 Air Quality Alert  Statement as of 11:51 am MST on October 31, 2014


... High pollution advisory for Maricopa County including the greater
Phoenix area Saturday...

The Arizona department of environmental quality in Phoenix has issued
an airborne coarse particle high pollution advisory for the greater
Phoenix area for Saturday.

An episode of strong and gusty winds is forecast to generate
widespread blowing dust that may result in local coarse particle
concentrations that pose a health risk. Adverse health effects
increase as air quality deteriorates.

Coarse particulate matter - also known as PM-10 - is an air
contaminant that can aggravate heart and lung disease conditions...
especially in older adults... children... and those with asthma. A
decrease in physical activity is recommended.

Consolidate your travel... stabilize loose soils... slow down or avoid
travel on dirt roads... reduce or eliminate fireplace use... and avoid
using gas-powered lawn equipment.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
300 am MST Sat Nov 1 2014 


Synopsis... 
significantly cooler temperatures will arrive this weekend as a low 
pressure system and cold front push through the Desert Southwest. 
Highs will drop into the upper 70s and low 80s on Saturday...falling 
further to the upper 60s and lower 70s on Sunday. In addition to the 
cooler temperatures...occasionally breezy conditions can be expected 
throughout the weekend. Rain chances will be slight...confined 
mostly to higher terrain north and east of Phoenix...and amounts 
very light. A gradual warming trend will begin during the middle of 
next week as higher pressure aloft returns to the area. 
&& 


Discussion... 
deep and cold Pacific upper trough continued to push inland and into 
the California coast early this morning...and the latest plots showed the 
ridge weakening and moving off to the east with 30-70m 500mb height 
falls noted across portions of Southern California...Nevada and Arizona. Infrared imagery at 2 
am showed a band of middle/hi clouds spreading across Arizona just ahead of 
the approaching cold front...and also showed quite a bit of low 
cloud/stratus moving into northern Baja California and Southern California ahead of the main 
trough. Latest San Diego sounding showed the marine layer deepening to 
about 800mb...and this low level moisture should continue to deepen 
and eventually spread over the coastal mountains and into Arizona... 
enhancing precipitation chances for mainly south central Arizona. 


Guidance remains consistent that the trough will move through the area 
in two phases. The first wave will move quickly northeast and across 
Arizona today...as a cold front quickly races east across the 
deserts. Dynamics will be a bit limited as the main upper jet will 
stay off to our northwest...and only modest q convergence and upward vertical velocity 
will overspread the deserts. Main threat for showers or 
thunderstorms today will focus across the higher terrain areas to 
the north of Phoenix...although slight chance probability of precipitation will remain in 
the greater Phoenix area. Expect high temperatures to fall at least 10 
degrees with the cooler deserts lowering into the middle 70s to 
around 80. The strongest wind with the trough passage will occur 
today...with breezy to locally windy weather expected across much of 
the western deserts including favored higher terrain areas of Joshua 
Tree np...and portions of Imperial County such as el centro and 
Imperial. For the most part...except for an occasional gust...winds 
should remain below Wind Advisory criteria today. 


The second phase of the trough passage will occur Sunday/Sunday night 
as the main cold core of the low pushes east across central/northern 
Arizona and the best dynamics move across the County Warning Area. A very impressive middle 
level q convergence bullseye develops and moves across most of 
Arizona Sunday...and the upper jet dives further to the south 
putting south central Arizona under the favored front left quadrant for 
enhanced lift. Brisk low/middle level southwest winds will also provide 
orographic lift...especially over higher terrain areas to the north 
and east of Phoenix. As such...we will keep chance probability of precipitation going aross 
much of south central Arizona during the day Sunday. Despite strong 
dynamics Sunday...moisture remains a bit limited with precipitable water values 
mostly at or below 0.75 inches and as such we do not expect the 
precipitation that falls to be especially heavy. Most rainfall totals 
should stay well below one quarter of an inch. With a secondary cold 
front moving across the deserts Sunday...high temperatures will fall 
another 5-8 degrees with the cooler deserts dropping into the upper 
60s to low 70s. 


By Monday morning the trough axis will have shifted southeast of the 
greater Phoenix area...putting most of the County Warning Area under a subsident 
northwest flow aloft. Moisture will continue to thin...with skies to 
become mostly sunny by early afternoon over all but the high terrain 
of southern Gila County. Little change in high temperatures is expected...as 
cooler air continues to filter over the lower deserts. The forecast 
high for Phoenix Monday will be just 73 degrees. 


Dry north to northeast flow aloft continues across the area in the 
wake of the departed upper trough on Tuesday...for generally sunny 
skies. High temperatures will rise a few degrees as heights/thicknesses 
start to climb...but overall temperatures will stay below seasonal normals 
with Phoenix sitting in the middle to upper 70s. 


Quite a bit of model uncertainly persists for the latter portion of 
the extended period. GFS keeps high pressure aloft in place across 
the Desert Southwest...and develops a closed low well off to the 
southeast...over portions of Texas and northern Mexico. On the other 
hand...the European model (ecmwf) develops that same upper low much further to the 
west...and actually moves the low center into southeastern Arizona by Wednesday 
afternoon. The low starts to advect quite a bit of moisture into 
southeastern Arizona...some of that moisture tropical in nature. Continued low 
confidence in the European model (ecmwf) solution as model run to run consistency has 
been very low. Also...in the recent past GFS has outperformed the 
European model (ecmwf). For now...will keep a dry forecast in place across Arizona for 
Wednesday into Friday...but will keep some single digit probability of precipitation in 
place from Phoenix eastward...and add in some cloud cover as 
well...in a nod to the model uncertainty. 


&& 


Aviation... 
south-central Arizona including kphx...kiwa and ksdl... 
aviation impacts will be tied to both the possibility of lower ceilings 
and shifting and gusty winds Saturday. Increasing moisture will lead 
to eventual development of lower ceilings Saturday after sunrise...with 
both bufr soundings and statistical guidance support ceilings in the 
4k-6k level. While confidence is moderate regarding the presence of 
lower clouds...the persistence of clouds and timing of development 
and subsequent scattering later in the day carry much lower 
confidence. Scattered virga will be likely... and a few 
sprinkles/showers may also be briefly possible. While some higher 
wind gusts may be possible with the wind shift to the southwest late 
Saturday morning...speeds should remain below 25kt. 


Southeast California and southwest Arizona including kipl and kblh... 
gusty winds and timing of wind shifts will be the primary aviation 
impacts through Saturday afternoon. A cold front will pass through 
terminal sites Saturday morning with the possibility of variably 
shifting winds around frontal passage. During the afternoon hours...stronger 
west and southwest wind gusts approaching 30kt may be possible 
before decoupling around sunset. Forecast confidence is moderate. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Monday through Friday... 
a cooler airmass will settle over the region Monday through 
Wednesday. Afternoon temperatures will be slightly below normal... 
but warming in the week. Breezy north to northeast winds are 
expected both day and night Monday through Wednesday...generally in 
the 10 to 15 miles per hour range with gusts to 20 miles per hour possible. Lighter wind 
will develop late in the week. Minimum relative humidities will 
generally range from 15 to 20 percent. Overnight recovery will be 
poor Monday through Wednesday with the breezes.
