Fire Weather Planning Forecast for Southwest and South-Central
Arizona and Southeast California
National Weather Service Phoenix AZ
354 AM MST Sat Sep 21 2024

.DISCUSSION...
Some isolated shower and storm activity may persist into the
morning hours across the eastern districts, but will result in
only brief rain and low CWR`s (generally less than 10%).
Otherwise, a drier and cooler airmass encompassing the region
will result in below normal temperatures through today. More
traditional diurnal winds patterns will encompass the region over
the next several days. MinRH`s will hover around 15-30% region-
wide through today, with some slight drying across the region
starting tomorrow, with MinRH`s more in the 10-20% range by the
beginning of next week and extending into the middle of next week.
Overnight RH recoveries will be fair to good across the region
through tomorrow morning, before degrading to generally fair to
poor in spots going through the middle of next week. Warming
temperatures to above normal are expected to develop tomorrow and
persist through most of next week.

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