NWS Flagstaff, AZ wrote its last area forecast discussion before the first event at Jun 23, 9:33 AM MST, 4 hours 27 minutes earlier.
Area Forecast Discussion National Weather Service Flagstaff AZ 933 AM MST Thu Jun 23 2022 .SYNOPSIS...Showers and storms are expected across the majority of northern Arizona and through the next several days. This early monsoon pattern is forecast to stick around through the weekend and into the beginning of next week as well. Gusty winds, localized heavy rainfall, and potentially new fire starts due to lightning are the main concerns through the next 7 days. && .UPDATE...Clear skies across Arizona has allowed for instability to ramp up quickly this morning. A CU field is already developing along the higher terrain of the Bradshaw Mountains, Mogollon Rim, Black Mesa, and the Chuskas. The latest CAMs models indicate general thunderstorms will develop across northern Arizona today, with lightning, gusty winds, and very localized flooding being the primary hazards. The current forecast is on track with no updates planned at this time. && .PREV DISCUSSION /259 AM MST/...Majority of all shower and thunderstorm activity have subsided for the early morning hours today (Thursday). As the afternoon hours begin to roll around, the daytime heating along with the already available moisture will likely be enough to spin up a few showers today. We will continue to see the possibility of showers and thunderstorms throughout the next 7 days. Aside from any storm development over the next few days, mostly light winds and seasonable temperatures will persist. Our current synoptic pattern is Arizona is sitting between a closed low over California and a ridge over Texas. This combination is creating a southerly flow that is assisting with our moisture availability. This low is forecast to move north of our area by Friday, leaving room for the ridge over Texas to set- up over the Four Corners. This upcoming positioning is a favored location for ample monsoon moisture. Although many of us are probably enjoying the early start to the monsoon, we will continue to message the potential hazards that could be encountered during this active pattern. The primary hazards to be mindful of include...lightning, gusty outflow winds, and potential for flash flooding. Stay alert near burn scars and slot canyons. Just because rain is not falling directly on you, does not mean rain is not occurring upstream and could lead to flood/debris flowing toward you. Avoid flooded roadways and never drive into low-water crossings. Turn around, don't drown! Stay tuned to our social media pages (Twitter & Facebook) and weather forecasts prior to traveling during potentially hazardous conditions. && .AVIATION....For the 18z TAF package...Mainly VFR conditions expected through the TAF period except in and near showers and thunderstorms. Scattered thunderstorms will develop this afternoon and evening with gusty, erratic winds and locally heavy rain. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...Shower and thunderstorm chances will continue across the entire region Thursday and Friday. Winds outside of storm activity will be less than 15 mph. Lightning, gusty outflow winds, and flash flooding are possible with these storms. Saturday through Monday...A moderate monsoonal pattern will continue with daily chances for thunderstorms, light winds, and lower than average temperatures for this time of year. && .FGZ WATCHES/WARNINGS/ADVISORIES...NONE. && PUBLIC...TM/Swenson AVIATION...TM FIRE WEATHER...MCT For Northern Arizona weather information visit weather.gov/flagstaff
