KEY MESSAGES
* MONSOONAL MOISTURE WILL ATTEMPT TO PUSH INTO THE REGION LATER THIS
WEEK WITH THE BEST CHANCES FOR SHOWERS AND THUNDERSTORMS IN
NORTHWEST ARIZONA.
DISCUSSION
THROUGH SUNDAY.
RIDGING WILL NUDGE INTO THE REGION FROM THE EAST OVER THE NEXT FEW
DAYS BEFORE A SHORTWAVE SWINGS THROUGH CENTRAL CALIFORNIA ON
WEDNESDAY. THIS WILL RESULT IN SOUTHERLY FLOW ALOFT, WHICH WILL HELP
TO FUNNEL MOISTURE UP THE COLORADO RIVER VALLEY AND INTO NORTHWEST
ARIZONA. WHILE THIS MOISTURE INFLUX WILL BE MODEST, WITH
PRECIPITABLE WATER VALUES AROUND 100% TO 125% OF NORMAL, IT WILL BE
ENOUGH FOR A 15 TO 30% CHANCE OF AFTERNOON SHOWERS AND THUNDERSTORMS
ACROSS MOHAVE COUNTY DURING THE SECOND HALF OF THE WEEK. OUTSIDE OF
THIS POTENTIAL FOR SHOWERS AND THUNDERSTORMS ACROSS MOHAVE COUNTY
DURING THE SECOND HALF OF THE WEEK, WEATHER ACROSS THE REST OF THE
AREA WILL BE BENIGN WITH SEASONAL TEMPERATURES. DRY WESTERLY FLOW
WILL RETURN OVER THE WEEKEND, SCOURING MOISTURE FROM THE AREA.
AVIATION...FOR HARRY REID

CALIFORNIA...FOR THE 12Z FORECAST PACKAGE...LIGHT WINDS THIS
