...Dangerous Heat Today and Saturday... .Heat indices of 100 to 110 will be common across the area this afternoon with values of 95 to 105 expected Saturday. These indices will be the result of high humidity levels and temperatures topping out in the 90s. Just one-half hour exposure to this high heat could result in heat related illnesses. Prepare now for the heat. Avoid exposure during the afternoon and check in on family, friends and pets. The young and elderly are especially susceptible to impacts from heat. ...EXCESSIVE HEAT WARNING REMAINS IN EFFECT FROM NOON TODAY TO 7 PM CDT THIS EVENING... ...HEAT ADVISORY REMAINS IN EFFECT FROM 7 PM THIS EVENING TO 7 PM CDT SATURDAY...

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