NORTHERN ARIZONA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
245 PM MST TUE SEP 02 2003

.SYNOPSIS...MOIST AND UNSTABLE AIR WILL REMAIN OVER NORTHERN ARIZONA
THROUGH THE WEEK. AS A RESULT...LOOK FOR SHOWERS AND THUNDERSTORMS
TO DEVELOP EACH DAY. WESTERLY FLOW WILL DEVELOP AND BRING DRYING
CONDITIONS BY EARLY NEXT WEEK.

.DISCUSSION...CENTER OF 500MB HIGH CURRENTLY LOCATED OVER NORTHERN
AZ AND NM WILL SHIFT TOWARDS THE WEST DURING THE DAY TOMORROW.
THOUGH PRECIPITABLE WATER VALUES HAVE BEEN STEADILY DROPPING IN
AREAS SOUTH OF FLAGSTAFF...THEY HAVE CONTINUED TO BE IN THE 0.80 TO
0.90 INCH RANGE FOR FLAGSTAFF DURING THE LAST 24 HOURS. EXPECT
SHOWERS AND THUNDERSTORMS TO CONTINUE INTO THE EVENING HOURS BUT TO
DIMINISH SIGNIFICANTLY IN INTENSITY AND COVERAGE OVERNIGHT AS
HEATING EXITS THE PICTURE. A SIMILAR LOW GRADE MONSOON FORECAST WILL
CONTINUE FOR WEDNESDAY AND THURSDAY. LATER IN THE WEEK...VERTICAL
WINDSHEAR IN THE ATMOSPHERE IS FORECAST TO STRENGTHEN. AS SUCH...THE
POTENTIAL FOR STRONG ORGANIZED STORMS SHOULD INCREASE FOR FRIDAY AND
SATURDAY. CONDITIONS ACROSS NORTHERN AZ SHOULD BEGIN TO DRY OUT
EARLY NEXT WEEK AS DRY WESTERLY FLOW ALOFT INTENSIFIES ACROSS THE
REGION.
