[April 07, 2007]
After a cold February, the
pendulum swung the other way, giving Illinois March temperatures
averaging 47.6 degrees statewide, 6.5 degrees above normal and the
sixth-warmest March on record since 1895, according to the state
climatologist, Jim Angel. Several cities, particularly
Champaign-Urbana, set or tied daily high temperature records.

March 13 records were exceeded at Chicago, with 73 degrees;
Rockford, at 74 degrees; and Peoria, at 78 degrees; and tied at
Champaign-Urbana, with 78 degrees. March 14 records were tied at
Springfield, with 75 degrees, and exceeded at Champaign-Urbana, with
78 degrees. The March 25 record was exceeded at Champaign-Urbana,
where it was 80 degrees. Statewide, March precipitation was 3.43
inches, 0.22 inches above normal, based on preliminary data. Most of
the heavier rainfall, 3-6 inches, fell over the northern half of the
state. The southern half of the state was drier, with rainfall
totals of 1-3 inches in most areas.
National Weather Service outlooks for April-June and
July-September call for both temperatures and precipitation having
equal chances of being above, below or near normal.
"Those very warm March temperatures may have fooled us -- and
plants -- into thinking spring was here to stay, but wintry
temperatures returned in early April," said Angel.

"April is usually when the last freezing temperatures occur:
northern Illinois, April 28; central Illinois, April 14–21, and
southern Illinois, April 7. If you're thinking of planting tender
annuals, add about two weeks to those dates," Angel said.
