... Hot and humid today...

Temperatures will rise quickly this morning leading up to the
solar eclipse. During the eclipse, temperatures may fall a couple
degrees, but will then rebound by late this afternoon into the
lower 90s. With expected humidity levels, the heat index just
before the eclipse could reach the mid 90s over western portions
of south-central Kentucky near the location of solar totality.
While the heat index may fall a couple degrees during the eclipse,
it will rise quickly again afterward, reaching the mid 90s across
much of central Kentucky and south-central Indiana, with upper
90s in some locations mainly along and west if Interstate 65 by
late afternoon.

With many people expected to be outdoors today for the eclipse,
the potential for heat related illness may increase. If you will
be outside for a long time today, drink plenty of water and find
opportunities to stay in the shade if possible.

... Hot and humid conditions expected on Monday...

High pressure continues to build into the region. This will bring
dry and increasingly hot weather to the region on Monday.

High temperatures Monday are expected to warm into the upper 80s
to the lower 90s. Afternoon dewpoints are expected to be in the mid
and upper 60s which will produce afternoon heat indices in the 95
to 100 degree range. The highest heat indices are expected
between 1 and 6 PM local time.

With a large number of people expected to be outdoors on Monday due
to the upcoming solar eclipse, the potential for heat related
illness may increase. This will be especially true for those not
accustomed to the typical heat and humidity of late August in the
Ohio Valley.

If you are planning to be outside for a long period of time on
Monday, you should dress accordingly by wearing lightweight and
light colored clothing. Be sure to drink plenty of water and find
opportunities to keep cool in the shade if possible.

Stay tuned to NOAA all hazards weather radio and your local media
for the latest weather conditions.
