.DISCUSSION...
Minimum relative humidities mainly 12-20 percent through Tuesday.
Breezy winds of 12-18 mph with gusts to 30 mph mainly through
Santa Cruz and southern Cochise counties, with lighter winds to
the north. Winds mainly on the lighter side to start the work
week, with potentially gusty southeasterly winds in the Gila
River Valley Wednesday. A push of moisture should begin to bring
up minimum relative humidities through the second half of the
week, however rain chances remain low through the remainder of the
work week.
