218 FXUS65 KFGZ 092304 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 404 PM MST Sun Nov 9 2025 .SYNOPSIS...Dry and mild weather will continue through much of next week. A colder and more unsettled pattern, with chances for rain and high elevations snow showers, arrives for Friday and into the weekend. && .DISCUSSION...A high amplitude ridge will gradually meander eastward over the next few days, peaking over our area on Monday or Tuesday. This ridge will send daytime temperatures to at least 5-10 degrees above normal for a few days. Localized areas may see daily records set as they peak to near 15 degrees above normal. Some deeper valley locations may not see as big of a response, due to inversions under the ridge. For the second half of the week, the pattern begins to break down as a strong and increasingly progressive trough forms over the eastern Pacific. Models have converged on a Friday/Saturday time frame, but still differ with regard to speed and timing. The more progressive solutions are colder, but drier. Conversely, the slower solutions are wetter, but warmer. This brings us to a higher confidence for cooler, wetter and windy weather, but a low confidence for potential snowfall. Right now, 6 hour NBM probabilities for more than one inch of snow have fallen below 20 percent, but are confined to a 24 hour period from Friday morning to Saturday morning. More details as we head into the start of the work week. Beyond this, we still may see a longer wave trough forming within the 8-14 day period, but models spread is impressive and lends to low confidence at this time. && .AVIATION...Monday 10/00Z through Tuesday 11/00Z...VFR conditions expected. Areas of FU/HZ possible from prescribed burns. Light north through east winds forecast through much of the period. However, N-NE winds 5-15 kts possible between 04Z-16Z along and south of the Mogollon Rim. OUTLOOK...Tuesday 11/00Z through Thursday 13/00Z...VFR conditions expected. Light and variable winds forecast for Tuesday, becoming W-SW on Wednesday 5-15 kts. && .FIRE WEATHER...Monday and Tuesday...Dry conditions with temperatures about 10 degrees above average. Winds light and variable or terrain driven. Minimum afternoon RH between 10-20%. Wednesday through Friday...Dry with above average temperatures through Thursday. On Friday, a pattern change arrives, temperatures dropping to 10 degrees below average. Precipitation also moves in, mainly in the form of rain, with snow falling above 8,000-8,500 ft. Winds SW-W at 10 mph or less on Wednesday, SW 10-20 mph on Thursday, SW 10-25 mph on Friday. Minimum RH 15-25% Wednesday and Thursday, rising to 30-35% deserts, 45-60% mountains. && .FGZ WATCHES/WARNINGS/ADVISORIES...None. && $$ PUBLIC...Peterson AVIATION...Konieczny FIRE WEATHER...Bernhart For Northern Arizona weather information visit weather.gov/flagstaff
