Weather Summary For Central And Southeast Illinois

732 PM CDT THU JUL 21 2016
Mostly sunny skies, and oppressive heat and humidity dominated
central and southeast Illinois on Thursday. High temperatures
ranged from 90 to 94 degrees, but high humidity made the heat
index as high as 105 to 115 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 cold
front located over the upper Midwest, will slowly sink south
towards the area over the next couple of days. This will bring a
chance of scattered thunderstorms beginning tonight for parts of
the Midwest, and gradually expanding southward through the Ohio
Valley this weekend.
Low temperatures tonight will drop into the middle to upper 70s
across the Midwest, while highs on Friday will reach the 90s.
