Area Forecast Discussion National Weather Service Flagstaff AZ 1000 AM MST WED JUN 29 2016 .SYNOPSIS...Shower and thunderstorm activity will be on the increase over the next few days as a moist southerly flow develops across Arizona. Expect storms each day with the best potential for heavy rain arriving on Thursday and Friday. && .DISCUSSION...The PW off the KFGZ 12Z sounding is the same as yesterday morning (~0.75 inch). Stearing flow is southeast-northwest south of the south of the Mogollon Rim...and west to east-northeast north of the Rim. Storm motion today will be 10 to 15 MPH so local heavy rain is possible. No updates for today planned. && .PREV DISCUSSION /246 AM MST/...High pressure centered over the four corners region will gradually drift to a position over Texas during the next few days. For today...ample moisture is situated across northern Arizona. As daytime heating progresses and instability builds another round of thunderstorms is expected across northern Arizona. Storms will be most numerous along and south of a line extending from the Grand Canyon southeastward through Flagstaff and Show Low. Heavy rain will be possible with stronger storms with 1 to 2 inch downpours possible. As always gusty winds, small hail and cloud- to-ground lightning with storms. Pretty typical monsoon stuff. For Thursday through Saturday...Southerly flow will deliver deep monsoon moisture with widespread showers and thunderstorms. The deepest moisture will be located from the Mogollon Rim southward where storms will be the most numerous. At this time the best combination of flow, instability and moisture will be on Thursday and Friday roughly along and west of a Payson-Flagstaff-Grand Canyon line. Looks like the highest potential for heavy rain producing storms so far this monsoon. Stay tuned as details emerge. From Sunday onward...A drier and stabilizing westerly flow develops. Most areas across northern Arizona will see only a slight chance of showers and storms. The only exception will be the mountain areas along the Arizona/New Mexico border where lingering moisture will result in scattered storms. && .AVIATION...For the 18Z Package...Scattered to numerous TSRA expected to develop today with the focus of activity over the higher terrain of northern AZ. Locally heavy rain, small hail, and gusty winds possible with storms. Coverage of showers and thunderstorms will decrease overnight. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...An active monsoon weather pattern will continue through the week with scattered to numerous showers and thunderstorms each day. An increase in moisture will raise the threat for heavy rain by Thursday. Gusty outflow winds also possible near any shower or storms. Friday through Sunday...Active monsoon weather continues through Saturday with close to average temperatures. A downturn in thunderstorm activity is possible by Sunday or early next week. && .FGZ WATCHES/WARNINGS/ADVISORIES...NONE. && PUBLIC...MAS AVIATION...JJ FIRE WEATHER...MCS For Northern Arizona weather information visit weather.gov/flagstaff
