PHOENIX — Moisture continues to stream into Arizona ahead a storm system sitting off the coast of southern California.

That storm will finally track through Arizona on Wednesday, bringing more rain and snow chances to central, eastern and southern parts of our state.

The best bet for a few showers here in the Valley will be between 3 and 7 p.m. Wednesday. Rainfall amounts will be light with only a few hundredths of an inch possible.

Higher terrain spots above 8,000 feet in elevation along the eastern Mogollon Rim and into the White Mountains could see snow Wednesday night.

After that storm clears out on Thursday, high pressure will return and warm us up again.

Valley highs will warm up to the low 80s by Friday afternoon.

Then, we're tracking another storm that could bring more wind, rain and snow to Arizona late Saturday and Sunday. Overall, forecast models have been trending drier with this storm for Arizona, so we now only have a slight chance of a few spotty rain showers in our Valley forecast.

Breezes will pick up a bit Saturday and Sunday and cooler air with this storm will drop highs back into the low 70s on Sunday and Monday.
