Special Statement

Statement as of 3:06 PM CDT on August 19, 2017

Expires 5:00 AM EDT on August 20, 2017

... Afternoon heat indices 100 to 105 degrees Sunday and Monday...

High pressure aloft will build over the region through Monday.
This will lead to increasing heat and humidity across the quad
state region. Southeast Missouri and southern Illinois will
experience the worst conditions with heat index values topping out
from 100 to 105 degrees each afternoon. Isolated showers and
thunderstorms may provide some relief for a few locations, but
most of this region will remain dry both days. Elsewhere, across
southwest Indiana and west Kentucky heat index values will top out
from 95 to 100 degrees each afternoon.

With large numbers of people expected to be outdoors Sunday
through Monday, the potential for heat related illness may
increase, especially for those not accustomed to the typical heat
and humidity of late August.

Be sure to drink plenty of water and find opportunities to keep
cool in the shade, when possible.

The heat should move out of the area later on Tuesday, as showers
and thunderstorms usher in cooler air for the middle of next week.
