Area Forecast Discussion
National Weather Service Flagstaff AZ
340 AM MST Fri Dec 9 2016

.SYNOPSIS...Seasonably warm weather will continue through the
upcoming weekend. Expect periods of clouds with breezy conditions
developing on Saturday. Predominantly dry and mild weather will
persist into the middle of next week.


.DISCUSSION...Weak ridging will be over the region today into
Saturday bringing periods of mainly mid and high level clouds
along with seasonably warm temperatures. A weak wave expected to
move through the Great Basin Saturday will bring increased wind to
northern Arizona lasting through Saturday night. The wave moves
through the four corners region late Saturday night through
Sunday. There will be enough upslope flow and low level moisture
to generate low clouds and perhaps some drizzle or very light
precipitation. Have added very low precip chances to this period
over the high terrain from Flagstaff north.

Dry and mild weather under continued zonal flow persists through
the middle of next week. Operational model runs show the potential
for a colder trough to move into the southwest by Friday of next
week but confidence is still low at this point. Will maintain a
chance of showers and a trend toward cooler temperatures.


.AVIATION...For the 12Z forecast...Areas of low clouds with bases
2000-3000 FT AGL will continue through around 16Z northwest of a
KPRC-KPGA line...including the KGCN terminal. There is a low chance
of these cigs redeveloping after 05Z Sat in these areas.
Otherwise...expect VFR conditions under periods of mid and high
level clouds over the next 24 hours. Aviation discussion not updated
for TAF amendments.
