PHOENIX -- Desert dwellers are basking in unseasonably cool temperatures left behind from a day of drizzle in the Valley of the Sun.

Early Tuesday morning, the Valley was greeted with light showers that continued through the late afternoon hours.

As of 4 p.m, Queen Creek was the big winner for rain, with a reported total of around a third of an inch. Other Valley locations including Scottsdale, Tempe and Fountain Hills were just shy of a tenth of an inch of rainfall.

According to the National Weather Service, the official high at Sky Harbor was 92, reached at 12:41 a.m. The low was 76 degrees, recorded at 11:51 a.m. During the afternoon hours, most communities saw temperatures in the low to mid 80s. The seasonal average for Phoenix is 105.

A trough that brought the rain is moving north out of Arizona Tuesday night. Behind it, drier air will move in from the southwest ahead of a low pressure system that’s tracking into California from the west. This low will push monsoon moisture to the east and allow skies to clear overnight.

The expected low temperatures in the Valley Wednesday morning should dip down to the mid 70s.

Afternoon high temperatures should rebound to the low 100s under sunny skies. Gradual warming will continue through the week as conditions remain dry.

Isolated storms are expected to redevelop across the higher terrain of northern and eastern Arizona both Wednesday and Thursday.
