PHOENIX — It's a nice start to the week across Arizona!

Valley temperatures warmed into the mid 70s on Monday and will do so again on Tuesday.

Overnights will drop into the upper 40s to mid 50s across the Valley all week.

Clouds will move in and breezes will start to pick up on Wednesday as a storm system approaches from the west.

This storm could also bring scattered rain and snow showers to our state on Thursday and Friday.

Here in the Valley, we could see anywhere from a trace to two-tenths of an inch of rain on Thursday with a slight chance of a few more isolated showers on Friday.

Temperatures will drop nearly 10 degrees too, putting Valley highs in the upper 60s Thursday afternoon.

Up north, the snow level will fall to around 6,000 feet. Flagstaff could pick up one to two inches of snow with this storm.

Another weak storm system will pass through the Four Corners on Saturday, keeping a slight chance of isolated showers in the forecast along the Mogollon Rim and across the Navajo Nation.

Our forecast here in the Valley will stay dry over the weekend as temperatures rebound into the low 80s by Sunday.
