in October, and equal chances of above and below average precipitation.
