.DISCUSSION...High temperatures will be 2-5 degrees above normal
through Sunday and then within a couple of degrees of normal next
week. Today, 20-ft winds will generally be 15-20 mph with min RHs
values of single digits to teens in the valleys and in the teens
for the mountains. By Sunday, dry weather system will move to our
north, 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.
