Area Forecast Discussion
National Weather Service Flagstaff AZ
346 AM MST Thu Dec 11 2025

.SYNOPSIS...High pressure will continue to bring dry and very
warm weather across the region into next week.

&&

.DISCUSSION...The dominant weather feature affecting the region
continues to be an anomalously strong ridge of high pressure
stretching across the eastern Pacific and the Intermountain West.
This ridge will gradually build across the region through the
rest of this week and into early next week, and then is expected
to gradually flatten into a more zonal flow by the middle of next
week. The result will be a continued dry pattern with and
abnormally warm temperatures and light winds for the next several
days. High temperatures will remain 15-20 degrees above average
through Saturday with a few record high temperatures possible.

A weak shortwave is forecast to undercut the ridge and pass
through Arizona on Sunday/Monday. We`ll see an increase in cloud
cover and a slight decrease in temperatures, with otherwise little
impact. A more zonal flow is forecast to develop by the middle of
next week which is expected to moderate temperatures and lead to
a slight increase in daytime winds.
