..DISCUSSION FROM PHXFWFPSR
ABUNDANT MOISTURE WITH A WEATHER SYSTEM RESIDING ACROSS WESTERN
PORTIONS OF THE REGION TODAY WILL HELP TO BRING FAIRLY WIDESPREAD
SHOWERS AND THUNDERSTORMS. BEST CHANCES WILL BE ACROSS SOUTHEAST
CALIFORNIA AND SOUTHWEST ARIZONA WHERE A FLOOD WATCH WILL BE IN
EFFECT FOR MUCH OF TODAY. RAIN CHANCES WILL CONTINUE INTO FRIDAY,
BUT MAINLY ACROSS THE ARIZONA HIGHER TERRAIN. HUMIDITIES WILL BE
ELEVATED OVER THE NEXT COUPLE OF DAYS WITH MINRHS MOSTLY BETWEEN
30-40% BEFORE GRADUALLY LOWERING CLOSER TO 20% BY SUNDAY. OUTSIDE
OF ANY STORMS, WINDS WILL REMAIN LIGHT OVER THE NEXT FEW DAYS WITH
DIRECTIONS MOSTLY FOLLOWING DIURNAL TRENDS.
..THUNDERSTORMS IMPLY GUSTY WINDS
