PHOENIX (CBS5) -

High clouds streamed into Arizona Tuesday afternoon, just the beginning of a significant weather change for the entire state.

A cut-off low pressure system is starting to take shape off the California coast. Being offshore, it will be able to tap into a rich source of moist air, bringing us the best chance of widespread rain we've seen in at least the past two months around here.

The best chance of rain begins on Friday.

Due to the cut-off nature of this system (it is not pushed along by the jet stream storm track) it will linger around the southwest for a few days.

So look for a continued chance of showers on Saturday, then as the colder center of this system moves back over the state on Sunday, additional showers will pop up throughout the day.

Snow levels will be fairly high with this setup: Between 7,000 to 8,000 feet, perhaps lowering just a little by the end of the weekend.
