Area forecast discussion, Jul 1, 3:11 PM MST, 2 hours 55 minutes before
Area Forecast Discussion National Weather Service Flagstaff AZ 311 PM MST FRI JUL 1 2016 .SYNOPSIS...Expect active monsoon weather through Saturday with good coverage of showers and thunderstorms each day. Starting Sunday a drier westerly flow across Arizona will bring a downturn in activity heading into next week. && .DISCUSSION...Ongoing showers and thunderstorms over Coconino, Yavapai, and Gila counties will continue to drift east this evening before tapering off after dark. Only isolated to scattered activity is expected overnight. Moisture begins its slow exit beginning Saturday afternoon, though enough should linger for thunderstorms to form from the Grand Canyon southeast along the Mogollon Rim before dissipating again Saturday night. Starting Sunday...Westerly flow continues the drying trend, leaving most of northern Arizona with sunny skies and dry weather into the middle of next week. Enough moisture may linger for some showers and thunderstorms over the White Mountains. Long-range models indicate a brief return of moisture and thunderstorm chances for eastern portions of Arizona beginning Wednesday, as high pressure sets up over Texas once again. The moisture surge remains short-lived, however, as the models then sweep a low pressure trough through the region, drying out northern Arizona once again. This solution remains uncertain at this time, however, and will warrant watching as we enter the holiday weekend. && .AVIATION...For the 00Z Package...Scattered to numerous showers and thunderstorms will dimish after 03Z. With SCT to ISOLD -tsra overnight. Expect MVFR/IFR conditions and gusty winds with the stronger storms. Scattered thunderstorms will redevelop on Saturday by 17Z...mainly over the higher terrain. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...Scattered thunderstorms are expected to develop on Saturday, with only a few isolated storms on Sunday as drier air filters into the area. Storm motion will be from the west to the east. Monday through Wednesday...only a few isolated storm are expected through the period over the higher terrain...with generally fair weather as a dry westerly flow develops across the area. && .FGZ WATCHES/WARNINGS/ADVISORIES...NONE. && PUBLIC...TRC AVIATION...BAK FIRE WEATHER...BAK For Northern Arizona weather information visit weather.gov/flagstaff
