SOUTHWEST ARIZONA/SOUTHEAST CALIFORNIA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX ARIZONA
912 PM MST SAT SEP 13 2003

.SYNOPSIS...
CIRCULATION AROUND A HIGH PRESSURE SYSTEM JUST OFF THE SOUTHERN 
CALIFORNIA COAST...WILL CONTINUE TO PRODUCE A DRY NORTHWEST FLOW 
OVER SOUTHEAST CALIFORNIA...SOUTHWEST AND SOUTH-CENTRAL ARIZONA 
THROUGH THE MIDDLE OF NEXT WEEK. TEMPERATURES WILL REMAIN A FEW 
DEGREES ABOVE NORMAL...ALONG WITH MOSTLY CLEAR SKIES. 

.DISCUSSION...
RATHER STRONG UPPER RIDGE CONTINUES ALONG THE WEST COAST GIVING A 
NWLY FLOW TO AZ...WITH THE AIRMASS QUITE DRY AND STABLE. A BIT OF 
MID LEVEL MOISTURE SHOWED UP OVER NRN AZ ON THE FLG RAOB...ENOUGH 
FOR SOME CU OVER THE MOUNTAINS...BUT THAT WAS ABOUT IT. OTHERWISE AT 
9 PM SKIES OVER THE CWA WERE CLEAR. SURFACE DEWPOINTS STILL LOW... 
SORT OF A MIXED BAG RANGING FROM THE MID 30S TO MID 50S. AREA OF 
DISTURBED WEATHER SEEN WELL SOUTH OF SRN TIP OF BAJA...BETWEEN 10 
AND 20N. THIS NOT YET A TROPICAL SYSTEM...AND IS FORECAST BY PROGS  
TO MOVE WEST WITH TIME. EVEN IF IT DOES BECOME A TROPICAL DEPRESSION 
OR WORSE...TRACK SHOULD TAKE IT WELL OFF TO OUR S AND W...AND IT 
SHOULD NOT BE A PROBLEM AS THE WESTERLIES STAY RATHER STRONG OVER 
THE CONTINENTAL UNITED STATES. LATEST GUIDANCE KEEPS THE DRY WLY 
FLOW GOING INTO THE MIDDLE OF NEXT WEEK...AND NO WEATHER PROBLEMS 
ARE FORESEEN FOR THE NEXT 7 DAYS. NO UPDATES NEEDED.  11

.PSR...NONE
