OKLAHOMA CITY, Okla. — A persistent heat dome has parked over Oklahoma, pushing daytime highs into the upper 90s and producing dangerous heat index values between 100°F and 110°F over the next several days before expected relief later in the week.

• Check on elderly neighbors and those with medical needs

“These heat index values are dangerous; people should take precautions and limit outdoor exposure,” the National Weather Service warned.

Community response & infrastructure

Local governments are opening cooling centers and alerting first responders to increased heat-related calls. Utility companies may also issue conservation requests during peak electric demand.
