PHOENIX -- On the heels of record-tying heat Thursday, it just kept getting hotter in Phoenix. By around 3:30 p.m. Friday, the mercury had already risen to 111 degrees at Sky Harbor, dubbing June 7 the hottest day of the year.
The average high temperature for this date is 102. The heat prompted the National Weather Service to issue Excessive Heat Warnings for all southwest and south-central Arizona, including Maricopa and Pinal counties until 8 p.m. Friday. The hot temperatures also triggered an Ozone High Pollution Advisory Friday.
While the hotter than normal weather continues into the weekend and beyond, we will see a slight dip in temperatures starting Saturday afternoon. An area of low pressure off the coast of California will push a weak shortwave across Arizona Saturday afternoon. This push of moisture should keep temperatures rising past 109 on Saturday in Phoenix. By Sunday and into Monday, highs should be around 107 degrees. Skies will remain sunny.
Even though the heat will still be relatively dangerous to be out in for prolonged periods during the afternoon hours, an Excessive Heat Warning is not expected to be reissued because the temperatures don’t meet National Weather Service criteria for issuing such an alert.
As the shortwave makes it’s way across the Valley Saturday afternoon, we’ll see our winds kick up. We may have gusts of of to 25 miles per hour in the Valley through the night hours.
Early morning low temperatures across the Valley will remain in the low 80s and upper 70s through the weekend.
