An isolated thunderstorm can’t be ruled out over the northern two-thirds of Oklahoma this afternoon and evening. Any thunderstorm will be capable of strong winds, however any rain that falls could evaporate before hitting the ground due to the dry conditions at the surface. Otherwise, the heat wave will be relentless all week long and lasting through the end of next week, at least. A heat advisory remains in effect. I do see this advisory being extended to correspond with the excessive heat warning in effect for eastern Oklahoma through Saturday evening.
A heat advisory remains in effect until 10 PM CDT Tuesday.
Heat index: Temperatures reaching 100 to 109 with heat indices reaching 103 to 110 degrees each day with little overnight relief as low temperatures range from 75 to 83. The heat stress will be amplified by the persistent hot weather.
Impacts: the risk of heat related illness will continue through this week. Try to remain in an air conditioned environment and learn to recognize the signs of heat stress. Check on friends, family, and pets.
Precautionary/preparedness actions: Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to the early morning or late evening hours. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight 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.
