Synopsis and Discussion
*An Ozone Health Watch AND a PM10 Health has been issued for Wednesday,
April 30, 2008*
Ozone levels continue to hold in the mid to upper "Moderate" range with
little relief.  It's only going to get worse before it gets better as a
trough of low pressure moves through the western U.S. the next couple of
days.  The tail end of the disturbance will impact Arizona Wednesday
with winds increasing to 30 mph at times across the deserts, even
stronger in higher elevations of Arizona.  Yuma is already indicating
that another transport situation is underway with Ozone in the upper
"Moderate" range on Tuesday.  That means that today and likely tomorrow
should see some high levels across the Phoenix forecast.  An increase in
winds also means we could see areas of blowing dust across the dry
deserts (now 65 consecutive days without measurable rain in Phoenix).
As a result of this latest weather system and its potential impact on
the Valley's air quality, we are issuing both an Ozone and PM10 Health
Watch for Wednesday.  The situation will be re-evaluated tomorrow, but
conditions should improve Thursday and Friday as the system exits the
region.  Check back then for the latest.  Have a good day!  -J.Paul
