936 FXUS65 KFGZ 200908 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 208 AM MST Sat Jul 20 2024 .SYNOPSIS...Scattered showers and thunderstorms are expected each day through next week. Temperatures will remain a bit above average through the weekend, with light winds. && .DISCUSSION...Strong ridging continues over the western US, with the center slowly drifting westward through Monday. This places our region under a northerly flow regime aloft, not the typical monsoon orientation but enough moisture will remain in place for scattered thunderstorms each day. Moisture levels are highest along/south of the Mogollon Rim and this is where the better coverage of storms will be each day. Sunday afternoon and evening could be interesting south of the rim as northerly steering flow increases and higher CAPE values are also forecast. A few strong to severe storms and localized flooding is looking more likely Sunday evening in Yavapai/Gila counties. Outside of storms, it will stay hot through Monday though likely a bit short of warning criteria. Tuesday through Thursday - much of the guidance now forecasts the ridge to strengthen again and move back eastward toward Arizona. Although scattered storms are still forecast each day (especially along/south of the Mogollon Rim), the intensity of storms could be suppressed by the warmer mid level air in the ridge. We will also have to monitor the lower elevation areas for possible heat products if the ridge ends up as strong as some of the guidance shows. && .AVIATION...Saturday 20/06Z through Sunday 21/06Z...Outside of convective activity, VFR conditions and generally light winds. Saturday 18Z-03Z Sunday, expect SCT SHRA/TSRA and ISOLD +TSRA that may produce brief MVFR conditions and gusty/erratic winds.
