PHOENIX -- A storm system moving through Arizona Tuesday means an increased chance of showers and cooler temperatures for the Valley.
Afternoon highs will peak around 103 degrees under partly cloudy skies, with a 20 percent chance of showers and thunderstorms later in the day and into the evening hours.
Northern Arizona saw scattered storms throughout the morning hours Tuesday, and the National Weather Service issued a small stream flood advisory for the Schultz Fire burn area until 12:30 p.m. Heavy showers moving through the southern part of the area produced moderate flow in the washes near Hutchinson Acres and Pain Brush Road, according to NWS.
More rain is expected throughout the day, but storms will be more limited Wednesday and Thursday as drier air moves in from the west.
On Friday, a stronger monsoon flow returns, with an increased chance of storms in the Valley Friday night and Saturday.
A cool-down is also on the way. By the weekend, afternoon temperatures will only top out near about 99 degrees.
