Illinois State Climatologist Jim Angel said, as of June 29, the statewide average rainfall for June was 9.37 inches, more than double the monthly average of 4.2 inches for June.
Chicago might not have set any records for heat or rainfall last month, but May was still warmer and wetter than normal, despite the chilly end to the month.
Hurricane Isaac could affect the Labor Day holiday in the Chicago area with heavy rain.
Going into the weekend, this was the third driest July on record, dominated by a week of sunny, sweltering days where the temperature exceeded 100 degrees in some areas.
It’s officially the rainiest day since they began keeping records in 1871, according to the National Weather Service.
More thunderstorms could produce very heavy rainfall and even quarter-sized hail early Sunday morning, leading into another rainy, cloudy day.
The showers and thunderstorms that moved into the Chicago area Wednesday are expected to continue, prompting a flash flood watch to be issued.
Conditions are sunny and May flowers are in bloom at last, and with bone-chilling rain, overcast skies and even a late-season snowstorm, few in Chicago were likely sorry to see April go.
A new record for April rainfall has been set in Illinois. This month beats the previous record of 7.13 inches set in 1957.
It was dry too in some areas of Illinois.
