Area Forecast Discussion
National Weather Service Flagstaff AZ
107 PM MST Fri Jul 11 2025

.SYNOPSIS...Expect hot temperatures to continue into early next
week. Moisture will be sparse, with only isolated activity through
Sunday, primarily over the eastern portions of Arizona. A gradual
uptick in moisture may develop during the course of next week.

&&

.DISCUSSION...An overnight surge from the Gulf of California
brought much higher dew points to Arizona this morning, especially
over the lower deserts and south of the Mogollon Rim. This moisture
was on the shallow side and is now starting to mix out over our CWA,
especially at the higher elevations. Even with added boundary layer
moisture, the warm mid-levels continue to keep us capped.

The mid-level high is southwest of Arizona, which is not a good
location for moisture advection. We expect this hot and dry pattern
to continue, with minimal intrusions of moisture and near zero
chances for precipitation.

By next week, the high slowly starts to move north and eventually
eastward. This will cause for some easterly and northeasterly flow
to develop, potentially allowing for outflows to push moisture back
into the state. Later in the week, possibly an actual "monsoonal"
mid-level  high placement and an easterly wave may develop, possibly
bringing an uptick in activity.

This overall pattern can be hard to break, so keep in mind, as each
day goes by, fuels are drier and drier. Fire danger will become a
real concern in a short period of time without rainfall, be careful
out there.
