Special Statement
Issued: 1:44 PM CDT Aug. 21, 2017 – National Weather Service

... Heat index values from 100 to 105 continue this afternoon in
southern Illinois and southeast Missouri...

Heat index values will remain in the 100 to 105 degree range this
afternoon across most of southern Illinois, southeast Missouri,
and The Purchase area of west Kentucky. Across the pennyrile
region of west Kentucky and southwest Indiana, somewhat lower heat
indices from 95 to 100 are expected once temperatures recover in
the wake of the eclipse. Actual air temperatures will rise back
into the lower 90s.

Heat index values will fall through the 90s after 6 PM.

If you are planning to be outside today for an extended period of
time, be sure to keep hydrated by drinking plenty of water. Look
for opportunities to get out of the heat from time to time, and
get into the shade or in an air conditioned building.

Keep watch on those persons who may be unaccustomed to the heat
and humidity.

623 am CDT Mon Aug 21 2017

... Heat index values 100 to 105 expected this afternoon over part
of the quad state region...

Hot and humid conditions will be the rule today, regardless of the
passage of the solar eclipse through the region this afternoon, as
air temperatures top out in the lower 90s.

Heat index readings are expected to reach 100 degrees by noon over
southeast Missouri. As temperatures rise into the lower 90s, heat
index readings above 100 degrees will build northeast across
southern Illinois and The Purchase area of west Kentucky, west of
the Land Between The Lakes. Heat index values at or above 100
degrees will likely persist through 6 PM CDT today.

The rest of the quad state region will see heat index values top
out in the upper 90s this afternoon.

If you are planning to be outside today for an extended period of
time, be sure to keep hydrated by drinking plenty of water. Look
for opportunities to get out of the heat from time to time, and
into the shade or in an air conditioned building.

Keep watch on those with you that may be susceptible to or
unaccustomed to the heat and humidity, typical for late August in
this region.
