ST. LOUIS — For the second day in a row, temperatures climbed above 90 degrees in St. Louis. A record high temperature of 94 degrees was set at St. Louis Lambert International Airport Wednesday afternoon. The old daily record was 91 first set in 1914 and again in 2011. It is also the earliest it has been this warm in St. Louis. Previously, on May 15th in 1944, the temperature climbed to 94.
After last week's widespread two to three inches of rain along with the trees leafing out, humidity levels climbed to uncomfortable levels again Wednesday afternoon. Heat index values climbed above 100 in a few spots.
The heat index is expected to be in the mid to 90s to near 100 again Thursday afternoon. With such a quick surge of heat and humidity, our bodies have not had the chance to get acclimated to hot weather yet.

Remember, high heat coupled with high humidity increases the risk for heat-related illness.
Limit your time outdoors during the hottest time of day. Wear loose, light-colored clothing and try to get into the air conditioning as often as possible. Drink plenty of water. Keep pets inside during heat like this and remember to check on elderly family and friends along with your children.
If you're outside this week and not sweating, that could be your first sign that you may be getting overheated and/or dehydrated.
