Fire Weather Planning Forecast for Southwest and South-Central
Arizona and Southeast California
National Weather Service Phoenix AZ
234 PM MST Wed Jul 9 2025

.DISCUSSION...
Regionally dry conditions and above normal temperatures will 
persist through the end of the week as lower deserts highs reach 
110-118 degrees today and tomorrow and then 105-110 Friday. MinRH
values will range from 10-20% through Friday day, while MaxRH 
values will be the lowest tonight at 20-40% before increasing up 
to 30-50% the following days. One exception will be across 
Imperial and southern Yuma Counties where gulf surges will result
in MaxRH values in excess of 50-60% starting tomorrow night. The 
overall wind pattern will follow the familiar diurnal trends today,
with some afternoon/early evening breeziness with 15-25 mph peak 
gusts. An uptick in the winds is expected tomorrow and Friday 
afternoons with 25-35 mph peak gusts. This may lead to locally 
elevated fire weather conditions tomorrow, while a low level
moisture increase Friday will keep MinRHs above critical level
(15%). Very low rain chances will exist through Friday, with 
activity focused mainly across the eastern and southeastern third 
of AZ, with CWR <10%.
