Fire Weather Planning Forecast for Southwest and South-Central
Arizona and Southeast California
National Weather Service Phoenix AZ
258 AM MST Sun Jul 16 2017

.DISCUSSION...
Deep easterly flow around a high pressure system centered to our 
north will import copious amounts of moisture into the area today 
and into early next week. Showers and thunderstorms will become 
more widespread, especially across south-central Arizona, and 
locally heavy rain will be possible. Thunderstorms activity will
stay limited though over far southeast California with only
isolated coverage expected by Monday. High temperatures will 
trend downward, becoming well below seasonal normals by Monday. 
Minimum RH values will stay highly elevated, ranging mostly 
between 25 and 40 percent each day over the lower desert. Little
change in the wind pattern is expected as winds will remain rather
light, favoring the south over the western deserts, and the
southwest across south-central Arizona.

...Thunderstorms imply gusty winds...
