PHOENIX -- An unseasonably strong storm system is moving through Arizona Thursday night. With it, we're seeing isolated showers and thunderstorms. We've also seen some flash flooding and have had reports of small hail. In northern Arizona, there is a slight chance for severe thunderstorms overnight.

In the Valley, we had some decent, fairly quick showers Thursday morning. Scottsdale Airport and Ahwatukee got .02 inch of rain. Nothing at Sky Harbor International Airport. We expect the overnight hours into Friday to be the most “active” for metro Phoenix, i.e., the best chances for scattered showers and perhaps a thunderstorm.

So while there's a pretty decent chance you'll see rain around your Valley neighborhood through early Friday morning, don't expect much in the way of heavy rain. Perhaps a few locations will get more than 1/10” of rain. In northeastern Arizona, especially in the Rim Country, precipitation estimates are still pretty good, in the range of 1/4 inch to 1/2 inch of rain at many locations.

On the backside of the storm, much cooler temperatures are anticipated. Friday afternoon highs for Phoenix will only be in the mid-70s, down 20 degrees from a couple of days ago. And some of the mountain regions on Saturday morning will experience lows in the 20s! That will represent the first real cold temperatures of the season.
