Area Forecast Discussion
National Weather Service Flagstaff AZ
911 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.

&&

.UPDATE...Winds have decreased over the region this evening and
the Wind Advisory has expired. Breezy conditions will persist
overnight and into Friday as a cold front moves into the region.
Sent some minor updates to cloud cover overnight and into Friday
morning to account for some low clouds over upslope areas of the
higher terrain. Rain chances ahead of the front are low, with the
best chance over the Kaibab Plateau through Friday morning.

&&

.PREV DISCUSSION /333 PM MST/...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 06z package...Expect mostly VFR conditions for
the next 24 hours. Look for south to southwest winds at 10-20 kts
with gusts to 30 kts possible over night, especially along higher
terrain. MVFR conditions are possible between 11Z and 16Z over
higher terrain from Flagstaff northward. Winds southwest at 15-25
kts with gusts from 25-35 kts after 17Z. Aviation discussion not
updated for TAF amendments.

&&

.FIRE WEATHER...On Friday, a mainly dry cold front will move
across 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 additional
moisture will sneak over eastern portions of the area on Tuesday for
a slight chance of showers and thunderstorms.

&&

.FGZ WATCHES/WARNINGS/ADVISORIES...NONE.
