Information About the Gloomy Month of April 2011 for Rockford

IT WAS A GLOOMY APRIL IN ROCKFORD. INTERESTINGLY...3.40 INCHES OF
PRECIPITATION WERE RECORDED AT ROCKFORD AIRPORT...WHICH IS ACTUALLY
0.22 INCHES BELOW NORMAL. WHAT WAS NOTABLE ABOUT APRIL...DESPITE THE
SLIGHTLY BELOW NORMAL MONTHLY TOTAL...WAS THE VERY FREQUENT
OCCURRENCE OF PRECIPITATION. AT LEAST A TRACE OF PRECIPITATION
OCCURRED ON 21 OUT OF THE 30 DAYS IN APRIL...WITH AT LEAST 0.01
INCHES RECORDED ON 16 OUT OF THE 30 DAYS AND 11 DAYS WITH AT LEAST
0.10 OF PRECIPITATION RECORDED. THE APRIL NORMAL FOR DAYS WITH AT
LEAST 0.01 INCHES OF PRECIPITATION IS 12 AND THE NORMAL FOR DAYS
WITH AT LEAST 0.10 INCHES OF PRECIPITATION IS 7. THE FREQUENT
PRECIPITATION LED TO PERSISTENT CLOUD COVER FOR MUCH OF
THE MONTH.

DESPITE PROBABLE PUBLIC PERCEPTION THAT IT WAS ALSO UNUSUALLY COOL
IN APRIL...TEMPERATURES WERE ACTUALLY NEAR TO SLIGHTLY ABOVE NORMAL
ACROSS NORTHERN ILLINOIS AND NORTHWEST INDIANA. AVERAGE MAXIMUM
TEMPERATURES AT ROCKFORD WERE 1.4 DEGREES BELOW NORMAL...BUT AVERAGE
MINIMUM TEMPERATURES WERE 3.3 DEGREES ABOVE NORMAL...LEAVING THE
MONTHLY AVERAGE TEMPERATURE  1.0 DEGREES ABOVE THE 1971-2000 NORMAL
OF 47.9. THIS OWES TO THE PERSISTENT CLOUD COVER AND FREQUENT
PRECIPITATION THAT IN GENERAL KEPT DAYS COOLER AND NIGHTS MILDER.
