Area Forecast Discussion
National Weather Service Flagstaff AZ
340 AM MST Wed Dec 17 2025

.SYNOPSIS...Dry conditions and unseasonably warm temperatures are
expected through the weekend and into next week.

&&

.DISCUSSION...Above normal hghts of varying amplitude will persist
through the forecast period. A few stronger s/wvs to our north will
flatten out the ridge pattern from time to time, resulting in some
high cloud cover and more pronounced southwesterly breezes, but
temperatures will remain the same.

Northeast drainage flow over higher terrain will decrease over the
coming days, as southwest gradient flow increases. Conversely, the
increased southwesterly flow will also help scour the inversions
that have lingered northeast of the Mogollon Rim, with noticeably
warmer temperatures arriving by Friday.

There is some agreement that a sub-toical moisture tap develops by
the end of next week, perhaps resulting in some holiday rainfall. If
so, snow levels look to be well above 7000 feet at this time.

&&

.AVIATION...Wednesday 17/06Z through Thursday 18/06Z...VFR
conditions will persist. Look for light and variable winds
generally under 10 kts, except northeast winds of 10-20 kts at
KSEZ.

OUTLOOK...Thursday 18/06Z through Saturday 20/06Z...VFR conditions
are forecast. Winds becoming west to northwest at 5-15 kts on
Thursday strengthening to southwest at 10-20 kts on Friday.

&&

remain well above normal each day, along with dry conditions. Winds
southwest 5 to 15 mph on Wednesday tuning more westerly with gusts
as high as 20 mph Thursday.

Friday through Sunday...Expect daytime highs to remain well above
normal each day, along with continued dry conditions. Southwesterly
