832 FXUS65 KFGZ 021732 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 1032 AM MST Tue Dec 2 2025 .SYNOPSIS...Cool and dry weather continues today. Another weak weather system brings a chance of light rain and snow showers from late tonight into Wednesday night, mainly from the Mogollon Rim north and east. Fair weather returns Thursday with a warming trend beginning on Friday and lasting through the weekend. && .DISCUSSION...A dry northwest flow will continue today, with temperatures a few degrees warmer than Monday. By late tonight through Wednesday, a shortwave will dive southward into the state bringing cooler temperatures and a chance of light snow showers (rain showers below 5000 ft). While most of the heavier precipitation is forecast to stay north and east of Arizona, there should still be enough moisture around for some showers. Low levels are starting out very dry, so this will limit amounts. NBM PoP forecasts seemed to be too low for Wednesday from the Mogollon Rim northeastward so we bumped these up quite a bit (still only 20-30%). Current forecasts are still calling for less than 1" of snow above about 6000 feet, and much of this is forecast to fall during daylight hours which limits road impacts. The better chance for any slick roads would be early morning Wednesday in northeast AZ, and again closer to sunset in areas where showers linger. The disturbance is forecast to exit the state quickly Wednesday evening, with precipitation chances ending by midnight. Thursday through the weekend - dry northwest flow is expected, with cold daytime temperatures Thursday, gradually warming to several degrees above normal by the weekend. Ridging will continue off the west coast keeping the storm track north of our region. && .AVIATION...Tuesday 02/18Z through Wednesday 03/18Z...Mainly VFR conditions, but areas of CIGS BKN7-11kft AGL slowly spreading south through the period.
