SOUTHWEST FLOW WITH FAST MOVING DISTURBANCES AND PACIFIC MOISTURE
WILL BE COMBINING WITH LOW LEVEL MOISTURE...TO PRODUCE WIDESPREAD
SHOWERS AND ISOLATED THUNDERSTORMS...WHICH WILL BE DEVELOPING AND
RIDING OVER THE SAME GENERAL LOCATIONS. THE DEEP SUPPLY OF MOISTURE
AVAILABLE WILL ALLOW FOR BURSTS OF LOCALLY HEAVY RAINFALL. HAVE

RAIN. AS THE UPPER TROUGH OVER THE WESTERN U.S. CONTINUES TO
AMPLIFY SOUTHWEST THE PACIFIC MOISTURE CONNECTION WILL BE CUT OFF AND
