Phoenix set two heat records Tuesday for the hottest-ever temperature in October at 113 degrees and the latest day in the year above 110.
Ted Whittock is a meteorologist with the National Weather Service in Phoenix.
He says the heatwave is expected to continue due to a strong high pressure system over the western U.S. However, a low pressure system from the Pacific Northwest will likely bring some relief.
"All of our guidance is still showing that temperatures are going to remain above normal, but you know we're not going to see these high temperatures near record levels probably by the latter half of next week," he said.
Whittock said highs are expected to remain above normal at least through the first half of October.
