370 FXUS65 KFGZ 112030 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 130 PM MST Tue Nov 11 2025 .SYNOPSIS...Dry and mild weather will continue through Thursday. Weather turns breezy and cooler Friday, ahead of a storm system due Saturday and Sunday. This storm has changed in direction and rain and snow chances now arrive later. Expect colder temperatures and chances of rain and high elevation snow over the the weekend and into next week. && .DISCUSSION...The adage is that a cut off low is a weatherman`s woe. This is certainly turning out to be the case concerning the storm system we have been watching for the end of the week. While trends a few days ago were for a more progressive system, current trends are for this low to cut off from the westerlies much earlier than anticipated. The low then meanders off the California coast for several days, before ejecting northeast somewhere through the interior SW. This will start to change our forecast significantly, with a 24-36 delay in precipitation development and a reduction in potential snow amounts. The best QPF period now looks to be late Saturday through Sunday as the low ejects, even that could still change. We adapted the best we could, but now we will have to watch closely, as these cut off lows can really be stubborn. For early next week, it looks like a more active pattern as several lows potentially cut off over the SW, unsettled and cool looks solid for now. && .AVIATION...Tuesday 11/18Z through Wednesday 12/18Z...VFR conditions, no precipitation expected but some local haze/smoke from prescribed burns across the area. Winds light and variable at 10kts or less daytime, light and variable or terrain driven overnight. OUTLOOK...Wednesday 12/18Z through Friday 14/18Z...VFR conditions expected, only thing of note in the near term is some local haze/smoke from prescribed burns. However there is a slight chance of showers possible after 06Z Friday as a Pacific storm system begins to make its way in. Winds SW 5-15kts Wednesday, S 10-20kts Thursday. && .FIRE WEATHER...Wednesday and Thursday...Dry conditions with temperatures about 10 degrees above average. Winds S-SW 5-10 mph Wednesday, S-SW 10-15 mph Thursday. Minimum afternoon RH 15-25% on both days. Friday through Sunday...Unsettled conditions move into the region as early as Friday with the latest models showing a later arrival and longer duration of this next system. Precipitation chances last through the whole weekend with most of it likely falling as rain. Snow levels start around 9,000ft for Friday and Saturday, lowering to 7,500-8,000ft on Sunday. Winds SW-W 15-25 mph, gusting to 25 mph on Friday, SE-S 5-10 mph on Saturday, SW 10-15 mph Sunday. && .FGZ WATCHES/WARNINGS/ADVISORIES...None. && $$ PUBLIC...Peterson AVIATION...Bernhart FIRE WEATHER...Bernhart For Northern Arizona weather information visit weather.gov/flagstaff
