CHAMPAIGN -- The statewide

below the 1981-2010 average. It currently ranks as the 19th-coolest

climatologist at the Illinois State Water Survey, Prairie Research
Institute, University of Illinois.

In comparison, last year's average temperature in July was 81.8
degrees. Illinois was experiencing a heat wave and drought then.
The statewide average precipitation for this July was 2.74 inches,
1.31 inches below the 1981-2010 average. It currently ranks as the
29th-driest July on record.
Despite the dry July, the statewide total precipitation for 2013
stands at 31.4 inches at the end of July and 7.61 inches above the
1981-2010 average. It is the second-wettest January-July. The
wettest January-July was set just a few years ago: 2008 with 32.52
inches.
The rainfall in July was unevenly distributed across the state.
Much of central and northern Illinois was 1 to 3 inches below
average, while southern Illinois was several inches above average.

Mount Vernon reported the highest monthly total precipitation in
the state with 9.42 inches, followed closely by Olney with 9.15
inches. On the dry side, Joliet reported one of the lowest monthly
totals with 0.63 inches, along with 0.72 inches in Pontiac and 0.77
inches in Kankakee.
The wet spring and cool July have both helped to reduce the
effects of the dry weather in July, but conditions will be watched
closely in August.
