Eastern Iowa including Cedar Rapids faces heat index readings near 100 degrees with a Heat Advisory in effect through Wednesday evening.

Heat index readings are expected to reach the upper 90s to around 100 during mid-afternoon hours through Thursday, the KCRG First Alert Storm Team said.

"Highs on the thermometer will reach the upper 80s to low 90s, but elevated dew points will push heat index readings into the upper 90s to around 100 during the mid-afternoon hours," the team said in a release.

A chance of scattered showers and storms arrives Friday with rainfall amounts of 0.25 inches or less, according to the same report.

The advisory covers parts of northeast Iowa and southwest Wisconsin, with the peak heat occurring today and tomorrow.
