Area Forecast Discussion National Weather Service Flagstaff AZ 110 PM MST Tue Apr 1 2025 .SYNOPSIS...Windy conditions continue through early this evening, with an unsettled and colder pattern with chances for rain and snow through the rest of the week. Dry and warmer weather returns late in the weekend and into next week. && .DISCUSSION...The initial shortwave is pushing a cold front southward through the region this afternoon. The front was approaching a Prescott-Flagstaff-Window Rock line at 1230 PM. Along and ahead of the front, strong southwest winds are continuing, with gusts 40-55 mph. Behind the front, wind gusts drop off the 30 mph or less. There is also some scattered rain and snow shower activity along the front, though any accumulations should be spotty and minimal this afternoon. Wednesday - the next colder/deeper shortwave moves into Arizona from the northwest. This will bring a much higher chance of precipitation to the region, with snow levels dipping to 4500-5000 feet. There was little change with the afternoon forecast package regarding amounts, though PoPs were increased significantly. Still looking like a general 2-5 inch snowfall above about 6000 feet, though with the spring sun angle and warmer ground conditions we may not see that much on the ground at any given time. Won't issue any winter headlines at this time, but the most likely period of hazardous conditions along I-40/I-17 looks like mid afternoon Wednesday into the evening. Also looks like enough instability for a slight chance of thunderstorms Wednesday afternoon so that was included in the latest forecasts. Yet another shortwave moves southeast into the area for Thursday, continuing southward and closing off over southern Arizona by Friday. Additional showers are forecast each day, with snow levels gradually rising to around 5500 feet Thursday and 6000 feet Friday. Thursday's amounts are forecast to be 0.10" or less of precipitation and an inch or less of snow. Friday should be more convective, so while amounts are still light in general, some localized spots could see some higher amounts in isolated heavier showers. Some trailing showers continue Saturday especially in eastern Arizona. Late in the weekend into early next week - high pressure is forecast to build in with warmer temperatures and dry weather. && .AVIATION...Tuesday 01/18Z through Wednesday 02/18Z...Widespread VFR conditions expected today, with localized MVFR visibilities and ceilings mostly along and north of a KFLG-KRQE line from light rain/snow showers. Expect southwest winds 20-30 kts, gusting up to 50 kts through 02Z, with lighter winds returning overnight. Additional -SHRA/-SHSN could start along and south of a KGCN- KFLG-KSOW line after 12Z. Greater precipitation chances will occur after 18Z Wednesday. OUTLOOK...Wednesday 02/18Z through Friday 04/18Z...MVFR/IFR conditions likely in SHRA/SHSN between 18Z Wednesday and 06Z Thursday. Lingering showers possible Thursday afternoon, with greater chances after 18Z Friday. Expect southwest winds 10-20 kts on Wednesday, becoming lighter on Thursday. Gusty/erratic winds could occur near storm development. Overnight winds forecast to be light and variable. && .FIRE WEATHER...Wednesday and Thursday...Widespread rain and snow showers forecast for Wednesday, becoming more scattered across the higher terrain on Thursday. Winds will generally be out of the south- southwest 10-20 mph, but wind gusts near showers/storms could be gusty/erratic. Minimum RH values look to be 25-50% each afternoon. Friday through Sunday...A warming trend is expected over the weekend, with scattered showers continuing Friday and Saturday afternoon. Drier conditions look to return by Sunday, with limited precipitation over eastern AZ. Northerly winds will set up through the period, 5-15 mph, with potential for localized gusts near showers. && .FGZ WATCHES/WARNINGS/ADVISORIES...
