 Air Quality Alert  Statement as of 9:35 am MST on May 29, 2015


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

The Arizona department of environmental quality in Phoenix has
extended an ozone high pollution advisory for the greater Phoenix
area through Saturday. The Pinal County department of air quality
has extended an ozone high pollution advisory for Pinal County
including Apache Junction... Casa Grande... Coolidge... and Florence
through Saturday.

This means that forecast weather conditions combined with existing
ozone levels are expected to result in local maximum 8-hour ozone
concentrations that pose a health risk. Adverse health effects
increase as air quality deteriorates.

Ozone is an air contaminant which can cause breathing difficulties
for children as well as persons with respiratory problems. A decrease
in physical activity is recommended.

If it is a regularly scheduled work day... you are urged to car pool...
telecommute... or use mass transit.

The use of gasoline-powered equipment should be reduced or done late
in the day.

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

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
920 am MST Sat may 30 2015 


Synopsis... 
hot and dry weather will persist over southeast California and 
southern Arizona this weekend with afternoon highs ranging from 
around 102 to 108 degrees for lower elevation population centers. 
Temperatures will cool somewhat heading into the middle of next 
week...coming closer to the seasonal normals. 


&& 


Discussion... 
regional upper air plots/satellite imagery reveal the upper level 
ridge over the southwestern states this morning...the axis with 585- 
587dm heights stretched over Southern California close to the lower 
Colorado River valley. Despite the thin high clouds...the drier 
anticyclonic flow currently in place over the region will once again 
bring mostly sunny skies to our forecast area. With the dry air... 
good solar heating and mixing potential...temperatures will quickly 
warm up as we go through the day. Current surface temperatures are trending 
a couple of degrees warmer than this time yesterday morning...so 
everything looks to be on track to have our maximum temperatures once again top 
out in the 103-107 degree range over the lower deserts this 
afternoon. No updates planned for the forecast. 


Previous discussion... 
water vapor imagery reveals a strengthening ridge off the Baja California 
coast...with an impressive atmospheric river of moisture moving 
toward the Pacific northwest. The big story through early next week will be the 
ongoing stretch of triple digit temperatures across the lower 
deserts. Many locations in the Phoenix area overachieved by a degree 
or two on Friday and not surprisingly...today's 00z deterministic 
and blended bias corrected guidance are advertising slightly warmer 
temperatures for the next few days. While the inherited forecast 
highs for Saturday through Monday were already in the ballpark...I 
made minor upward adjustments in most locations. Generally 
speaking...highs should range from 102-108 across the lower deserts 
each day through early next week. 


Also Worth mentioning...there will be a brief period on Sunday where 
a fair amount of bl moisture /6-7 g/kg bl mixing ratios/ is advected 
northward along the Arizona/nm border /courtesy of a transient middle level 
wind shift out of the southeast/. This has been advertised by most 
of the deterministic models for the past few days...now some of the 
hi-res guidance is starting to pick up on this moisture as well as 
the potential for a few isolated showers in the mountains east of 
Phoenix. The best chances of storms still appear to be well east of 
our forecast area where moisture will be higher. Not seeing any 
obvious triggers to fire off convection outside of normal 
differential heating/terrain circulations...thus I wouldn't expect 
areal coverage to be much more than 10-20 percent. Probability of precipitation adjusted 
slightly in the upward direction. 


By early next week an upper low will move through the Pacific northwest which 
will serve to lower heights and temperatures across much of the 
western Continental U.S.. direct impacts from this low will be negligible early 
in the week outside of a small drop in temperatures. The forecast 
becomes a bit more unclear from Wednesday/Thursday Onward as a 
secondary trough/low moves through the Great Basin. Exact track of 
the low is still up for debate among today's 00z GFS/ECMWF/Gem 
however ensemble based guidance suggests dry weather across the 
deserts and a small chance of mountain showers/tstorms. Seems more 
than reasonable based on the modest increase in bl moisture ahead of 
this trough. This secondary trough should also knock temperatures 
back a few more degrees...at least into the middle/upper 90s by late 
next week. 


&& 


Aviation... 
south-central Arizona including kphx...kiwa...and ksdl...and 
southeast California and southwest Arizona including kipl and 
kblh... 


Very similar conditions today anticipated for the terminals as high 
pressure remains over the region. Passing cirrus and afternoon high 
terrain based cumulus over the mountains of northern and eastern Arizona 
will be experienced. Winds will follow typical diurnal headings 
early...with the afternoon/evening shifts offset later and mostly light 
speeds. 




Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Monday through Friday... 
longwave troughing will develop back across the western states 
during the week which will help reign in some of the warmer 
temperatures and supporting periods of elevated breeziness... 
generally favoring southwest headings. Minimum humidities 
will generally remain below 10 percent on the lower elevations and 
below 20 percent on the higher terrain. Overnight recovery will be 
mostly fair.
