AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
900 AM MST SAT JUN 6 2015

.SYNOPSIS...A LOW PRESSURE SYSTEM NEAR SOUTHERN NEVADA WILL
INTERACT WITH MOISTURE ACROSS ARIZONA TO GENERATE SCATTERED
SHOWERS AND THUNDERSTORMS TODAY. SHOWERS AND STORMS WILL BE MOST
NUMEROUS ACROSS EASTERN ARIZONA. A DRIER AND WARMER AIR MASS IS
EXPECTED TO MOVE ACROSS THE AREA ON SUNDAY AND MONDAY BEFORE
UNSETTLED CONDITIONS DEVELOP AGAIN BY THE MIDDLE OF NEXT WEEK.

&&

.DISCUSSION...THE FORECAST LOOKS ON TRACK AT THIS TIME WITH A
PERSISTENT RAIN BAND OVER THE EASTERN THIRD OF ARIZONA. DRYING
STILL ON TRACK TO MOVE IN FROM THE WEST THIS AFTERNOON AND EVENING.

STEADY SHOWER ACTIVITY HAS PERSISTED ACROSS PORTIONS OF NORTHERN
ARIZONA MUCH OF THE MORNING...CURRENTLY MOST NUMEROUS FROM AROUND
PAYSON AND THE EASTERN MOGOLLON RIM TOWARDS THE FOUR CORNERS. EXPECT
THAT THE GREATEST STORM CHANCES INTO THIS AFTERNOON WILL REMAIN
ACROSS NORTHEASTERN ARIZONA. THE THREAT FOR LOCALLY SEVERE STORMS
CONTINUES...AND A WATCHFUL EYE ON THE RADAR IS OUR MAIN FOCUS TODAY.

AS THE UPPER LOW SHIFTS EASTWARD...SO WILL DRIER AIR AND A
LIKEWISE DECREASE IN SHOWER AND THUNDERSTORM ACTIVITY THROUGH
THE DAY. SUNDAY AND MONDAY WILL BE MOSTLY DRY WITH THE EXCEPTION
OF CONTINUED RAIN CHANCES IN THE WHITE MOUNTAINS.

ADDITIONAL MOISTURE FROM TROPICAL SYSTEM BLANCA MOVES INTO
SOUTHERN ARIZONA EARLY NEXT WEEK KEEPING LOW CHANCES FOR SHOWERS
OR STORMS IN PORTIONS OF THE FORECAST AREA. IT DOESN'T APPEAR TO
GET PULLED NORTH UNTIL POSSIBLY WEDNESDAY WHEN YET
ANOTHER PACIFIC LOW MOVES THROUGH THE REGION.

&&

.AVIATION...FOR THE 18Z PACKAGE...THE LOW PRESSURE TROUGH OVER
CALIFORNIA WILL WEAKEN AND SLOWLY MOVE EASTWARD TODAY. DRIER AIR
WILL ALSO MOVE INTO ARIZONA FROM THE WEST. EXPECT DECREASING
COVERAGE FOR SHOWERS AND THUNDERSTORMS IN NORTHWESTERN ARIZONA WITH
CONTINUED SCATTERED TO NUMEROUS COVERAGE IN THE NORTHEAST. PERIODS
OF MVFR AND IFR CONDITIONS SHOULD BE EXPECTED IN MODERATE TO HEAVY
SHOWERS WITH ERRATIC GUSTY WINDS NEAR STRONGER STORMS. CONVECTIVE
ACTIVITY WILL DIMINISH ACROSS THE STATE AROUND SUNSET. AVIATION
DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

.FIRE WEATHER...
A TROUGH OVER THE WESTERN USA WILL CONTINUE TO BRING TROPICAL
MOISTURE FROM THE SOUTH WITH SHOWERS AND THUNDERSTORMS MAINLY
EAST OF I-17 AND PAGE TODAY. SOME STORMS MAY PRODUCE STRONG WINDS.
DRIER AIR WILL FILTER INTO ARIZONA FROM THE WEST LATE TODAY AND
SUNDAY. ONLY ISOLATED STORMS ARE EXPECTED ON SUNDAY.

MONDAY THROUGH WEDNESDAY...TEMPERATURES WILL TREND WARMER AS DRIER
AIR MOVES INTO NORTHERN ARIZONA. WHILE ENOUGH MOISTURE WILL
LINGER OVER THE WHITE MOUNTAINS FOR SCATTERED SHOWERS AND STORMS
EACH DAY. DEW POINTS TREND HIGHER ON WEDNESDAY WITH HIGHER CHANCES
FOR SHOWERS AND STORMS.
