* AFFECTED AREA...The higher terrain of eastern Maricopa, Pinal 
  and southern Gila Counties including the Mazatzal and 
  Superstition Mountains. 

* TIMING...Now through this evening.

* WINDS...West winds 25 to 35 mph with gusts up to 50 mph.

* IMPACTS...Strong winds will create difficult and hazardous 
  driving conditions, especially for high profile vehicles. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Wind Advisory means that sustained wind speeds of between
30 and 40 mph are expected, or wind gusts of between 40 and
58 mph. Winds this strong can make driving difficult, especially
for high profile vehicles. In addition, strong winds over desert
areas could result in briefly lowered visibilities to well under
a mile at times in blowing dust or blowing sand. Use extra
caution.

.SYNOPSIS...
Near normal temperatures this weekend will cool drastically early
next week as a low pressure system drops southward through the
southern Rockies and Desert Southwest. There will also be a chance
of showers beginning Sunday night and continuing through early
Tuesday primarily across the higher terrain north and east of
Phoenix. In the wake of the low pressure system, cooler than normal
temperatures will persist into next weekend.

.DISCUSSION...
After fog had burned off this morning, only modest drying of the
boundary layer has occurred so far with weak advective processes at
work. Model mean output suggests further drying this afternoon such
that crossover dewpoint/ambient temperature thresholds may be more
difficult to achieve. Nevertheless while the synoptic setup is not
optimal for fog redevelopment, a few lower lying locations could see
more hazy/light fog conditions Sunday morning. Otherwise, a remnant
southern stream shortwave will shear into the mean flow ahead of
aggressive height falls progressing down the West Coast resulting in
increased cloud cover and moisture Sunday afternoon.

All models continue to indicate that a well defined deep trough will
drop southward into northern Arizona Monday and Tuesday. Ahead of
this system, vorticity and jet-forced ascent will increase; and the
cyclonic flow ahead of the trough and in association with moisture
fetch trailing the aforementioned remnant southern stream wave will
result in sufficient moisture transport for precipitation,
particularly into central Arizona. A very favorable upslope
component will generate areas of light rainfall, particularly across
the higher terrain from Phoenix north and eastward as early as
Sunday evening. In addition Sunday evening, robust height falls
surging into SE California will promote stronger winds and at least
a localized blowing dust threat.

Conditions will grow even more favorable for light precipitation
from Phoenix into higher elevations Monday along a steep frontal
boundary charging into central Arizona. While PWATs will be no where
near the levels experienced earlier in the week, this is a much
colder system and the favorable orographic component should
efficiently squeeze out whatever moisture is entrained along the
frontal boundary. Have made some rather marked increases to Pops
Monday feeling isold light showers forming on the foothills will lift
into a fairly good shield of light rain over the eastern parts of
the forecast area.

Latest hi-res WRFs also indicate that the anomalously strong wind
fields will translate eastward into breezy conditions at the surface
as height falls spread closer to the CWA. While its unlikely the
trough ends up stronger than forecast, some advisory type winds may
be possible; though fortunately, higher humidity levels will
preclude much of a fire danger. With such a pronounced cold core
system (H7 temperatures falling below -10C), have cut forecast highs
Monday and Tuesday closer to raw blended guidance and towards the
lower tercile of available model output. Across the higher terrain,
this cold core system will result in snow levels low enough for at
least a dusting of snow across the highest peaks. Although the
probability of a freeze event becomes increasingly unlikely through
February, there is a slight chance that outlying lower desert
locations will drop just below freezing Wednesday morning.

Latest extended guidance indicates that a longwave trough will
persist across the Intermountain West through next weekend. This
will generally result in cooler than normal conditions along with
the passage of a few short wave troughs. However, both the GEFS
and EPS show little potential for significant precipitation.

.AVIATION...
South-Central Arizona including KPHX, KIWA, and SDL:

SCT-BKN high cirrus decks and light easterly winds tonight and early
Sunday to give way to increasing westerly winds and lower cigs by
Sunday afternoon/evening as a cold front/associated Pacific upper
low approaches the region from the northwest. FEW-SCT cloud layers
in the 6-8k foot range are likely to develop by Sunday afternoon,
with these cloud layers expanding into the SCT-BKN range along with
the development of scattered light showers by Sunday evening.
Westerly winds are expected to continue through Sunday night with
gusts as high as 25 knots possible.

Southeast California/Southwest Arizona including KIPL and KBLH:

Light winds tonight and early Sunday to give way to increasing
westerly winds Sunday afternoon/evening as a cold front/associated
Pacific upper low approaches the region from the northwest. Wind
speeds as high as 20 knots with gusts as high as 30 knots are likely
by Sunday afternoon at both KIPL and KBLH, along with possible
blowing dust (confidence is too low to include blowing dust in the
tafs at this time). SCT-BKN high cirrus decks to prevail at both
terminals through the taf period.

Aviation Discussion not updated for amended TAFs.

.FIRE WEATHER...
Monday through Friday:
A low pressure system will bring a chance of precipitation, mainly
to the higher terrain north and east of Phoenix through Tuesday
morning. However, rain totals will generally remain below a tenth
of an inch. Cooler and drier conditions are expected behind this
system with below normal temperatures persisting through the week.
