Fire Weather Planning Forecast for Southwest and South-Central
Arizona and Southeast California
National Weather Service Phoenix AZ
245 AM MST Sat Jul 20 2024

.DISCUSSION...
Thunderstorm coverage will generally expand from higher terrain
areas of eastern districts into lower elevations through the
weekend. While some beneficial wetting rainfall will be possible,
strong gusty outflow winds will be more prevalent impacting any
ongoing fires or new starts. Aside from thunderstorms, winds
across the region should maintain afternoon upslope flow with
gusts 20 to 25 mph. Minimum humidity levels will mostly range from
15-25% following a wide range of overnight recovery from 20% in
western districts to 75% in the far east.

...Thunderstorms imply gusty winds...
