SOUTHEAST ARIZONA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
205 PM MST SAT AUG 10 2002

.SYNOPSIS...MOISTURE REMAINS IN SOUTHEASTERN ARIZONA FOR SCATTERED
THUNDERSTORMS TODAY AND EARLY SUNDAY. HIGH PRESSURE EXTENDING FROM
WESTERN ARIZONA INTO THE EASTERN PACIFIC WILL BRING A DRIER AIR INTO
THE REGION LATE SUNDAY. THESE CHANGES WILL DECREASE THUNDERSTORM
ACTIVITY AND CAUSE TEMPERATURES TO GO ABOVE NORMAL EARLY NEXT WEEK.

.DISCUSSION...ACTIVITY SLOW TO START THIS AFTERNOON...HOWEVER
MOISTURE FIELDS ARE REMAINING IN COCHISE...GRAHAM...EASTERN PIMA AND
SANTA CRUZ COUNTIES. THE LOWER LEVEL GOES PRECIPITABLE WATER SHOWS
THAT WESTERN AND CENTRAL PIMA COUNTY HAVE DRIED OUT WHICH WILL
HINDER DEVELOPMENT THERE. SOUTHWEST NEW MEXICO IS ACTIVE TODAY AND
THESE STORMS ARE MOVING TOWARD THE ARIZONA BORDER.  EXPECT TO SEE
SOMETHING ASSOCIATED WITH THESE STORMS IN COCHISE COUNTY TONIGHT.

SINCE DRIER AIR IS GRADUALLY MOVING INTO THE SOUTHEAST PORTION OF
THE STATE FROM THE WEST AND NORTH...WILL CHANGE THE WORDING IN MOST
FORECAST ZONES FROM AN AREAL COVERAGE OF THUNDERSTORMS TO A
PROBABILITY CATEGORY. THIS CHANGE HELPS HIGHLIGHT AN INCREASED
UNCERTAINTY OF THUNDERSTORMS ACTUALLY OCCURRING. CERTAINLY NOT A
MAJOR CHANGE TO THE CURRENT FORECAST...BUT STILL NOTEWORTHY. HAVE
TWEAKED THE HIGH TEMPERATURES UP AND LOWS DOWN A BIT TO COINCIDE
WITH THIS DRIER AIR.

SEE NOTHING IN THE EXTENDED TO MAKE CHANGES AT THIS TIME.  THE HIGH
PRESSURE REMAINS NEAR CENTRAL AND SOUTHERN ARIZONA WHICH IS NOT THE
MOST FAVORED LOCATION FOR CONTINUING A MOIST ATMOSPHERE. MONDAYS
POPS ARE LOW. TUESDAY THROUGH SATURDAY WILL KEEP THE CHANCE WORDING
TO REFLECT THE UNCERTAINTY BEYOND SEVERAL DAYS THIS TIME OF YEAR.
GWS

.TWC...NONE.
