Fire Weather Planning Forecast for Southwest and South-Central
Arizona and Southeast California
National Weather Service Phoenix AZ
407 AM MST Fri Oct 20 2017

.DISCUSSION...
A Pacific weather system moving in will lead to cooler, near
normal temperatures for both Friday and Saturday but will also
bring breezy to windy conditions to our forecast area. While the
strongest winds will be focused over SE California on Friday,
minimum humidity will remain around 20%.  A drier, northwesterly
flow will develop on Saturday bringing breezy conditions to the
Lower Colorado River Valley. With this drier flow, minimum
humidities will drop into the single digits during the afternoon
while nighttime recoveries will be poor.

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