The temperature has reached 100 degrees in Oklahoma City for the 51st day this year, topping a city record that dates back to 1980.
National Weather Service meteorologist Ty Judd says the mercury had reached 103 degrees by 4 p.m. Monday at Will Rogers World Airport, where the temperature for Oklahoma City is officially measured. The actual high temperature won't be available until Monday night.
Associate state climatologist Gary McManus says the 103-degree reading broke the record set in 1980 for 50 days of 100 degrees or hotter in Oklahoma City. McManus says the record was tied on Saturday, but the official high on Sunday only reached 99 degrees.
Judd says there will be slight chances for rain this week, but the triple-digit heat is expected to continue.
