NWS Flagstaff, AZ wrote its last area forecast discussion before the first event at Sep 9, 8:43 PM MST, 2 hours 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FLAGSTAFF AZ 843 PM MST MON SEP 9 2013 .SYNOPSIS...THE WET MONSOON WEATHER PATTERN WILL CONTINUE THROUGH WEDNESDAY WITH SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS. EXPECT SIGNIFICANTLY LOWER CHANCES FOR SHOWERS AND THUNDERSTORMS FROM THURSDAY ONWARD AS DRIER AIR MOVES IN FROM THE WEST. && .DISCUSSION...AN UPPER LEVEL LOW PRESSURE CENTER REMAINS NEAR THE CA/AZ BORDER THIS EVENING WITH A FEW DISTURBANCES ROTATING AROUND IT. ONE MOVING THROUGH NORTHEAST AZ CONTINUES TO BRING WIDESPREAD SHOWERS AS IT MOVES OFF TO THE NORTH. BEHIND IT...ISOLATED TO SCATTERED AND GENERALLY LIGHT SHOWER ACTIVITY IS NOTED ON RADAR. ANOTHER DISTURBANCE OVER SOUTHWEST AZ IS PRODUCING NUMEROUS THUNDERSTORMS. THIS SECOND DISTURBANCE WILL ROTATE UP THROUGH NORTHERN ARIZONA LATE TONIGHT AND TUESDAY...AND LOOKS TO BRING ADDITIONAL DESTABILIZATION AND LIFT TO THE REGION WHICH WILL RESULT IN WIDESPREAD SHOWER ACTIVITY AND EMBEDDED THUNDERSTORMS. OVERALL THE CURRENT FORECAST LOOKS GOOD FOR THE NEXT SEVERAL DAYS...BUT WILL MAKE SOME CHANGES TO ACCOUNT FOR SHORT TERM TRENDS DISCUSSED ABOVE FOR THE TONIGHT/TOMORROW MORNING FORECAST. && .PREV DISCUSSION/330 PM MST/...WATER VAPOR SATELLITE IMAGERY THIS AFTERNOON CONTINUES TO SHOW AN UPPER LEVEL LOW STRADDLING THE CALIFORNIA ARIZONA BORDER AND A SECOND LOW MOVING THROUGH SOUTHERN ARIZONA. DYNAMIC LIFT ON THE NORTHERN SIDE OF THIS SECOND LOW HELPED TO INCREASE SHOWER ACTIVITY ACROSS NORTH CENTRAL ARIZONA THIS AFTERNOON. THE DEEPEST LOW LEVEL MOISTURE PLUME WAS POSITIONED ACROSS CENTRAL ARIZONA TODAY. THIS DEEP MOISTURE PLUME WILL MOVE EASTWARD INTO NEW MEXICO TOMORROW...HOWEVER ENOUGH MOISTURE AS MEASURED BY PRECIPITABLE WATER (PW) WILL REMAIN TO PRODUCE GOOD CHANCES FOR RAIN SHOWERS. THE DECREASE IN EXTREME MOISTURE LEVELS ALONG WITH SLIGHTLY COOLER TEMPERATURES ALOFT WILL HELP TO DESTABILIZE THE AIR MASS AND PRODUCE HIGHER CHANCES FOR THUNDERSTORM ACTIVITY AS COMPARED TO TODAY. BY WAY OF COMPARISON...TODAYS BEST THUNDERSTORM ACTIVITY OCCURRED CLOSER TO THE DRIER AIR IN EXTREME EASTERN AND WESTERN ARIZONA...ALONG THE EDGES OF THE DEEPEST MOISTURE PLUME. MODELS CONTINUE TO CONSISTENTLY SHOW THIS AREA OF LOW PRESSURE SLOWLY MOVING NORTHWARD INTO UTAH BY WEDNESDAY AFTERNOON. THIS MEANS WE WILL CONTINUE TO SEE SCATTERED TO NUMEROUS RAIN SHOWERS AND THUNDERSTORMS TONIGHT AND TOMORROW WITH DEEP MOISTURE AND WEAK TO MODERATE UPPER LEVEL FORCING. WHILE THERE IS DECENT WIND SHEAR ALOFT FOR SOME ORGANIZED CONVECTION...THE THERMAL PROFILE ON THE MODEL SOUNDINGS ARE MOIST ADIABATIC INDICATING LOWER LEVELS OF INSTABILITY. THE BEST CHANCES FOR THUNDERSTORM ACTIVITY WILL BE ALONG THE EDGES OF THE DEEPEST MOISTURE PLUME TOMORROW. THE MAIN THREATS THROUGH TUESDAY WILL BE FROM LIGHTNING AND LOCALIZED FLASH FLOODING. ON WEDNESDAY...THE UPPER LEVEL LOW PRESSURE REGION WILL MOVE NORTH INTO UTAH AND DRIER AIR WILL BEGIN TO FILTER INTO NORTHERN ARIZONA FROM THE SOUTHWEST. ENOUGH MOISTURE AND INSTABILITY WILL LINGER FOR CONTINUED SHOWER AND STORM ACTIVITY. THURSDAY THROUGH SUNDAY...A SIGNIFICANT DOWN TURN IN THE CONVECTIVE ACTIVITY IS FORECAST AS WESTERLY FLOW ALOFT BRINGS DRIER PACIFIC AIR INTO ARIZONA. EXPECT A RETURN TO A LOW GRADE MONSOON WITH ISOLATED TO SCATTED SHOWERS AND STORMS THROUGH THE PERIOD. && .AVIATION....FOR THE 06Z PACKAGE...ISOLD SHRA/TSRA WILL AFFECT NORTHERN AZ UNTIL 12Z...WITH INCREASING SHRA/TSRA COVERAGE EXPECTED AFTER 12Z. BY 18Z...SHRA/TSRA WILL BECOME NUMEROUS. EXPECT A MIX OF VFR AND MVFR CEILINGS PREDOMINANT ACROSS NORTHERN AZ THROUGH THE NEXT 24 HOURS. HEAVIER SHOWERS AND THUNDERSTORMS WILL PRODUCE ISOLD IFR CEILINGS AND VISIBILITIES. AVIATION DISCUSSION NOT UPDATED FOR AMENDMENTS. && .FGZ WATCHES/WARNINGS/ADVISORIES...NONE. && PUBLIC.....DJO/BOHLIN AVIATION...DJO FOR NORTHERN ARIZONA WEATHER INFORMATION VISIT WEATHER.GOV/FLAGSTAFF
