Area Forecast Discussion
National Weather Service Flagstaff AZ
1002 AM MST Tue Dec 9 2025

.SYNOPSIS...Expect dry and warm conditions through this week.

&&

.DISCUSSION...The forecast remains unchanged, we are in a quiescent
period of weather through at least early next week. A consistent
strong ridge over the eastern Pacific is keeping northern AZ under
a dry northwest flow. This feature is expected to slowly push more
inland over the next few days, bringing light winds and warming
temperatures. Daytime highs look to peak 10-20 degrees above normal
Thursday-Friday. By the weekend, ensemble guidance is in agreement
that heights will fall slightly as the ridge flattens. Temperatures
will cool but still sit above normal into next week. A few passing
disturbances through the period will bring occasional periods of
high clouds, no but precipitation is expected. The only other
thing of note will be efficient radiational cooling leading to
breezy nighttime terrain winds, particularly along/south of the
Mogollon Rim.
