Cool tonight across the Valley with slightly cooler weather on the way

PHOENIX — High pressure has given us a warm start to the weekend but temperaute will begin to drop slighlty tomorrow as clouds build in across Arizona.

Temperatures have been well above average across the Valley with high near the 80s. The average last 80-degree day is November 24, but last year we stayed in the 80s until after December 17.

The latest 80-degree day on record is December 30, 1980.

Overnight temperatures will still be chilly as the Valley drops into the upper 40s to mid 50s for the next few days.

As our next storm system approaches, clouds will move in and temperatures will drop to the mid 70s by Sunday.

We’ll also see slight chances for a few spotty rain and snow showers across Arizona as that storm passes by next week, mostly in the high country.

Parts of northern Arizona could pick up a tenth to a quarter of an inch of rain, mainly Tuesday night and Wednesday.

The snow level will gradually lower to around 6,000 feet on Wednesday across the high country with a light dusting of snow possible in Flagstaff.

This storm will clear out in time for Thanksgiving with temperatures dropping into the mid 70s here in Phoenix.
