Phoenix weather: Changes coming
Updated today at 7:57 AM
PHOENIX -- Despite a cool start to the day, the Valley will see a pretty warm first afternoon of fall. Valley neighborhoods dipped to the upper 60s to mid 70s this morning under clear skies. Building high pressure will bring clear skies and abundant sunshine today with peak temperatures near 102 degrees.
Even warmer weather is likely tomorrow when highs rise to about 104 degrees, which is about 6 degrees above average for this time of year. Drier air moving in from the north will also cut storm chances across the state and bring lower humidity as well.
Warm and dry conditions continue Thursday before an approaching storm on Friday brings big changes. A low pressure system moving in from the northwest will bring a chance of Valley rain Friday through Sunday. The storm will also bring much cooler air into the state, with Valley highs forecast to peak in the low 90s both Saturday and Sunday with overnight lows in the 60s and 70s.
