524 FXUS65 KFGZ 071126 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 426 AM MST Thu Nov 7 2024 .SYNOPSIS...An area of low pressure will continue to bring snow to parts of eastern Arizona through tonight, with the highest amounts across the mountains. Some lighter snow is expected as far west as Flagstaff before shifting to the east through the day. Warmer and drier weather returns on Friday through the weekend with another trough expected early next week. && .DISCUSSION...A slow moving low is currently located across north- eastern Arizona early this morning, The low will slowly drop slightly southward through this morning before starting to push towards the east this afternoon. Isolated to scattered snow showers have pushed as far west as Flagstaff but as the low makes a shift to the south and then east, the precipitation should start to follow suit. Highest snow amounts look largely confined to the higher elevations of the San Francisco Peaks and the Chuska Mountains where 2-6" of snow is expected. By late afternoon, the low will be headed into New Mexico. The shower activity will also push east with the areas along the New Mexico/Arizona state line keeping the best chances as we head into the evening hours. Drier air will start to move in behind the low so while temperatures will remain fairly cold, we should start to see showers end pretty quickly from west to east. Another thing to keep an eye on will be the winds. The pressure gradient really tightens up as the trough pushes to the east and we will see strong northerly winds around 15-25 mph with gusts up to 30-40 mph through at least early this afternoon before winds drop off this evening. Behind the departing low, things start to clear out and we should see a slight warming trend for Friday through the weekend with dry conditions expected. Any lingering stronger winds or showers on Friday will be confined to right along the AZ/NM state line. A weak trough may approach the region from the west late in the weekend, but it looks like it lacks moisture and not much oomph as it move through. Likely some increase in cloud cover and some increase in the winds but otherwise not expecting much impact as it crosses the area. The next trough to move through the region will start to push down from the Pacific Northwest late Monday and Tuesday. This trough looks move into the area by late Tuesday into Wednesday. Again, this trough will bring an increase in winds and clouds, along with colder temperatures, but the moisture component isn`t looking all that promising as the trough crosses to our north. Something to keep an eye on as a slightly deeper trough may access a bit more moisture and bring a few more snow showers to the area. Stay tuned for updates in the coming days! && .AVIATION...Thursday 07/12Z through Friday 08/12Z...ISO-SCT SHSN expected through 03Z, mainly north and east of KPGA-KFLG-KJTC line.
