Phoenix weather: cooling off this weekPosted: Updated:
PHOENIX -- Cool and dry air will remain over the Valley for the start of the week, with high temperatures in many lower desert locations struggling to reach 70 degrees. Tuesday will be another chilly morning with near-freezing temperatures expected across the higher elevations of southern Gila County. Most lows in the Valley Tuesday morning will be in the upper-30s to mid-40s.
A gradual warming trend is expected through the middle of the week when high temperature readings will once again approach normal. Late week will feature a series of weak disturbances move through south central Arizona with a slight chance of showers over the higher terrain. Right now, it doesn’t look like the Valley will have much in the way of rain chances.
The dry northwesterly flow aloft will continue for the next few days along with the super dry air mass statewide, which moved in from Idaho and Utah. On Tuesday considerable mid and high clouds will slowly spread across the state with conditions becoming mostly cloudy by late in the day.
Clouds are in advance of an approaching weak Pacific weather system, which is forecast to move into the western states Tuesday night and Wednesday. Current forecasts show mid-week highs will be in the 70s.
