CHAMPAIGN -- A cold and wet
first half of April has farmers still waiting to get into the fields
and homeowners waiting to get into their gardens. Temperatures in
the first two weeks of April were 4.5 degrees below normal, and
precipitation was 58 percent above normal. Many places in northern
Illinois reported measurable snowfall from an April 5-6 storm,
according to Jim Angel, state climatologist, of the
Illinois State Water Survey.
The statewide average temperature for April 1-14 was 44 degrees,
while the statewide average precipitation was 2.7 inches. This
followed a March that was both warmer and wetter than normal. The
statewide average temperature in March was 43 degrees (2 degrees
above normal), while the statewide average precipitation was 4.2
inches (30 percent above normal).
The coldest April on record in Illinois had an average
temperature of 43 degrees, set in 1907, while the second-coldest was
in 1926 with 45 degrees. While temperatures are expected to be
warmer in the second half of this month, it may still end up being
one of the colder Aprils on record.
"Besides the generally cold, wet conditions, people should be
concerned about the risk of frost damage to plants," said Angel.
"The average date of the last spring frost ranges from April 7 in
far southern Illinois to mid-April in central Illinois to late April
in northern Illinois. Adding about two weeks to that date greatly
reduces the chance of seeing freezing temperatures."
