* O3 = Ozone      CO = Carbon Monoxide      PM-10 = Particles 10 microns
& smaller      PM-2.5 = Particles smaller than 2.5 microns

 

*"Ozone Health Watch" means that the highest concentration of OZONE may
approach the federal health standard.

"PM-10 or PM-2.5 Health Watch" means that the highest concentration of
PM-10 or PM-2.5 may approach the federal health standard.

"High Pollution Advisory" means that the highest concentration of OZONE,
PM-10, or PM-2.5 may exceed the federal health standard.

"DUST" means that short periods of high PM-10 concentrations caused by
outflow from thunderstorms are possible.

Health message for Monday, June 25:   Unusually sensitive people should
consider limiting prolonged or heavy exertion outdoors. 

 

Health message for Tuesday, June 26:   Unusually sensitive people should
consider limiting prolonged or heavy exertion outdoors. 

 

Synopsis and Discussion

A rather persistent weather pattern is expected the next few days as the
mean trough position remains located over the northeast Pacific.  The
southern end of this feature will bring very dry and relatively light
westerly flow aloft over Arizona and keep deep summer monsoon moisture
suppressed to the east and southeast of the state.  It will also tend to
augment valley afternoon breezes that are instrumental in keeping local
ozone dispersion above average and hence its levels below their
potential.  For now a near-persistence type forecast seems appropriate
since no significant swings in air pollutant concentrations are
indicated.
