Area Forecast Discussion
National Weather Service Flagstaff AZ
159 AM MST Tue Nov 21 2017

.SYNOPSIS...High pressure will continue to strengthen over Arizona
through much of this week. Daytime temperatures will warm enough
by Wednesday, Thanksgiving and Friday to challenge long standing
high temperature records.

&&

.DISCUSSION...High pressure will build over Arizona during the
course of the next few days and essentially remain over the state
through the Thanksgiving holiday weekend. The main impact of this
pattern will be to develop a very warm air mass. The result will
be warming daytime temperatures to near record levels starting
Wednesday and lasting into Saturday. We are expecting high
temperatures a good 15 to 20 degrees above normal, essentially
state wide. Otherwise, look for mainly light winds under periods
of high level clouds. There will probably be a bit of cool down
late in the weekend into early next week as a shortwave trough
brushes Arizona.

Generally dry conditions are expected for at least the next ten
days.

&&

.AVIATION...For the 12Z package...Expect VFR conditions under
periods of considerable upper-level cloudiness over the next 24
hours. Local IFR conditions will continue through the morning at
KGCN due to smoke from a nearby burn. N-NE winds 5-15kt developing
during the late morning and afternoon hours. Aviation discussion not
updated for TAF amendments.

&&

.FIRE WEATHER...The persistent pattern of dry and unseasonably warm
weather with generally light winds will continue through Saturday as
strong high pressure builds over the state. Daytime temperatures are
on a warming trend through Friday, with highs becoming 15 to 20
degrees above normal. High temperature records may be set Wednesday
through Friday.

&&

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