...EXCESSIVE HEAT WARNING IN EFFECT UNTIL 8 PM CDT SATURDAY...

The National Weather Service in Tulsa has issued an Excessive

Heat Advisory is no longer in effect. 

* TEMPERATURE...High temperatures ranging in the mid 90s to around
  103 degrees will continue this afternoon and again Saturday
  afternoon across eastern Oklahoma and western Arkansas. The
  temperatures, combined with high humidity, will create dangerous
  heat index values in the 108 to 113 degree range. Overnight
  temperatures will provide little relief from the heat,  
  especially in the more urban areas. 

* IMPACTS...The combination of hot temperatures and high 
  humidity will combine to create a dangerous situation in which 
  heat illnesses are possible. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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 911.
