.SYNOPSIS...
A SOUTH TO SOUTHEAST FLOW ALOFT WILL BE IN PLACE OVER ARIZONA AND FAR
SOUTHEAST CALIFORNIA THROUGH MONDAY. THIS WILL PROVIDE SUFFICIENT
MOISTURE TO MAINTAIN THE THREAT OF THUNDERSTORMS FOR AT LEAST THE
NEXT COUPLE DAYS. HOWEVER...THE STORMS WILL TEND TO BE ISOLATED IN
NATURE AND CONFINED TO MOSTLY AFTERNOON AND EVENING HOURS.
MEANWHILE...AN UPPER LOW PRESSURE SYSTEM WILL DEVELOP NEAR THE
CALIFORNIA COAST BY THE MIDDLE OF NEXT WEEK. THIS SYSTEM WILL BEGIN A
GRADUAL PUSH OF DRIER AIR FROM WEST TO EAST REACHING SOUTH-CENTRAL
ARIZONA BY THURSDAY.

.DISCUSSION...
CONVECTION DEVELOPING OVER TWC AND FGZ CWAS...STARTING TO CREEP INTO
OUR CWA. ISOLATED STORMS OVER PINACATE MOUNTAINS OF SONORA BEGINNING
TO DRIFT INTO YUMA COUNTY AS WELL. BELIEVE THREAT OF THUNDERSTORMS
FOR OUR CWA WILL LAST THROUGH MONDAY NIGHT GIVEN AVAILABILITY OF
MOISTURE AND DISTURBANCES PROGGED TO MOVE THROUGH OR NEAR THE CWA.

STEERING FLOW. SUNDAY AFTERNOON AND EVENING COULD BE INTERESTING AS
PROGS ARE INDICATING SOME DYNAMICAL FORCING WILL BE AROUND...DUE TO
RIPPLES IN THE FLOW AS WELL AS DIFFLUENCE AND SPEED DIVERGENCE.
