SOUTHWEST ARIZONA/SOUTHEAST CALIFORNIA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
245 PM MST SAT JUL 14 2001

.SYNOPSIS...
A LARGE PACIFIC LOW PRESSURE SYSTEM WILL BECOME STATIONARY ALONG
THE WEST COAST THROUGH THE MIDDLE OF NEXT WEEK. AS A RESULT...MORE
STABLE AND DRIER SOUTHWESTERLY FLOW WILL DEVELOP OVER SOUTHEAST
CALIFORNIA AND SOUTHWEST ARIZONA...TO PROVIDE A BREAK IN THE MONSOON.
SLIGHTLY COOLER TEMPERATURES ARE ALSO FORECAST FOR THE REGION...WITH
HIGH TEMPERATURES FALLING A FEW DEGREES BELOW NORMAL. A RETURN OF
MONSOON MOISTURE IS POSSIBLE BY THE END OF NEXT WEEK.

.DISCUSSION...
UPPER FORCING FROM THE PASSING SHORTWAVE THIS MORNING HAS MOSTLY
ENDED THE THREATS FOR CONVECTION ON THE SOUTHWEST AND SOUTH CENTRAL
AZ DESERTS...EXCEPT FOR ONE LITTLE NUISANCE STORM ANCHORED OVER THE
MARICOPA MOUNTAINS JUST EAST OF GILA BEND...AND A FEW STORMS OVER
OUR MOUNTAINOUS ZONE 24. AS THE LARGE PACIFIC TROF MOVES ONTO THE
WEST COAST...SOUTHWESTERLY WINDS ALOFT WILL CONTINUE TO INCREASE
SUBSTANTIALLY. OUR CWA WILL SIT UNDER THE ANTI-CYCLONIC SHEAR/STABLE
SIDE OF THE 300/250 MB JET MAX FORECAST TO BECOME NEARLY STATIONARY
FROM SOUTHERN CA TO NORTHWEST ARIZONA. ALSO...LOW LEVEL MOISTURE
WILL BEGIN TO THIN EACH DAY AS 700 MB WINDS BECOME SUSTAINED 15-20
KNOTS FROM THE SOUTHWEST SUNDAY THROUGH MONDAY...LIGHTER TUESDAY.
ONE CAVEAT THOUGH.

PLOT DATA...AS WELL AS VAPOR IMAGERY SHOWED A VERY LARGE INVERTED
TROF MOVING ONTO THE EAST CENTRAL MEXICAN COAST. THIS FEATURE IS
FORECAST TO MOVE INTO THE PACIFIC SUNDAY AFTERNOON...THEN MOVE UP
THE BAJA COAST SUNDAY NIGHT AND MONDAY TO RENEW LARGE CONVECTIVE
THREATS OVER NORTHWEST MEXICO...JUST SOUTH OF SOUTHEAST AZ.  THIS
MEXICAN CONVECTION WILL LIKELY EXTEND INTO FAR SOUTHEAST AZ LATE
SUNDAY AND MONDAY NIGHT...WITH POSSIBLE OUTFLOWS PUSHING MOISTURE
BACK INTO SOUTHERN AZ...AND POSSIBLY VIA A SURGE UP THE COLORADO
RIVER VALLEY AND SOUTHWEST AZ. THATS THE CAVEAT... PARTICULARLY
MONDAY EVENING.

FOR NOW WE WILL GO WITH A DRY AND MOSTLY SUNNY FORECAST SUNDAY
THROUGH MONDAY ACROSS THE ENTIRE CWA. THIS DUE TO THINNING LOW LEVEL
MOISTURE AND UNFAVORABLE WINDS ALOFT. THE EXTENDED PERIOD WILL BE
DRY AS WELL...OR UNTIL WE CAN ASCERTAIN POSSIBLE EFFECTS ON OUR CWA
FROM THE MEXICAN INVERTED TROF. VASQUEZ
