Weather Summary For Central And Southeast Illinois
National Weather Service Lincoln IL
916 PM CDT Tue Jul 18 2017

Showers and thunderstorms developed ahead of an approaching
disturbance from the northwest, and were sweeping through the
north western portions of the state late evening.

This line of showers and thunderstorms will continue during the
overnight, causing wet weather to impact the northern half of
Illinois. A high pressure system will set up over the central
Plains, producing dangerously hot and humid conditions to spread
into the Midwest. A stationary front will set up along the
northern edge of the heat dome, bringing the chance for
thunderstorms to the region for the second half of the week.

Low temperatures tonight will only dip into the upper 60s to
lower 70s across the region as the warm and muggy airmass takes
hold. Highs Wednesday will surge into the low to mid 90s across
much of Illinois with heat index values between 100 and 105
degrees.
