SOUTHWEST ARIZONA/SOUTHEAST CALIFORNIA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
923 PM MST SUN MAR 10 2002

.SYNOPSIS...
SEVERAL RATHER WEAK WEATHER DISTURBANCES WILL PASS BY TO THE NORTH 
OF ARIZONA THE NEXT FEW DAYS. EXCEPT FOR OCCASIONAL HIGH CLOUDS AND 
BREEZES...THESE DISTURBANCES WILL HAVE LITTLE EFFECT ON THE WEATHER 
OVER SOUTHEAST CALIFORNIA AND SOUTHWEST ARIZONA...WITH TEMPERATURES
WELL ABOVE NORMAL THROUGH WEDNESDAY. THEREAFTER...A COUPLE OF MUCH
STRONGER LOW PRESSURE DISTURBANCES ARE EXPECTED TO PUSH MUCH COOLER 
AIR...WINDY CONDITIONS AND CLOUDINESS THROUGH SOUTHEAST CALIFORNIA 
AND SOUTHWEST ARIZONA ON THURSDAY AND ON INTO NEXT WEEKEND. 

.DISCUSSION...
THE HIGH CLOUDS ASSOCIATED WITH A RATHER DRY SHORT-WAVE TROUGH THAT 
MOVED ACROSS THE REGION TODAY HAVE JUST ABOUT CLEARED THE FORECAST 
AREA TO THE EAST. THE FORECAST FOR TONIGHT LOOKS FINE...BUT I WILL 
TOUCH UP THE WORDING TO SHOW THE TREND INDICATED HAS INDEED BEEN 
COMPLETED. RIDGING AND WARMTH EXPECTED FOR THE NEXT FEW DAYS...AS 
WEAK DISTURBANCES MOVE OVER THE RIDGE TO OUR NORTH AND WE STAY HIGH 
AND DRY. A SERIES OF WHAT APPEARS TO BE 3 IMPULSES COME THROUGH THE 
REGION THU THRU SAT...OPENING THE DOOR FOR A STRONGER LOW PRESSURE 
SYSTEM TO DROP IN OVER THE AREA EARLY NEXT WEEK. OUR FORECAST LOOKS 
OK FOR NOW...WITH COOLING AND WIND THU THRU SAT...WITH THE GRADIENT 
RELAXING SUN...BEFORE THE MAIN SYSTEM MOVES DOWN FROM THE NW. LOOKS 
LIKE NO PRECIPITATION THRU SUN FOR NOW.  WILT
