MOST ACCURATE FORECAST: Back-to-back storms headed to Arizona!

Posted
and last updated

PHOENIX — Temperatures are dropping as back-to-back storm systems move through Arizona.

Valley highs will fall into the low to mid-80s for the rest of the week.

Winds are picking up, too. It will be breezy every afternoon in the Valley through Saturday.

The first storm system moves in on Thursday, bringing a few showers and thunderstorms to the high country. Here in the Valley, there is a slight chance we could see a few isolated showers Thursday morning.

The second storm system dives in from the north on Friday, picking up winds even more and increasing chances for showers and thunderstorms across Arizona.

A Wind Advisory will be in effect for the Mazatzal Mountains, Pinal Mountains and Superstition Mountains from 2 p.m. Friday until midnight. Southwest winds between 20 to 30 mph with gusts up to 50 mph are expected.

Here in the Valley, gusts could hit 35 mph with the chance of a few showers Friday evening.

Chances for more showers and thunderstorms will be in the play Saturday afternoon across the higher terrain.

Although we aren't expecting much in the Valley, there is a slight chance one or two storms could move off of the mountains and into the far north or east Valley in the late afternoon or early evening.

This second storm system will clear out by Sunday and high pressure will return.

So, expect another big warm-up next week. Valley temperatures will climb back into the upper 90s by Tuesday and Wednesday.
