.DISCUSSION...A dry weather system moving to our north today will
result in windy southwest winds of 15-30 mph and gusts between 35-45
mph through the early evening hours tonight. High temperatures will
briefly cool to below normal levels on Monday behind this system.
Temperatures then remain near to slightly above normal through
Thursday before warming up to 4-7 degrees above normal by next
weekend. Breezy afternoon and early evening winds will persist much
of this 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.

A Red Flag Warning remains in effect for all of southeast Arizona
until 7 pm MST this evening. The combination of strong and gusty
southwest winds, low relative humidity levels and a high fire danger
rating will result in critical fire weather conditions through the
early evening hours tonight.
