and last updated

PHOENIX — Rain and snow are moving into Arizona overnight as a storm system tracks through.

Here in the Valley, there's a slight chance we could see a few spotty showers through Wednesday morning, but rainfall totals will be light (less than a tenth of an inch.)

Up north, snow will fall above 4,500 feet in elevation. Snowfall accumulations will likely be less than an inch between 4,500 feet and 5,500 feet in elevation.

For areas above 5,500 feet, there's a chance for one to four inches of snowfall Wednesday through early Thursday morning.

We're also tracking a big cool-down with this storm. Temperatures will drop 10 to 20 degrees across our state.

Valley highs will fall into the low 60s Wednesday with early morning lows in the 40s.

Temperatures start to rebound across our state Thursday and Friday as we dry out again.

Here in Phoenix, look for highs in the low 70s Friday and mid to upper 70s over the weekend.
