Special Statement
Issued: 3:09 PM CDT Jul. 24, 2017 – National Weather Service

... Heat and humidity will be a concern into mid week...

With high temperatures around 90 degrees, heat index values of
100 to 105 degrees are expected Tuesday afternoon across southeast
Missouri, far west Kentucky and extreme southern Illinois. By
Wednesday, afternoon highs will reach the lower to middle 90s.
When combined with high humidity, these conditions will produce
heat indices of at least 100 to 105 degrees across the entire
region.

Heat index values in southeast Missouri, far west Kentucky and
southwest Illinois could reach around 107 degrees Wednesday
afternoon. A heat advisory may be needed Wednesday if forecast
models continue to indicate these conditions.

Anytime it is hot and humid, take extra precautions if you work
or spend time outside. When possible... reschedule strenuous
activities to early morning or evening. Know the signs and
symptoms of heat exhaustion and heat stroke. Wear light weight and
loose fitting clothing when possible and drink plenty of water.
