MOST ACCURATE FORECAST: Big cool-down coming to Arizona this week

Posted
and last updated

PHOENIX — Temperatures are dropping across Arizona as another storm system approaches from the west.

Phoenix will fall into the upper 80s on Tuesday and Wednesday, after hitting the triple digits for the first time this year over the weekend.

Breezes will pick back up in the afternoon hours each day this week and it may even be windy at times on Wednesday with peak gusts topping 30 mph.

Those winds will bring in even cooler air by Thursday with Valley highs dropping into the upper 70s to low 80s. That will put us nearly 10 degrees below normal for this time of year.

As that storm system out west starts to move in, we could see scattered showers and thunderstorms across northern Arizona on Thursday and Friday.

At this point, it looks like the Valley will stay dry.

We are also still tracking Flood Warnings for parts of the Gila River through Tuesday evening as the flow increases due to water releases from upstream dams.
