... Heat and humidity to noticeably return this weekend...
The combination of high temperatures in the lower to middle
90s... along with relative humidity values above 50 percent will
allow heat index values to range from 100 to 105 degrees.
On Saturday... heat index values over southern Illinois and
southeast Missouri will likely range between 100 to 105 degrees
between 3 PM and 7 PM CDT. The focus of these elevated heat index
values will shift into the southern Purchase and pennyrile areas
of west Kentucky Sunday afternoon.
The duration and intensity of the elevated heat index values may be
impacted by any cloud cover and precipitation that occurs with
weather systems moving southeast toward the quad state region.
However... the heat and humidity will still make it very
uncomfortable for those working or playing outdoors this weekend.
If you are particularly sensitive to heat and humidity... then make
plans to stay out of the heat. Be sure to drink plenty of
water... take frequent breaks and wear light and loose fitting
Cooler weather will return back to the quad state region on Monday.
