Saturday’s temperature had triggered an excessive heat warning across Arizona as lows were expected to range between 80F and 86F
On Saturday afternoon, the National Weather Service announced that the temperature at Phoenix Sky Harbor international airport reached 110F, making it the 54th day this year with temperatures of at least 110F.
Saturday’s temperature breaks the previous record of 53 days that was set in 2020. From 1991 to 2020, the average consecutive days of 110F or above is 21 days, the NWS said.
An excessive heat warning has been issued for south central and south-west Arizona until 8pm on Sunday as weekend highs are expected to range between 108F and 114F. Meanwhile, lows are expected to range between 80F to 86F.
That’s an approximation. Celsius is no longer defined in terms of water boiling and freezing, and they are no longer exactly 0 and 100.
The modern definition of Celsius is based on absolute zero and the triple point of water. And those are also the basis for the modern definition of Fahrenheit.
