.DISCUSSION...High temperatures will be 2-5 degrees above normal
through Sunday and then within a couple of degrees of normal next
week. 20-ft winds will generally be less than 15 mph through tonight
and then 15-20 mph on Saturday. A dry weather system will move to
our north on Sunday, resulting in windy southwest winds of 20-30 mph
and gusts to 40-45 mph across most of southeast Arizona. Breezy
afternoon and early evening conditions then persist much of next
week, especially to the east of Tucson. Min RHs values in the
valleys will be in the single digits to lower teens, with values
generally in the teens for the mountains.

On Sunday, the combination of strong and gusty southwest winds, low
relative humidity levels and a high fire danger rating will result
in near critical to critical fire weather conditions from the late
morning through early evening hours. A Fire Weather Watch has been
issued for all of southeast Arizona from 11 am to 7 pm MST Sunday.
