A band of clouds and a few showers were moving from west to east
across central Illinois this morning. At late morning, the front of
the cloud band was just pushing past the I-55 corridor, while the
clouds were beginning to clear west of the Illinois River.
Temperatures across the area at 11 a.m., 79 degrees at Lacon, to 88
degrees at Mount Carmel and Olney. Heat index values across the area
were generally in the 90s and low 100s south of the I-74 corridor,
with 80s observed to the north.
A cold front in Iowa will slowly push southeastward into northwest
Illinois today. Scattered thunderstorms will accompany the front. As
a result of the increased cloud cover and storms, temperatures across
Iowa, northern Missouri, and north-central Illinois will be cooler
today. Further south and east across the remainder of the region, it
will be another very hot and humid day with heat index values once
again rising well above 100 degrees.
High temperatures today, will range from the mid 60s in northern
Wisconsin, to the upper 90s in southwest Missouri. Heat index values
will top out in the 100 to 110 degree range across central and
southern parts of Missouri and Illinois today.
Low temperatures tonight, will generally be in the mid 60s to lower
70s across the Midwest, while 50s will be more common in northern
Iowa and across Wisconsin.
