Fire Weather Planning Forecast for Southwest and South-Central
Arizona and Southeast California
National Weather Service Phoenix AZ
251 AM MST Wed Aug 23 2017

.DISCUSSION...
An upper level low west of Arizona will spread moisture north into
south central Arizona today, leading to isolated to scattered
afternoon and overnight showers and thunderstorms. Drier southwest
flow ahead of the low will push moisture eastward and largely
confine thunderstorms to the higher terrain east of Phoenix on
Thursday. High temperatures will stay near or slightly above
normal both days. Minimum RH values will mostly range between 15
and 25 percent over the deserts each day. Expect locally breezy
south to southwest flow this afternoon and evening, with slightly
less wind tomorrow.

...Thunderstorms imply gusty winds...

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