BIG cool down this week

PHOENIX — We are also tracking a major cool-down next week as a storm system moves in from the northwest.

Winds will pick up, temperatures will drop and we could even see a few rain and snow showers across Arizona on Monday and Tuesday.

Wind gusts could top 25 mph in the Valley and 40 mph up north early next week, and those winds will usher in some much cooler air.

We have a Wind Advisory going into effect for Northern Arizona Monday at 11 a.m. through Tuesday at 9 a.m.

Communities in Mohave, Coconino, Apache, Navajo could see sustained winds of 20-30 mph, with gusts up to 45 mph.

Gusty winds could blow around unsecured objects, so bring lawn furniture and anything not tied down inside. Tree limbs could be blown down and cause power outages.

Expect temperatures across the state to drop around 20 degrees by Tuesday, bringing the Valley back into the mid-70s.
We could see a few spotty showers in the Valley late Monday and Tuesday with a few hundredths of an inch of rain in some neighborhoods.
Up north, the snow level will start out around 10,000 feet on Monday but drop to 6,500 feet by Tuesday morning. That could bring a light dusting of snow into the Flagstaff area. Right now, less than one inch of snow is expected.
It does appear that it will clear out in time for Halloween, keeping the forecast dry all across Arizona for trick-or-treating.
Phoenix will top out in the low 80s on Halloween with trick-or-treating temperatures in the mid 70s.
