Weather Summary For Central And Southeast Illinois
National Weather Service Lincoln IL
432 AM CDT Thu Jul 20 2017

Partly to mostly cloudy conditions were seen across central and
southeast Illinois, through the overnight hours. Temperatures
across the area early this morning, ranged from 69 degrees at
Danville, to 78 degrees at Mattoon.

An area of showers and thunderstorms will persist across the northern
portion of Illinois and southern Wisconsin today. This area of
storms is traveling along a frontal boundary positioned over
northern Illinois and back into Iowa. As this boundary remains
stationary over the next couple of days, heat and humidity will
continue to be the major impact to the Midwest. In addition to the
hot conditions, some thunderstorm development will be possible as
moisture in the air combines with high temperatures to provide
unstable conditions.

High temperatures today, will range from the upper 80s across
Wisconsin, to the middle to upper 90s elsewhere. Heat index
values will approach 110 degrees during the late afternoon hours.

Overnight low temperatures, will range from the middle 60s across
Wisconsin, to the middle to upper 70s elsewhere.
