Area Forecast Discussion
National Weather Service Flagstaff AZ
912 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.


No significant changes at this point, a brief chance for light
flurries this morning as low level moisture remains in the area.
Otherwise no significant weather is anticipated in the near term.


.PREV DISCUSSION /354 AM MST/...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 18Z forecast...Expect VFR conditions across most
of northern Arizona for the next 24 hours. However, some mainly
higher elevation locations including KFLG, KGCN, KSEZ may see
periods of MVFR ceilings, around 2000 feet AGL, throughout the day.
Confidence is low, so will hold off on including this in the TAF
forecasts for now. Aviation discussion not updated for TAF amendments.
