Area Forecast Discussion
National Weather Service Flagstaff AZ
104 PM MST Tue Dec 9 2025

.SYNOPSIS...Expect warm days, chilly night and dry weather to
continue well into next week.

&&

.DISCUSSION...A dry northwest flow will remain entrenched across
the southwest United States into Saturday. Later on Saturday
through Monday a weak embedded weather disturbance will deliver
slightly cooler temperatures and variable high clouds, but that is
about it. Dry northwest flow will return for the remainder of next
week.

This afternoon through Saturday...A mild and dry air mass with
origins from over the central Pacific will result in unseasonably
warm daytime temperatures ranging from 10 to 20 degrees above
average. The dry air mass and mainly clear skies associated with
this pattern will result in strong radiational nocturnal cooling
with seasonably chilly overnight lows. Winds will primarily remain
light and variable at 5 to 10 mph through the period. The
exception, local drainage breezes of 10 to 20 mph south of the
Mogollon Rim due to the strong nocturnal cooling.

From Saturday into early next week...A weak and dry low pressure
system will result in slightly cooler daytime temperatures.
Otherwise, look for high clouds from Saturday afternoon into
Sunday associated with the core of this weak system. Light winds
will continue, southwest to west on Saturday and Sunday shifting
to more northwesterly on Sunday and Monday.

It appears our dry northwest flow pattern strengthens again later next
week.

&&

.AVIATION...Wednesday and Thursday...Dry and warm conditions
will continue with high temperatures reaching 10-20 degrees above
average. Light and variable daytime winds around 5 to 15 mph each
day. Minimum RH values between 20-35% each afternoon.

Friday through Sunday...Dry and warm conditions will continue this
weekend with high temperatures remaining 10-20 degrees above
average. Light and variable daytime winds around 5 to 15 mph each
day. Minimum RH values between 20-35% each afternoon.

&&

.FIRE WEATHER...Today and Wednesday...Dry and warm conditions will
continue. Light and variable daytime winds around 5 to 15 mph each
day. Minimum RH values between 15-35% each afternoon.

Thursday through Saturday...Dry and warm conditions will continue
through the end of the week. Light and variable daytime winds around
5 to 15 mph each day. Minimum RH values between 20-40% each
