Also, parked vehicles will become dangerously hot within
minutes.

Precautionary/preparedness actions...

A heat advisory means that a period of hot temperatures and high
humidity is expected. This combination will lead to possible
heat illnesses. Drink plenty of fluids, stay in an air-
conditioned room, stay out of the sun... and check on relatives
and neighbors, especially the elderly.

Take extra precautions if you work or spend time outside. When
possible, reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

To reduce risk during outdoor work the occupational safety and
health administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency, call 9 1 1.

Special Statement
Issued: 10:06 PM CDT Jul. 21, 2017 – National Weather Service

... Areas of thunderstorms to continue through 1 am...

Thunderstorms are redeveloping along an elevated boundary in northeast
Iowa and northwest Illinois. These storms may train or follow each other,
which may result in some additional locally heavy rainfall amounts up
to 1 inch, though most amounts will tend to be much less than a half
inch. Locations that pick up the heaviest rain amounts may experience
additional water issues due to the already saturated ground. The strongest
storms may produce small hail, possibly up to the size of pennies. Gusty
winds up to 40 mph may also occur.
