477 FXUS65 KFGZ 150853 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 153 AM MST Wed May 15 2024 .SYNOPSIS...A low pressure system will slide across southern Arizona today and tomorrow, bringing scattered showers/thunderstorms. A brief ridge will set-up Friday through the weekend, resulting in warmer/drier conditions. Unsettled weather looks to return by next week. && .DISCUSSION...A few isolated showers remain mostly north of I-40 tonight. Some of these spotty showers are producing gusty outflow winds, so a few localized areas may see brief elevated winds overnight. Otherwise, mostly quiet weather will persist through daybreak. Today and Thursday...A low pressure system will slide across southern Arizona today/tomorrow, allowing for increased precipitation chances across the High Country. Showers/thunderstorms will have the greatest coverage this afternoon compared to the isolated coverage seen the last couple of days. Although confidence is fairly low for widespread wetting rains, localized areas could see up to 0.25" of rainfall today. Elsewhere, 0.01-0.10" is likely from today`s showers. As the low continues to push eastward into New Mexico on Thursday, precipitation will dwindle and become more focused across the eastern Mogollon Rim/White Mountains. Friday through the Weekend...A ridge will build up for a few days across much of the Southwest, bringing afternoon temperatures 3-10 degrees above normal. Mostly sunny skies and warmer temperatures always seems to come with a price here in northern Arizona, and that price is breezy winds. We`ll start to see winds become elevated over the weekend associated with a forming low pressure system off the California Coast. As of now, expect mostly southwest winds 10-20 mph gusting 25-30 mph throughout the afternoon hours. Next Week...Unsettled weather will return to the forecast as the aforementioned low pushes inland. Model guidance is still not in agreement with timing/trajectory of this disturbance, so more details will follow as we get closer to next week. && .AVIATION...Wednesday 15/06Z through Thursday 16/06Z...Mainly VFR conditions are forecast. Brief periods of MVFR conditions are possible again on Wednesday from late morning through the afternoon. Be on the lookout for strong and gusty winds near heavier showers or thunderstorms. Otherwise, light and variable winds overnight will become southwest to west at 10-20 kts by Wednesday afternoon. OUTLOOK...Thursday 16/06Z through Saturday 18/06Z...Mainly VFR conditions are expected. Precipitation chances may linger through 12Z Thursday, but drier conditions look to return for the rest of Thursday and Friday. Afternoon winds will generally be out of the west at 10-20 kts each afternoon. && .FIRE WEATHER...Today and Thursday...Scattered showers/thunderstorms today will decrease to isolated on Thursday. Southwest to west winds at 5-15 mph today, becoming west to northwest on Thursday. Minimum relative humidity between 15-30% each afternoon. Friday through Sunday...Warmer and drier weather conditions are expected through the weekend. Southwest to west winds at 15-25 mph gusting near 30 mph each afternoon. Minimum relative humidity values will range between 10-20%. && .FGZ WATCHES/WARNINGS/ADVISORIES...None. && $$ PUBLIC...Konieczny AVIATION...McCollum FIRE WEATHER...MAS For Northern Arizona weather information visit weather.gov/flagstaff
