NWS Flagstaff, AZ wrote its last area forecast discussion before the first event at Jul 25, 9:18 AM MST, 3 hours 27 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FLAGSTAFF AZ 918 AM MST WED JUL 25 2007 .SYNOPSIS...A MOIST AND UNSTABLE AIR MASS WILL REMAIN ACROSS ARIZONA FOR THE NEXT SEVERAL DAYS. EXPECT SHOWERS AND THUNDERSTORMS TO DEVELOP EACH AFTERNOON...DIMINISHING DURING THE EVENING HOURS. CLOUDS AND PRECIPITATION WILL KEEP AFTERNOON HIGH TEMPERATURES SLIGHTLY BELOW NORMAL. && .DISCUSSION...MORNING SOUNDINGS INDICATE LITTLE CHANGE IN THE AIRMASS SINCE YESTERDAY. DEEP MOISTURE IS PRESENT WITH MID LEVEL FLOW OF 10-15 KT. PRECIPITABLE WATER VALUES REMAIN ABOVE AVERAGE FOR THIS TIME OF YEAR...120-130 PERCENT OF NORMAL. EXTENSIVE CLOUD COVER ACROSS CENTRAL COCONINO COUNTY SHOULD DELAY ONSET OF DEEP CONVECTION IN THAT AREA...BUT MOSTLY SUNNY SKIES OVER THE YAVAPAI CO MTNS...EASTERN MOGOLLON RIM AND MUCH OF APACHE AND NAVAJO COUNTIES THIS MORNING POINT TO AN EARLY START. THE MAIN THREAT WITH STORMS TODAY WILL BE LOCALLY HEAVY RAINFALL AS THE STORMS WILL BE EFFICIENT RAINFALL PRODUCERS. A FEW AREAS MAY SEE ENOUGH RAIN FOR SMALL STREAM FLOOD ADVISORIES LATER TODAY...BUT THE COVERAGE IS EXPECTED TO BE LOW ENOUGH THAT NO FLASH FLOOD WATCHES ARE NEEDED AT THIS TIME. A FEW STORMS MAY ALSO CONTAIN HAIL AROUND A HALF INCH IN DIAMETER. .PREVIOUS DISCUSSION...(230 AM MST WED JUL 25)...BY THURSDAY AND FRIDAY...A DEVELOPING SURGE IN THE GULF OF CALIFORNIA WILL ONLY SERVE TO INCREASE MOISTURE VALUES ACROSS THE STATE. WE WILL CONTINUE HIGH SCATTERED TO LIKELY POPS RIGHT ON THROUGH THE WEEKEND...IF NOT THROUGH THE REMAINDER OF THE SEVEN DAY PERIOD. IT WILL BE VERY DIFFICULT TO PINPOINT UP AND DOWN DAYS IN SUCH A MOISTURE RICH AIRMASS WITH HEAVY DEBRIS CLOUD EVERY NIGHT...SO WE WILL JUST STAY FAIRLY SIMILAR TO THE FORECASTS THAT HAVE BEEN ISSUED OVER THE LAST SEVERAL DAYS. PETERSON. && .AVIATION...FOR THE 18Z PACKAGE...SCATTERED THUNDERSTORMS WILL DEVELOP AFTER 18Z AND CONTINUE INTO THE EVENING HOURS WITH MVFR CONDITIONS ACCOMPANYING THE STRONGER STORMS. THE MAIN THREAT WITH STORMS WILL BE REDUCED VISIBILITY IN HEAVY RAIN. OTHERWISE...EXPECT CEILINGS OF 12 TO 17 KFT MSL ACROSS MUCH OF THE AREA OVER THE NEXT 24 HOURS. AVIATION DISCUSSION NOT UPDATED FOR AMENDMENTS. && .FGZ WATCHES/WARNINGS/ADVISORIES...NONE. && JJ / MCCOLLUM
