Impulses of energy zipping from northwest to southeast across the Midwest on Saturday
triggered scattered thunderstorms just where more rain wasn't needed: eastern Iowa and
southern Wisconsin. Many locations received no rain, but a few spots just west of Madison
and also near Iowa City picked up 1 to 2 inches of unwanted rain. A few of those
thunderstorms swept across Chicago's northern suburbs, though with much less rain.
That pattern of scattered but locally strong, hit-or-miss thunderstorms continues today
across the Chicago area as well as Illinois and surrounding states. Cooler, drier air arrives
late Sunday and the region dries out, at least temporarily.
LAST YEAR’S FATHER’S DAY WAS HOT
Today's warmth won't challenge the 91-degree Father’s Day reading registered here last
year, but thunderstorms might threaten his picnic. Storms will affect 50 percent of the
Chicago area, but there will be several rain-free hours even where storms do hit.
