...EXCESSIVE HEAT WARNING REMAINS IN EFFECT FROM 1 PM THIS
AFTERNOON TO 7 PM CDT SATURDAY...

* TEMPERATURE...Highs in the mid to upper 90s daily, with heat
  index reaching 105 to 110.

* IMPACTS...The heat and humidity may cause heat stress during
  outdoor exertion or extended exposure. The very young, the
  elderly, those without air conditioning, and those
  participating in strenuous outdoor activities will be the most
  susceptible. Also, car interiors can reach lethal temperatures
  in a matter of minutes. Never leave pets, children or the
  elderly unattended in parked vehicles. The extended period of
  high heat and humidity will worsen the effects of heat stress.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

An Excessive Heat Warning means that a prolonged period of
dangerously hot temperatures will occur. The combination of hot
temperatures and high humidity will combine to create a DANGEROUS
SITUATION in which heat illnesses are likely. Drink plenty of
fluids, stay in an air-conditioned room, stay out of the sun, and
check up on relatives and neighbors.

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.
