.DISCUSSION...VERTICAL CLOUD DEVELOPMENT HAS BEEN LIMITED TODAY AND 
CONFINED TO MAINLY MOHAVE COUNTY. A COUPLE OF ISOLATED STORMS WERE 
NOTED EARLIER OVER NORTHERN MOHAVE COUNTY NEAR THE COCONINO COUNTY 
BORDER. THERE REMAINS A SLIGHT CHANCE OF STORMS THIS AFTERNOON OVER 
MOHAVE COUNTY BUT THERE IS EVIDENCE OF DRY AIR ENCROACHMENT FROM THE 
WEST, AT LEAST AT THE SURFACE WHERE DEWPOINTS HAVE DROPPED FROM NEAR 
60 DEGREES EARLIER TODAY ALONG THE COLORADO RIVER VALLEY TO CURRENT 
VALUES IN THE MID TO UPPER 40S. 

STRONG HIGH PRESSURE OFF THE SOUTHWEST COAST WILL KEEP THE TROPICAL 
SYSTEM CURRENTLY KNOWN AS TROPICAL STORM MARIE WELL OUT TO SEA OVER 
THE NEXT COUPLE OF DAYS AS IT WEAKENS AND DISSIPATES. HOWEVER, SOME 
OF THE HIGH LEVEL MOISTURE FROM THE SYSTEM COULD MAKE IT INTO THE 
AREA FRIDAY AND SATURDAY AS A PACIFIC TROUGH APPROACHES THE COAST 
AND DIRECTS THE MOISTURE EASTWARD. THE TROUGH WILL PASS THROUGH THE 
NORTHERN GREAT BASIN AND NORTHERN ROCKIES OVER THE WEEKEND 
POTENTIALLY BRINGING LOCALLY GUSTY WINDS TO THE AREA. OTHER THAN 
THAT, CONDITIONS WILL BE DRY THROUGH THE MIDDLE OF NEXT WEEK WITH 
TEMPERATURES WITHIN A FEW DEGREES OF SEASONAL NORMALS.

.SPOTTER INFORMATION STATEMENT...SPOTTER ACTIVATION IS NOT EXPECTED
