[JUNE 5, 2006]
CHAMPAIGN -- Preliminary data
for Illinois indicate that 3.96 inches of precipitation fell in May
2006, just 0.30 inch below normal. Amounts were an inch or two below
normal in west-central Illinois but normal or slightly higher in the
rest of the state. Spring 2006 (March-May) precipitation was 12.67
inches, 1.40 inches above normal. Last May, precipitation was only
1.77 inches, 2.49 inches below normal.
These figures are provided by Jim Angel, state climatologist with
Illinois State Water Survey,
a division of the Illinois Department of Natural Resources.
Along with the dry March and April last year, spring 2005
precipitation was only 5.85 inches, 5.42 inches below normal,
setting the stage for severe drought last summer across much of the
northern two-thirds of the state. "Fortunately, that is not the case
this year," Angel said.
The 62.4 degree statewide May mean temperature was 0.4 degrees
below normal. Temperatures the first 23 days were 4 degrees below
normal and 9.8 degrees above normal the last eight days.
Cool, wet conditions in early May slowed both planting and
emergence of corn and soybeans. More favorable conditions by the end
of the month allowed completion of corn planting, and soybean
planting was right at the five-year average, according to the U.S.
Department of Agriculture's National Agricultural Statistics
Service. The 53.5 degree statewide temperature for spring was 1.5
degrees above normal.

Temperature extremes ranged from 29 degrees at Mount Carroll on
May 6 to 96 degrees at Bentley on May 29. Kankakee reported the
heaviest one-day precipitation, 3.95 inches on May 25, and
Bourbonnais reported the highest monthly total, 8.84 inches.
"As a result of sufficient precipitation this spring, soil
moisture in all layers is in good shape," Angel said. "In fact,
conditions throughout the state improved so much that the Illinois
Drought Task Force was deactivated on May 24. The National Weather
Service's summer forecast calls for equal chances of temperatures
and precipitation below and above normal. In other words, there is
no increased chance of drought this summer," he said.
