Weather Summary For Central And Southeast Illinois
National Weather Service Lincoln IL
240 PM CDT THU JUL 21 2016
Mostly sunny skies, and oppressive heat and humidity dominated
central and southeast Illinois this afternoon. Mid afternoon
temperatures were in the lower 90s, but with the high humidity,
heat index readings were near 110 degrees.
A large upper level high pressure ridge will keep an area of high
heat and humidity in place across the Midwest through the upcoming
weekend. This will produce dangerously hot conditions each day,
from the late morning through the early evening hours. A weak cold
front located over the upper Midwest this afternoon, will slowly
sink south towards the area over the next couple of days. This
will bring a low chance of scattered thunderstorms beginning
Friday over northern Illinois, and gradually expanding southward
through southern Illinois this weekend.
Low temperatures tonight will drop into the middle to upper 70s
across the Midwest, while highs on Friday will reach the 90s.
