...EXCESSIVE HEAT WARNING REMAINS IN EFFECT UNTIL 8 PM CDT THIS
EVENING...

* TEMPERATURE...Despite rain-cooled temperatures in the 70s this
  morning, skies will become partly to mostly sunny this
  afternoon. As a result, high temperatures will once again climb
  into the middle 90s.

* HEAT INDEX...With dewpoints well into the 70s, afternoon heat
  index readings will range from 105 to 110 degrees.

* IMPACTS...The effects of heat are cumulative, and worsen the
  longer a heat wave lasts. People without access to air
  conditioning, or those that are working or playing outdoors,
  are most likely to be impacted by the heat. Heat exhaustion or
  heat stroke are possible if work or play is too strenuous.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

An Excessive Heat Warning means that a prolonged period of
dangerously hot temperatures will occur. The combination of the
heat and high humidity will 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.

Young children and pets should never be left unattended in
vehicles under any circumstances. This is especially true during
hot weather when car interiors can reach lethal temperatures in a
matter of minutes.
