Area Forecast Discussion
National Weather Service Flagstaff AZ
333 PM MST Thu Sep 21 2017

.SYNOPSIS...Expect a cooling trend with windy conditions through
Friday. Cool conditions will persist over the weekend. Expect
freezing temperatures for much of the high country Saturday and
Sunday mornings.

&&

.DISCUSSION...
Windy conditions have developed this afternoon with many locations
gusting to 40 to 50 mph. Favored areas will see gusty winds
persist overnight, but most places will see winds decrease after
8pm. This is occurring ahead of a trough deepening across the
western United States. A cold front associated with this trough
will move across northern Arizona on Friday. Winds will continue
to be gusty on Friday, but will decrease from west to east through
the day as colder air filters into the state. A few showers may
develop along the front Friday and again across eastern AZ
Saturday. Minimum temperatures Saturday and Sunday morning will
likely drop below freezing in many areas of the high country,
generally above 6500 feet.

&&

.AVIATION...For the 00z package...Expect VFR conditions for the
next 24 hours. Look for south to southwest winds at 20-30 kts
with gusts from 30-40 kts...decreasing to 10-20 kts with gusts to
30 kts after 03Z. For Friday, after 17Z, southwest winds 15-25 kts
with gusts from 25-35 kts. Aviation discussion not updated for
TAF amendments.

&&

.FIRE WEATHER...On Friday, a mainly dry, cold front will move
across the northern Arizona causing breezy conditions and a
slight chance of thunderstorms. For Saturday, Look for lighter
winds and below normal temperatures with just a slight chance of
thunderstorms.

Sunday through Tuesday...Expect light winds and well below normal
temperatures all three days. Generally dry, but a bit of
