MUCH OF THE SHOWER AND THUNDERSTORM ACTIVITY WILL BE OVER THE
ARIZONA HIGH TERRAIN TODAY WHILE GUSTY STORM OUTFLOW WINDS WILL  BE
THE MAIN CONCERN TODAY FOR THE SOUTH-CENTRAL ARIZONA LOWER  DESERTS.
CHANCES FOR SHOWERS AND STORMS WILL QUICKLY DROP OFF  WEDNESDAY WITH
LITTLE IF ANY ACTIVITY EXPECTED THURSDAY AS HOTTER  AND DRIER
CONDITIONS SETTLE INTO THE REGION. HUMIDITIES WILL  REMAIN ELEVATED
TODAY WITH MINRHS OF 30-45% ACROSS THE EASTERN  DISTRICTS, WHILE THE
WESTERN DISTRICTS WILL DIP TO 20-25%. MINRHS  WILL THEN DIP TO
15-20% ACROSS ALL OF THE LOWER DESERTS STARTING  THURSDAY.

...THUNDERSTORMS IMPLY GUSTY WINDS...
