Temperatures reach 110 degrees for record 25th straight day in Phoenix as summer swelter continues

Phoenix's record-breaking summer of heat continues as the city has recorded temperatures above 110 degrees for 25 consecutive days, extending a national record among large U.S. cities.

It's not necessarily cool at night, either. Another streak was extended on Monday when the low was recorded at 94 degrees in Phoenix, making it 14 days in a row with lows above 90, which is another national record among larger U.S. cities, according to Kenneth Kunkel, an atmospheric scientist at North Carolina State University.

Temperatures reached 116 degrees in Phoenix on Monday, which tied the daily record for July 24 and marked the 11th day with temperatures above 115 degrees this month in the area.

Phoenix's streak of days over 110 degrees, which now sits at 25, broke the previous record of 18 days which was set in 1974, as previously reported by The Arizona Republic, part of the USA TODAY Network.

Looking forward, the city may not see relief soon. An excessive heat warning, which has been in place in Phoenix since July 1, has been extended until Thursday.

This week, people residing in the Lower 48 can continue to expect hot temperatures this week, according to Monday's forecast from the National Weather Service.
