082 FXUS65 KFGZ 200901 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 201 AM MST Thu Nov 20 2025 .SYNOPSIS...Rain and snow showers will continue today, primarily Flagstaff eastward. Cold and nearly dry conditions expected on Friday, outside of a few isolated showers possible across southwestern Yavapai County. Another disturbance will pass through the state this weekend, bringing additional showers to much of northern Arizona. Mild and dry conditions return for next week. && .DISCUSSION...The low pressure system bringing us all this moisture is currently centered across the western AZ border. Most of the current precipitation bands are east of I-17 and HWY 89, but isolated to scattered rain and snow showers elsewhere are possible through the night. This disturbance will slide across the state throughout the day, keeping precipitation chances mostly concentrated over eastern AZ. Friday...A minor lull in activity is anticipated as Arizona will find itself sandwiched between the exiting trough from this week, and another closed low quickly diving down the California Coast. We can`t completely rule out a few showers sneaking into southwestern Yavapai County on Friday, but overall it should be a fairly quiet (but cold) day. Saturday and Sunday...Within the last 24 hours, model guidance has shifted towards a slightly wetter pattern with this incoming low. Initially, guidance was projecting this disturbance to take a much more southerly track across the AZ/Mexico border. Now the low is being shown turning right up towards AZ and pushing towards the Four Corners. This trajectory will likely keep persistent showers in the forecast Saturday through Sunday. This does look to be a warmer system, where snow levels are forecast to range between 7500 and 8000 feet. Snow amounts do not look exciting, outside of the White Mountains above 8000` potentially seeing 3-6". A very light dusting could be seen across more populated areas (Flagstaff, Bellemont, Fort Valley). Next Week...Once this secondary low moves out of the region, above normal temperatures and dry conditions will become our main weather story. && .AVIATION...Thursday 20/06Z through Friday 21/06Z...MVFR/IFR conditions in SCT SHRA/SHSN through through 12-15Z, with ISO-SCT SHRA/SHSN and improving conditions thereafter. Winds VRB 5-10 kts, becoming W/SW after 18Z. OUTLOOK...Friday 21/06Z through Sunday 23/06Z...ISO-SCT SHRA/SHSN is expected each day, with periods of IFR/MVFR conditions expected. Otherwise, VFR conditions with E/SE winds 5-10 kts. Locally gusty NE winds downwind of the terrain overnight. && .FIRE WEATHER...Today through Friday...Look for scattered showers, becoming more isolated as the day progresses. The snow level will be around 6000-7000 feet today. On Friday another storm approaches but will track further south with any shower activity located south of the I-40 corridor. The Snow level will range from 6000-7500 feet on Friday. Winds west to southwest at 5-15 mph today, east to southeast at 5-10 mph Friday. Saturday through Monday...The chance for showers will continue through the weekend, primarily south of the I-40 corridor on Saturday then spreading area wide on Sunday. The snow level will range from 7000-8000 feet. Drying out Monday as the weekend storm system moves east. Winds east to southeast at 5-10 mph on Saturday, west to northwest at 5-10 mph on Sunday and Monday. && .FGZ WATCHES/WARNINGS/ADVISORIES...None. && $$ PUBLIC...Konieczny AVIATION...Humphreys FIRE WEATHER...McCollum For Northern Arizona weather information visit weather.gov/flagstaff
