Just when the triple-digit heat seemed behind us, a high-pressure system developing over Mexico should jack the mercury up to a record 101 degrees this weekend.
"By Thursday, we'll have a high of 95, Friday 100, and Saturday 101, so those are all very hot temperatures for this time of year," said Jaret Rogers, a meteorologist at the National Weather Service office in Phoenix.
Rogers said Sunday should cool down a few degrees."We have a forecast high of 97," he said. "Then another low-pressure system starts to affect the Western United States, and that should cool us off a little bit by Monday."
The high-pressure zone over Mexico and building toward the north should be over the Valley by Thursday and Friday.
"Basically, it's just going to dominate the weather pattern for the Southwestern United States," Rogers said.
Rogers added that the record high for Friday was 101 degrees, set back in 1991.
"The current forecast right now will hold us just below the record (on Friday)," he said.
However, Saturday's record is 100 degrees, which was set in 2003. The current forecast high of 101 degrees on Saturday would break that record.
