PHOENIX — Highs stay about 10 degrees above normal and in the 70s Thursday, as clouds continue moving in as moisture streams in from the Pacific.

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 late 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.

Rainfall totals in the Valley expected to be anywhere from half an inch to an inch of rainfall through Christmas Day!

Snowfall in the high country is more uncertain. Snow levels will likely be higher compared to previous storms, meaning areas like Flagstaff may just get a wintry mix instead of all-out snow.

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.
