.DISCUSSION...THE WIND MACHINE CRANKS UP AGAIN TODAY...BUT NOT A
STRONG AS FRIDAY...WITH AREAS EAST OF TUCSON HAVING THE STRONGEST
GUSTS....WHERE A WIND ADVISORY WILL BE POSTED (GRAHAM...COCHISE AND

INCREASING ACROSS PART OF SE AZ WITH A VERY SLIGHT CHANCE OF LIGHT

THE MOUNTAINS AS A SYSTEM MOVES THROUGH THE GREAT BASIN. GRADIENT
