AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
310 PM MST FRI AUG 24 2007

.SYNOPSIS...MOISTURE MOVING NORTHWARD ACROSS THE STATE WILL CAUSE A
GRADUAL INCREASE IN THE CHANCE FOR SHOWERS AND THUNDERSTORMS EACH
DAY THROUGH THE WEEKEND. DAYTIME TEMPERATURES WILL DECREASE TO NEAR
NORMAL LEVELS LATE IN THE WEEKEND INTO EARLY NEXT WEEK.

&&

.DISCUSSION...THUNDERSTORMS AND SHOWERS TODAY HAVE BEEN LIMITED TO
THE WHITE MOUNTAINS AND EASTERN GILA COUNTY. THE REST OF THE
FORECAST AREA HAS BEEN LIMITED TO STABLE CUMULUS CLOUDS. EXPECT
THESE THUNDERSTORMS TO CONTINUE OVER EAST CENTRAL ARIZONA UNTIL
AROUND MIDNIGHT WHEN THEY WILL DISSIPATE.

BY TONIGHT... FORECAST MODELS INDICATE THE POSSIBILITY FOR AN MCS TO
DEVELOP IN SOUTHERN ARIZONA ALONG THE MEXICO BORDER WHICH COULD PUSH
ADDITIONAL MOISTURE NORTHWARD FOR THE WEEKEND.

SATURDAY AND SUNDAY...THE RIDGE OF HIGH PRESSURE MOVES SLIGHTLY
NORTHEASTWARD ALLOWING A SOUTHEASTERLY FLOW PATTERN TO MOVE MOISTURE
UP INTO THE NORTHLAND. THIS PATTERN CHANGE WILL INCREASE OUR CHANCES
FOR SHOWERS AND THUNDERSTORMS EACH DAY WITH THE ACTIVITY PEAKING ON
SUNDAY.

MONDAY THROUGH THURSDAY...THE HIGH PRESSURE RIDGE WILL BUILD
WESTWARD OVER THE STATE. EXPECT WARMER TEMPERATURES AND LESS CHANCES
FOR SHOWERS AND THUNDERSTORMS AS A STABLE LAYER ALOFT WILL LIKELY
INHIBIT CONVECTION.

BOHLIN
&&

.AVIATION...FOR THE 00Z PACKAGE...MOISTURE INCREASING FROM THE SOUTH
WILL BRING SCT -SHRA/TSRA TO AREAS SOUTH OF THE RIM THROUGH 02Z-03Z.
EXPECT CIGS 5-7 KFT WITH THESE SHOWERS WITH ISOLD MVFR CONDITIONS.
ELSEWHERE...ISOLD TO SCT CU/TCU FIELDS WITH BASES 6-8 KFT AGL WILL
DISSIPATE AFTER 03Z. EXPECT SCT COVERAGE OF SHRA/TSRA BY 18Z-20Z ON
SATURDAY MOST ZONES...EXCEPT ISOLD IN THE FAR NORTHERN ZONES. CIGS
SATURDAY WILL RANGE FROM 5-7 KFT AGL WITH ISOLD MVFR CONDITIONS
THROUGH THE AFTERNOON. AVIATION DISCUSSION NOT UPDATED FOR
AMENDMENTS.
