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

THAT, CONDITIONS WILL BE DRY THROUGH THE MIDDLE OF NEXT WEEK WITH
TEMPERATURES WITHIN A FEW DEGREES OF SEASONAL NORMALS.
