PHOENIX -- The monsoon began to reassert itself Friday night, and a chance for thunderstorms is continuing through the weekend.

An abundance of moisture is being pulled into the state from the south. That will help fuel the weekend storms.

The good news is that we’re seeing much cooler temperatures than the past couple of days. At noon Thursday, it was 110 degrees at Sky Harbor Airport. At noon Friday, the temperature was 102 degrees.

Dew points around the Valley are generally running in the 60s, which makes it feel pretty muggy out there, but they could also enhance any thunderstorms that may develop.

The high-pressure center that brought the region very hot temperatures the last few days will weaken and shift further off to the east. That will allow moisture that is now over Mexico to surge northward into the region.

Sufficient monsoonal moisture will then remain around the region to support afternoon and evening storm chances through at least the middle of the coming week.

Daytime temperatures will hold above seasonal normal but are expected to fall back from their near-record readings of the past couple of days.
