SYSTEM. HIGHS NEAR 80S ACROSS THE LOWER DESERTS TODAY WILL FALL INTO
THE LOW TO MID 70S TUESDAY. HUMIDITY WILL BE RELATIVELY LOW; MINIMUM
RH VALUES TODAY OVER THE DESERTS WILL MOSTLY RANGE BETWEEN 15 AND
20 PERCENT, AND WILL RISE A FEW PERCENT TOMORROW. LOOK FOR BREEZY
SOUTHWEST TO WEST WINDS THIS AFTERNOON ESPECIALLY ACROSS WESTERN
IMPERIAL COUNTY. WINDS WILL TURN MORE TO THE NORTH TUESDAY AND STAY
BREEZY ACROSS DESERTS TO  THE WEST OF PHOENIX.
