Area Forecast Discussion National Weather Service Flagstaff AZ 1005 AM MST Sun Jun 14 2026 .SYNOPSIS...Chances for showers and thunderstorms are expected through the weekend with slightly cooler temperatures. Warm temperatures and mostly dry conditions return for next week, with isolated chances for showers across the higher terrain each afternoon. && .DISCUSSION...Increased moisture will remain across the region through today bringing another round of scattered showers and thunderstorms. With skies having cleared out after yesterdays storms, activity should start to develop by late morning/early afternoon. PWATs are around 0.5-1.0" across much of the region so expect any storms that develop to be capable of producing heavy rainfall. Additionally, gusty outflow winds and lightning will continue to be hazards through this evening. Once the sun sets, we should see the activity wane across the forecast area. As we head into tonight, the moisture will start to diminish as dry air begins to push into the region. The dry air won't fully erode the moist conditions in place, displacing the moisture off to the south through the week. While much of the area will dry out this week, there will remain chances for some showers, mainly across the eastern Mogollon Rim and White Mountains. Coverage looks to be isolated at best but we will continue to appreciate any moisture that we can get. Another aspect of the coming week will be the increasing daytime temperatures as warmer air settles into the region with more typical afternoon breezes each day. && .AVIATION...Sunday 14/18Z through Monday 15/18Z...Mainly VFR conditions. SCT -SHRA/-TSRA between 18Z-03Z with brief MVFR and erratic winds gusting 30-40 kts. Daytime winds SW-W 10-15kts, light and variable or terrain driven overnight. OUTLOOK...Monday 15/18Z through Wednesday 17/18Z...Mainly VFR conditions. ISO-SCT -SHRA/-TSRA after 18Z on Monday, mainly south of a KGCN-KRQE line with brief MVFR and erratic winds 30-40 kts. ISO -SHRA/-TSRA on Tuesday, mainly south of a KPAN-KSJN line. Daytime winds SW-W winds 10-15 kts on Monday, becoming W-NW 10-20 kts on Tuesday. && .FIRE WEATHER...Today and Monday...Expect scattered showers and thunderstorms this afternoon and evening, then becoming isolated on Monday. Any storms that develop are capable of producing wetting rains and gusty, erratic winds that may reach 30 to 40 mph. Outside of storms, expect southwesterly winds at 10 to 15 mph. Tuesday through Thursday...Isolated showers and thunderstorms possible in the White Mountains each afternoon. Otherwise, expect warmer and mostly dry conditions to return. Westerly winds 10 to 20 mph on Tuesday, then becoming southwesterly 10 to 20 mph with gusts to 30 mph for Wednesday and Thursday. && .FGZ WATCHES/WARNINGS/ADVISORIES...None. && PUBLIC...Meola AVIATION...Bernhart FIRE WEATHER...Meola For Northern Arizona weather information visit weather.gov/flagstaff
