PHOENIX -- A ridge of high pressure still in control of Arizona’s weather pattern will bring another round of triple-digit temperatures across the Valley headed into part two of the weekend.

Saturday afternoon, Phoenix Sky Harbor saw an afternoon high of 104 degrees. This was on the heels of Friday’s high of 104, which has so far been the hottest temperature Phoenix has seen this year.

Sunday morning, temperatures will dip to the low 70s across the Valley. In Phoenix, we’ll rebound to a high of 102 under mostly sunny to partly sunny skies.

A trough of low pressure slowly tracking east out of the Pacific Northwest will erode our ridge of high pressure, increase winds and drop temperatures over the next several days.

Red Flag warnings are in effect Sunday across northern Arizona for wind gusts of up to 40 mph, low relative humidity and dry fuels. This setup increases fire danger. Fire Weather Watches are in effect across the White Mountains and southeastern Arizona Monday and Tuesday.

In the Valley, we’re expecting wind gusts Monday and Tuesday to reach speeds as high as 25 mph.

By the start of the work week, high temperatures around the Valley will dip back to the mid and upper 90s.
