 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.

For details on this high pollution advisory for Maricopa County...

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
315 PM MST Friday Oct 31 2014 


Synopsis... 
significantly cooler readings are expected for the weekend...as a 
low pressure system and cold front push through the Desert 
Southwest. Highs in the lower deserts will drop into the upper 70s 
or low 80s on Saturday and fall to the lower 70s on Sunday. In 
addition to the cooler temperatures...periods of breezy conditions 
can be expected throughout the weekend. Rain chances will be slight 
and confined mostly to the higher terrain east of Phoenix. A gradual 
warming trend will begin Monday into the middle of next week. 


&& 


Discussion... 
forecast area is situated between an upper level ridge to the east 
and a trough off the West Coast. Veering profile is also evident 
with east winds in the lower levels and a stronger southerly flow at 
700 mb. Downslope component to the flow has persisted this 
afternoon...resulting in well above average temperatures due to warm 
advection and the effects of compression. Current high temperature 
of 95 degrees in Phoenix is only one degree shy of the daily record 
last set in 1988. 


Hrrr continues to suggest that isolated convection will develop this 
afternoon...though consensus among the hi-res and global guidance is 
that this will be well to our south and east...where instability and 
deep layer shear will be maximized. Across the lower 
deserts...mainly clear skies will persist followed by increasing 
high clouds this evening. 


&& 


Previous discussion... 
model guidance...including GFS ensemble members...remain consistent 
in calling for the deep and cold trough to push across Arizona this 
weekend...bringing much cooler temperatures...a slight chance for showers 
across south central Arizona...and breezy/locally windy weather on 
Saturday. The trough will move through as a series of waves...with the 
first wave quickly racing northeastward and across the state 
Saturday. The first cold front Saturday will lead to about 10 
degrees of cooling to go along with breezy or locally windy 
southwest winds. Moisture and dynamics will be somewhat limited so 
precipitation will be confined to areas mainly north and east of 
Phoenix...across the higher terrain...and probability of precipitation will stay mostly 
below 15 percent. The second...and stronger...wave moves across the 
state Sunday into Sunday night...and the GFS actually develops a 
closed upper low that treks across northern Arizona during the day. Stronger 
dynamics are being advertised...as the 300 mb jet dives further to the 
south putting south central Arizona under the favored front left quadrant of 
the jet. Also...an impressive bullseye of middle level q convergence is 
forecast to push across much of central and northern Arizona. With temperatures 
being much cooler relative humidity values will be higher...and it will be easier 
to wring smaller amounts of quantitative precipitation forecast out of the atmosphere. As such we 
raised probability of precipitation into the 15-20 percent ballpark over south central Arizona on 
Sunday...including the Lower Desert areas. High temperatures are expected 
to drop another 10 degrees or so with highs in the greater Phoenix 
area to fall to near 70 degrees. Those numbers would represent highs 
more than 10 degrees below seasonal normals. 


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 72 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 developing 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. Very low 
confidence in the European model (ecmwf) solution as model run to run consistency has 
been very low. For now...will keep a dry forecast in place across Arizona 
for Wednesday and Thursday...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... 
through 03z Sat...scattered cirrus clouds. South to southeast wind 10 to 20 
knots. 03z Sat to 17z Sat...scattered cirrus clouds. Light southeast wind 
under 7 knots. From 17z Sat to 23z Sat...dry cold front approaching. 
Scattered to broken clouds near 8 thousand above ground level. Increasing afternoon southwest wind 
15 to 23 knots. 


Southeast California and southwest Arizona including kipl and kblh... 
through 08z...scattered cirrus. South to southwest wind 10 to 20 knots. 
From 08z Sat to 17z Sat...scattered cirrus clouds. South to southwest wind 
near 10 knots. From 17z Sat to 23z Sat...dry cold front approaching. 
Scattered clouds based near 8 thousand above ground level. Increasing southwest wind 15 to 25 
knots.

Fire weather... 
Monday through Friday... 
a cooler airmass will settle over the region Monday through

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.
