...DISCUSSION...
WELL DEFINED DEEP LAYER TROUGH EXTENDS FROM SOUTHERN CALIFORNIA 
AND NORTHERN BAJA CALIFORNIA SOUTHWEST ACROSS THE AREA TO THE 
ITCZ NEAR 135W. A PLUME OF UPPER LEVEL MOISTURE EMANATING FROM 
THE ITCZ IS ASSOCIATED WITH THE SOUTHERLY FLOW EAST OF THE 
TROUGH AXIS AND EXTENDS EAST OF A LINE FROM NEAR 32N105W TO 
20N118W TO 10N1135W. WEST OF THIS LINE THE ATMOSPHERE IS DRY AND 
CLOUD FREE IN THE MIDDLE AND UPPER LEVELS WITH PATCHY 
STRATOCUMULUS IN THE LOWER LEVELS. EVEN THE MOISTURE PLUME IS 
CLOUD FREE IN THE MIDDLE AND UPPER LEVELS. THE TROUGH IS 
FORECAST TO REMAIN IN PLACE AND STRENGTHEN THROUGH MID WEEK.

A MOSTLY UPPER LEVEL TROUGH IS OVER EASTERN MEXICO AND EXTENDS 
SOUTHWESTWARD OVER THE PACIFIC WITH A TROUGH AXIS FROM THE 
NORTHEAST PART OF THE YUCATAN PENINSULA TO NEAR 15N95W TO THE 
ITCZ NEAR 97W. THE TROUGH IS MOVING WEST ABOUT 15 KNOTS AND IS 
FORECAST TO ONLY WEAKEN SLIGHTLY IN THE NEXT SEVERAL DAYS. 
ASSOCIATED WITH THE TROUGH IS AN ACTIVE AREA OF CONVECTION WITH 
SCATTERED MODERATE WITH ISOLATED STRONG CONVECTION WITHIN THE 
AREA FROM 09N TO 15N FROM 91W TO 95W. A BROAD AREA OF MULTI

A BROAD AREA OF UPPER DIFFLUENCE.

REMAINDER OF THE MIDDLE AND UPPER LEVELS IS UNDER BROAD 
ANTICYCLONIC FLOW.
