PHOENIX -- Temperatures were down a bit across much of Arizona Thursday. Still, we’re expecting temperatures to stay a bit above normal through Saturday, then a cooling trend will take over into next week.

Saturday, a weak weather disturbance will pass over Arizona, mainly in the morning hours. And while we could see a few light showers to the south and east of the Valley, we’re not expecting any rain for metro Phoenix. By Saturday afternoon, it will be mostly sunny.

Next week will feature some great fall weather. In metro Phoenix, we’re expected highs only in the 80s with overnight lows in the 50s and 60s.

NOAA issued the latest update on the El Nino for the upcoming winter and the basic information is that there won’t be an El Nino most likely. 

NOAA had been expecting a weak El Nino to begin showing itself but that isn’t happening. Sea surface temperatures in the Pacific are essentially neutral at this point, ENSO neutral is the technical term.

The impact on Arizona doesn’t really change our winter outlook. Previously we have been looking for a warmer than normal winter with equal chances at normal precipitation or less. That forecast wasn’t changed by NOAA Thursday.
