745 FXUS65 KFGZ 012015 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 115 PM MST Mon Dec 1 2025 .SYNOPSIS...Cool and dry weather continues Tuesday. Another weak weather system brings a chance of light rain and snow showers from Wednesday into early Thursday but only for northeastern and eastern parts of Arizona. Fair weather returns Thursday afternoon with a warming trend beginning on Friday and lasting through the weekend. && .DISCUSSION...Trough that brought the clouds and a few showers to far northeast Arizona is well east of the area this afternoon. In the wake of this trough, we should see some of the coldest if not the coldest morning lows of the season as winds die down and the dry air moving in allows for some good radiational cooling overnight. Continued ridging over the eastern Pacific places us in a relatively consistent northwesterly flow aloft which will keep us dry Tuesday with temperatures near seasonal averages. A shortwave riding down this northwesterly flow moves through the area Wednesday into Thursday. However models have been coming into pretty good agreement on placement of this wave, and each successive model run has been pushing the wave further northeast with a drier solution. As things stand now, the scenario looks similar to the wave that just passed with the only places with any type of precipitation expected will be the White Mountain region and the Chuskas. Impacts should be relatively low with expected QPF less than a tenth of an inch of rain or snow amounts less than an inch. Temperatures retreat a little in the wake of this system, with highs about 5 degrees above average. After Thursday, the ridge over the Pacific will nudge to the east a little over the weekend bringing a warming trend with temperatures at seasonal averages Friday and about 5 degrees above average Saturday and Sunday. Another shortwave rides down the east side of the ridge Sunday night into Monday but at this time this one looks even farther north than the Wed/Thur one and the only consequence will be temperatures cooling down a few degrees. && .AVIATION...Monday 01/18Z through Tuesday 02/18Z...VFR conditions.
