The combination of record-high temperatures and elevated humidity levels will produce heat index values in the upper 90s to lower 100s Tuesday afternoon across much of southeast Missouri, southwest Illinois, and far western Kentucky. Those planning to be outdoors for extended periods on Tuesday should follow heat safety measures, such as staying hydrated and taking frequent breaks in a shaded or air-conditioned location.
