Synopsis and Discussion
OZONE:  Hot daytime temperatures and minimal cloud cover will promote
above average ozone production the next few days.  However, a low-level
westerly wind regime will help to keep ozone accumulation at below
average levels thru this forecast period.  As a result, expect highest
local ozone levels in the mid to upper-moderate range of the Air Quality
Index to occur over the east Valley thru this forecast period.   
PARTICLES:  Drier air has overspread much of southern AZ and summer
monsoon thunderstorm activity does not look likely even for areas east
and southeast of the metro area until Wednesday.  Thus, a low risk for
unhealthy levels of PM-10 due to dense blowing dust generated by outflow
boundaries will exist today and Tuesday before becoming moderate again
on Wednesday.  Until then, low-level gradient winds and upslope flow
will yield breezy to gusty conditions at times each afternoon.
