Fire Weather Planning Forecast for Southwest and South-Central
Arizona and Southeast California
National Weather Service Phoenix AZ
311 AM MST Fri Aug 18 2017

.DISCUSSION...
Very dry conditions will persist today before moisture begins
filtering back into our area tonight. This will bring a chance of
thunderstorms to the higher elevations on Saturday but the lower
deserts will remain dry. With the additional moisture, afternoon
minimum humidity will increase, albeit slightly, to near 15% for
the deserts while higher elevations will range between 20-25%.
Other than the usual upslope gustiness, relatively light winds
will prevail.

...Thunderstorms imply gusty winds...

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