NWS Flagstaff, AZ wrote its last area forecast discussion before the first event at May 27, 9:25 AM MST, 4 hours 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FLAGSTAFF 925 AM MST FRI MAY 27 2005 .SYNOPSIS...WEAKENING HIGH PRESSURE OVER THE DESERT SOUTHWEST ALONG WITH A SERIES OF APPROACHING PACIFIC LOW PRESSURE SYSTEMS WILL ALLOW MOIST SOUTHERLY FLOW TO DEVELOP THROUGH LATE MONDAY. THIS WILL BRING A COOLING TREND AND AN INCREASING CHANCE FOR SHOWERS. BY TUESDAY NIGHT...WEAK HIGH PRESSURE RIDGING LOOKS TO TAKE PLACE ALLOWING FOR WARMING AFTERNOON TEMPERATURES AND A RETURN TO DRY WEATHER FOR MOST OF THE NORTHLAND. && .DISCUSSION...A MOIST OUTFLOW BOUNDARY IS CONTINUING ACROSS THE STATE FROM THE SOUTH AND EAST THIS MORNING. SURFACE DEWPOINTS HAVE RISEN AT MANY STATIONS ACROSS NORTHERN ARIZONA WITH SOME LOCATIONS...INCLUDING THE COMMUNITY OF SHOW LOW...ALREADY BREAKING INTO THE 40S. GFS KEEPS FORECAST MOSTLY DRY TODAY...BUT WITH THIS ADDED INFLUX OF LOW-LEVEL MOISTURE FEEL THAT THE CURRENT FORECAST OF WIDELY SCATTERED SHOWERS AND THUNDERSTORMS SHOULD BE ON TRACK. CURRENT SYNOPTIC SETUP WITH WEAK LOW NEAR BAJA COAST WILL ALSO ADD FAVORABLE SOUTHERLY MOISTURE FETCH INTO SATURDAY. CONVECTION SHOULD INITIATE ACROSS THE HIGHER TERRAIN OF MOGOLLON RIM AND WHITE MOUNTAINS OVER THE NEXT COUPLE HOURS WITH THE LAST NAM RUN KEEPING NEGATIVE LIFTED INDEX VALUES ACROSS THE MOGOLLON RIM AND SOUTH THIS AFTERNOON. GFS SUGGESTS THAT AN ADDITIONAL PACIFIC STORM SYSTEM WILL DIP FROM THE PACIFIC NORTHWEST AND ACROSS THE STATE AROUND A MONDAY-TUESDAY TIME FRAME. THIS WOULD PROLONG THE CHANCE OF PRECIPITATION THROUGH AT LEAST LATE TUESDAY AND ADD SOME POTENTIAL FOR SOME RATHER BREEZY DAYS ON MONDAY AND EARLY TUESDAY. FORECAST THEN APPEARS TO RETURN TO MODERATE HIGH PRESSURE RIDGING FOR THE REMAINDER OF THE 7-DAY FORECAST PERIOD WITH WARMING AFTERNOON TEMPS AND DAILY AFTERNOON CONVECTION TAKING ANOTHER SABBATICAL. WILL RE-EVALUATE EXTENDED FORECAST WITH AFTERNOON PACKAGE BUT CURRENT FORECAST IS IN LINE WITH UPDATES ANTICIPATED AT THIS TIME. && .FGZ WATCHES/WARNINGS/ADVISORIES...NONE. && KD
