Area Forecast Discussion
National Weather Service Flagstaff AZ
437 PM MST Wed May 8 2024

.SYNOPSIS...Below normal temperatures will continue through the
end of the week, with near/above afternoon highs returning over
the weekend. Typical spring-like breezes will remain through the
forecast period, with slight chances for showers and thunderstorms
across some areas Friday through Monday.

&&

.DISCUSSION...The large area of low pressure that brought the
strong winds to northern Arizona on Monday is now over the Great
Plains. There is also a large area of high pressure off the West
Coast. Arizona is between these two atmospheric features...in a
zonal or westerly flow. The low will slowly fill as it moves
southwest and over Utah by Thursday afternoon. Even though the low
pressure approaches Arizona, our pressure will increase and will
slowly increase our temperatures through the end of the week. Most
of northern Arizona have afternoon highs staying a few degrees
below-normal for this time of year. Will will see afternoon
seasonal southwest breezes for the next few days as well.

By late Thursday, enough moisture and instability returns to
northeast Arizona for a few showers and/or thunderstorms. The low
remains over the area through the weekend with low chances for
showers and thunderstorms remaining into next week...with the best
chances along our Utah and New Mexico border. Again, even with the
low over the area, the surface pressure will increase with
temperatures warming to above average by Sunday for many area.

There will also be areas of smoke from prescribed burns and wild
fires that could reduce the visibility at times this week.

.AVIATION...Thursday 09/00Z through Friday 10/00Z...Widespread VFR
conditions and mainly light winds from variable directions are
forecast. However, northeast winds tonight could become gusty in
some spots, including KSEZ and KGCN. And, visibility reductions
are possible at KFLG, mainly overnight, due to smoke from a nearby
prescribed fire.

OUTLOOK...Friday 10/00Z through Sunday 12/00Z...Mainly VFR
conditions and light winds are forecast. A few showers and
thunderstorms are possible northeast of a KGCN- KRQE line each
day. Areas of smoke and haze are also possible.

&&

.FIRE WEATHER...Thursday and Friday...Dry and cool conditions with
breezy afternoon winds are expected for Thursday and Friday.
Anticipate minimum humidity of 10 to 15% each afternoon with
moderate to good recovery by Friday night. Elevated northeast winds,
10 to 12 mph, are likely tonight across the High Country, followed

afternoons.
