PHOENIX -- A ridge of high pressure responsible for unseasonably warm temperatures in Arizona will break down as a Pacific system tracks into the region this weekend.

Valley highs are expected to reach the low 90s for one more day before the temperature tumble begins.

Look for a high of around 92 in Phoenix on Friday. Trick-or-treaters will hit the streets with temperatures in the 80s after sunset.

On Saturday, Phoenix’s daytime high will drop to around 80 degrees with the mid-70s on tap for Sunday. Low temperatures will dip into the 50s by Sunday night.

As the system moves eastbound across the state, winds will be breezy at times across the Valley. Wind gusts of 30 to 50 mph are possible Saturday and Sunday in the High Country.

This system is also expected to bring rain to the Mountains this weekend. The Valley should remain dry with periods of cloud cover. Sunday morning, a dusting of snow is possible below 7,000 feet as cold air interacts with trailing moisture.

The cooler than average temperatures are expected to continue for at least the first half of next week. High country rain chances will linger through at least Monday.
