We are drying out but we are also heating up across the region this afternoon. In fact, portions of the Tri-State (Saline and Hamilton, IL counties) is under a Heat Advisory until 7 PM. The combination of heat and humidity will make it feel closer to the century mark between the hours of noon and 7 PM.
When it comes to the skies above we will be experiencing a mixture of sun and clouds through the daylight hours. Most of the day should remain rain-free with southwest winds keep the tropical-like airmass in place.
