Triple-digit temperatures have firm grip on ValleyPosted: Updated:
PHOENIX -- The Valley of the Sun saw slight relief Monday on the heels of the hottest weekend of the year. Sky Harbor hit 105 just before 4 p.m. That high temperature was four degrees cooler than Sunday’s.
A subtropical ridge over northern Mexico was suppressed a bit Monday by a weak trough pushed a cooling piece of energy across Arizona, albeit temperatures still averaged a good five degrees warmer than normal.
We’ll see little change with this set up across the Valley heading into Tuesday and Wednesday, with highs near 105. By Thursday, an area of high pressure moves in from the northwest, kicking up temperatures at or just shy of 110 degrees. Expect a repeat performance of that heat for Friday.
Weekend temperatures look like they have the potential to dip a couple of degrees.
Overnight lows for the next seven days should be in the upper 70s across the Valley.
The Arizona Department of Environmental Quality expects ozone levels to be unhealthy for sensitive groups both Thursday and Friday thanks to diminishing winds that will allow pollutants to settle at the surface. Those with respiratory problems, young children and the elderly should limit their outdoor exposure during this time.
No rain is expected across the state over at least the next seven days. Expect abundant sunshine.
