Big cool-down this weekend across Arizona!

and last updated

PHOENIX — High pressure has been cranking up the heat across Arizona, but we are just a couple of days away from a major cool-down.

After topping out in the low 100s Friday, the Valley will drop into the upper 80s to low 90s over the weekend!

Before that happens, winds will crank up as a storm system passes to our north.

Wind Advisories are in effect from 11 a.m. until 7 p.m. across much of the Arizona high country today. South to southwest winds at 20 to 30 mph with gusts up to 45 mph are expected in places like Flagstaff, Williams, Munds Park, the Grand Canyon, Snowflake, Winslow, Holbrook and Tuba City.

Here in the Valley, gusts could approach 30 mph Friday afternoon.

Those winds will usher in cooler air, dropping temperatures 8 to 12 degrees across Arizona by Saturday.

Temperatures will start to climb again early next week with Valley highs in the mid 90s on Monday, Tuesday and Wednesday.

By Thursday, rain chances will be back in the forecast as we track remnant tropical moisture moving in from a storm soon to be named Priscilla.
