PHOENIX — Clouds are moving in as moisture streams in from the Pacific.

We may see a few random sprinkles here and there across our state, but overall the forecast is still looking dry.

Highs will be back in the 70s Wednesday and Thursday, but we're tracking cooler air and chances for rain and snow across Arizona as we head toward Christmas.

Several storm systems will be moving through the western U.S. later this week, over the weekend and early next week, keeping our weather pretty unsettled through the holiday.

We could see a few rain showers in the Valley starting Thursday with a chance for snow in the forecast up north.

Those rain and snow chances will ramp up quite a bit for Christmas Eve and Christmas Day, so it could end up being a White Christmas in parts of the Arizona high country.

Stay tuned to ABC15 for more specifics as we get closer!

In the meantime, we are tracking cooler temperatures just in time for Christmas, too.

Valley highs will drop into the 60s starting Friday and we'll stay there through Christmas weekend.
