Phoenix's Sunday heat breaks record at 89 degrees

Sunday afternoon brought record-breaking heat to the Phoenix area, with an 89-degree reading at Phoenix Sky Harbor International Airport, the National Weather Service said.

The previous record for the date was 88 degrees, meteorologist Mark O'Malley said. Phoenix tied the record at about 3 p.m. and broke it at 3:34 p.m., according to the Weather Service.

O'Malley attributed the Valley's recent heat wave to a high-pressure system hovering over the southwestern United States. The system should hang around until Monday before moving out and clearing the way for slightly cooler temperatures, he said.

Monday's high could hit 85 degrees, with a predicted low of 57 and a chance for some breeziness.

Tuesday will see slightly cooler temperatures, with a predicted high of 78 degrees and a low of 50.

Temperatures will likely hit 78 degrees Wednesday through Friday, with low temperatures ranging from 52 to 54 degrees.

Saturday's high temperature will reach 76 degrees, with a low of 53.

Average temperatures for this time of year are about 70 degrees, O'Malley said.

Next weekend could bring some rain, but it's still too early to predict how much.
