Tornadoes in Arizona? Big fall storm system on the way

Fall weather is finally settling in to parts of our state, but it may become a little too aggressive.

The powerful storm system is moving through Arizona, bringing a serious drop in temperatures along with wet and stormy weather.

The system is poised to hit Thursday evening and into Friday morning, bringing thunderstorms, chilly temperatures and strong gusty winds that may exceed 60 miles per hour.

The huge temperature drop is expected to hit on Friday and early Saturday.

Temperatures will be freezing above 6,500 feet early Saturday and Sunday mornings.

Read full forecast.

The storms that pop up could be capable of producing downburst winds in excess of 45 miles per hour, damaging hail and possibly even an isolated tornado.

Rainfall totals in the Valley should stay less than a quarter of an inch, but spots up north could receive as much as three quarters of an inch of rain with snow expected above 7,500 feet.

Accumulating snow may be seen above the 8,000 foot level at one to four inches by Friday morning on the Kaibab Plateau, San Francisco Peaks and White Mountains.
