Arizona and Southeast California
National Weather Service Phoenix AZ
430 AM MST Fri Sep 22 2017

.DISCUSSION...
Upper level troughing and associated cool front will continue a
slow sweep through the districts, promoting additional
daytime/afternoon breeziness today. However, wind gusts will not
be as strong as those observed on Thursday. Cooler temperatures
will result, 8-10 degrees below normal and cooler still by the
weekend. Lowest daytime humidities will range from 12-20 percent
for the lower elevations and 20-30 percent for the
foothills/higher terrain locales today. Overnight recoveries will
range from fair to good.

Note...Additional Fire Weather Forecast information can be found
in the Area Forecast Discussion. See product PHXAFDPSR.
