PHOENIX — Get ready for some big changes this weekend as our next storm system moves in.
This weekend storm could impact outdoor activities across the Valley, so Saturday and Sunday will be ABC15 Weather Action Days as a reminder to take action to stay safe in the storm.
Model estimates show the potential of a quarter to a half an inch of rain in some Valley neighborhoods this weekend, mainly Saturday night through Sunday morning.
Up north, the snow level looks to hover between 8,000 and 9,000 feet in elevation, so if we do see snow in Flagstaff it will be just be a few flakes mixed in with the rain.
Winds will pick up a bit, too. Peak gusts will approach 25 mph in the Valley and 35 mph in the high country this weekend. Of course, we could see stronger wind gusts associated with any thunderstorms that move through on Sunday.
The cooler air with this storm system will drop temperatures too.
Valley highs will fall into the upper 70s to low 80s on Saturday before plunging into the upper 60s to low 70s by Sunday.
Another storm system could move in on Tuesday and Wednesday with even colder air across Arizona.
Early morning lows in the Valley could dip into the upper 40s to low 50s by Wednesday morning.
That second storm could bring much lower snow levels, too.
So, stay tuned to ABC15 and abc15.com for updates as we get closer.
