PHOENIX — The monsoon season officially began on Wednesday and now the moisture will be moving in.

High pressure is right where we need it to be to pull in monsoon moisture from the south and a storm system approaching from the west will help, too.

Monsoon storm chances will increase across much of our state and we could see our first round of storms in the Valley on Friday or Saturday.

As that moisture moves in, temperatures will drop.

Look for highs in the lower 100s across the Valley through the weekend before temperatures heat up again next week.

We are also tracking high fire danger, too.

As winds pick up Friday and Saturday, parts of northwestern Arizona are under Wind Advisories and Red Flag Warnings. Peak gusts could approach 50 mph near Bullhead City.

We'll also have to watch out for lightning sparked wildfires as storm chances ramp up heading into the weekend.
