Area Forecast Discussion
National Weather Service Flagstaff AZ
354 AM MST Wed Dec 7 2016

.SYNOPSIS...A cold front moving through the area today will bring
cooler temperatures and variable cloudiness. Some light
precipitation or drizzle is possible through the morning.
Otherwise, expect dry weather for the next several days.
Temperatures will warm Thursday into Friday and remain above
average through early next week.


.DISCUSSION...A long wave trough remains over much of the central
and western United States this morning. A shortwave feature over
Utah early this morning will push east into Colorado by this
afternoon dragging a cold front through northern Arizona. A
shallow layer of low level moisture has snuck into the area ahead
of the front resulting in areas of low stratus clouds this
morning. The low clouds and perhaps some fog will persist through
mid morning with some very light precipitation or drizzle possible.
We expect by afternoon the drier northerly flow will decrease
cloud cover. The most pronounced cooling today will be generally
north of Flagstaff from Grand Canyon towards the four corners
where daytime temperatures will be 5 to 10 degrees colder.

Predominantly dry and mild weather is in store through the
remainder of the forecast period as a generally zonal flow
develops. Periodic shortwaves moving through the zonal flow
pattern will result in periods of increased cloud cover and slight
temperatures fluctuations, but overall expect a dry and mild
period of weather through the middle of next week.


.AVIATION...For the 12Z forecast...Expect VFR conditions across
most of northern Arizona for the next 24 hours. However, some
mainly higher elevation locations including KFLG, KGCN, KSEZ
will see a period of low ceilings and possible fog with MVFR/IFR
conditions through 15-17Z this morning. Aviation discussion not
updated for TAF amendments.
