Incoming rain an interruption in 7 month dry spell
Rain reaches the city by lunchtime, then falls much of the afternoon. But, with maximum amounts of 0.75” predicted—and most area totals under 0.50”—the incoming precipitation represents but a brief break in the ongoing seven month old drought. The rain has been so limited, Chicago’s 2005 growing season now ranks third driest among the 135 on the books since 1871. Only 12.25” which has fallen at O’Hare since March 1—just over half normal and 10.64” below the long-term average.
Skies were completely cloud-free Tuesday allowing 100% of this area’s possible sunshine for the first time in five weeks.
An autumn chill descends on the area Wednesday night with 30s possible in the coldest outlying areas. The cool air contrasts mightily with record heat Tuesday on the Gulf Coast. San Antonio reached 102° Tuesday while Houston baked at 100°, with a 110° heat index.
