Weather Outlook

Synopsis

Date & Time:  9/29/2016 11:51 AM MST
Forecaster:  Waters, S.

Clearing skies from south to north will put the kibosh on today’s light showers, giving us partly cloudy conditions and mild temperatures this afternoon and evening.  We’re not quite out of the woods as models are hinting at slight chances for isolated storms tomorrow afternoon.  Today’s high temperatures will reach the upper 80s in Wickenburg over to Carefree, with low 90s for Phoenix and Gila Bend.  Overnight lows will drop to the low 70s most areas except for the central City, which will see 75 or so.  A degree or two warming is slated for tomorrow with low 90s for the northern zones and mid-90s for the south.  Saturday looks to be a beautiful sunny day, again with highs in the low 90s north to the mid-90s in the lower southern zones.
