MOST ACCURATE FORECAST: Storm bringing rain, snow and cooler air to Arizona

Posted
and last updated

PHOENIX — Clouds are moving in ahead of our next storm.

That storm will move across Arizona on Thursday, bringing scattered showers and a big dose of cool air.

Here in the Valley, we could see anywhere from a trace to two-tenths of an inch of rain on Thursday with a slight chance of a few more showers on Friday. Isolated thunderstorms will be possible, too.

Temperatures will drop nearly 10 degrees too, putting Valley highs in the upper 60s Thursday afternoon.

Up north, the snow level will fall to around 6,000 feet. Flagstaff could pick up one to two inches of snow with this storm on Thursday, but will see more rain than snow on Friday.

Another weak storm system will pass through the Four Corners on Saturday, keeping a slight chance of isolated showers in the forecast along the Mogollon Rim and across the Navajo Nation.

Our forecast here in the Valley will stay dry over the weekend as temperatures rebound into the low 80s by Sunday.
