508 FXUS65 KFGZ 212324 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 424 PM MST Fri Nov 21 2025 .SYNOPSIS...Cool conditions are expected today with a chance for light showers from around Flagstaff westward. Our next system will bring rain showers to the area late on Saturday into Sunday, with some high elevation snow possible above 7000 feet. Mild and dry conditions return for next week through Thanksgiving. && .DISCUSSION...A closed low is located west of the state this afternoon, with two circulation centers. One circulation is located west of Las Vegas, with some lift and plenty of moisture rotating up into western Arizona including Yavapai and western Coconino County. Some light rain showers have developed, with forecast soundings indicating snow levels as low as 7000 feet. This activity will continue into this evening before tapering off. The second circulation, centered around 400 miles west of San Diego, will become the dominant one and dive southeast toward northern Baja by Saturday afternoon. So much of Saturday looks like fair weather across northern Arizona, with mostly cloudy skies and a bit warmer temperatures. By Saturday evening, the low is forecast to start a northeastward trek across Arizona that will last into Sunday. The track has been shifting northward the past few model cycles, and is now right across central into northeast Arizona. This has caused snow levels to trend downward as well from Saturday evening into Sunday, as low as about 7000 feet. This of course makes it a tough call for rain vs snow at the elevation of Flagstaff and parts of I-40/I-17. For now, plan on some mostly light snow of up to an inch or two, though if things trend colder again these amounts may come up. If you`re planning travel around the region especially Saturday night and Sunday morning, be prepared for some snow above 7000 feet. The low is forecast to move rapidly northeast of the state by Sunday evening, with fair weather and warmer temperatures likely from Monday through next Friday including Thanksgiving. Heads up for the weekend after Thanksgiving - unsettled/colder weather may return so check back with us if you have travel plans. && .AVIATION...Saturday 22/00Z through Sunday 23/00Z...Mainly VFR.
