Sweating yet? Thursday showers expected as heat advisory ends tonight

News-Democrat

The metro-east remains under a heat advisory until 9 p.m. Wednesday as forecasters are calling for heat index values to reach 103 degrees.

St. Clair, Jefferson, Madison, Monroe, Saint Charles and St. Louis counties are all under the advisory.

“People in the advisory area are advised to avoid poorly ventilated areas and prolonged work in the sun,” the advisory states. “Also, keep plenty of liquids on hand and try to stay in an air conditioned environment.”

The heat index, what hot weather feels like to the body, takes humidity into account in addition to temperature. When the air is more humid, it makes it harder for sweat to evaporate, which means that people’s bodies are less effective at cooling down.

Wednesday night should bring partly cloudy skies with a low around 77 degrees.
