PHOENIX — Back-to-back storm systems are moving through Arizona dropping temperatures, cranking up winds and bringing chances for rain and snow to our state.

Temperatures have dropped nearly 20 degrees since the start of the week, putting Valley highs in the low to mid 80s.

Winds are picking up across Arizona and they will get even stronger on Friday.

A Wind Advisory is in effect for the Mazatzal Mountains, Pinal Mountains and Superstition Mountains from noon Friday until midnight. Southwest winds between 20 to 30 mph with gusts up to 45 mph are expected.

Another Wind Advisory is in effect across the Mogollon Rim and along I-40 in northeastern Arizona from 9 a.m. to 7 p.m. Friday. Gusts there could hit 45 mph, too.

Here in the Valley, expect gusty winds Friday afternoon and evening topping out near 35 mph.

Showers and thunderstorms will also impact areas north and east of the Valley Friday evening. There's a slight chance one or two of those storms could move down off of the higher terrain into the Valley.

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

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 before potentially hitting the triple digits again next Thursday.
