Synopsis and Discussion
*A PM-10 HIGH POLLUTION ADVISORY REMAINS IN EFFECT FOR THURSDAY, MARCH
26, 2009*
   Winds have yet to pick up here in the Valley Thursday morning, but
they will by around 2pm if not sooner.  Possible gusts near 40 mph will
likely generate blowing dust that reduces visibility to less a mile in
some isolated desert areas at times.  No rain is expected with this
system, so residual dust may hang around for much of the day on Friday
as well.  There should be a nice break on Saturday with afternoon desert
temperatures returning to the lower 80s, allowing further dispersion of
lingering dust.
   The weather pattern looks like it will remain fairly unchanged for
the next 7-10 days with the large trough of low pressure remaining
anchored over the central U.S.  For Arizona, this means that we can
expected wind-producing disturbances to pass through the region every
few days.  Following Thursday's event, another slightly weaker system
will move through Sunday afternoon through early Tuesday morning.
Models suggest a third disturbance could produce more blowing dust next
Thursday.  It's possible there could be one or two more High Pollution
Advisories during this period as rain will stay just out of range.
Allergy sufferers as well as people with respiratory issues may want to
keep a close eye on the forecast through next week as outdoor activities
may be hindered due to blowing dust and pollen.  Check back tomorrow for
a closer look at the weekend weather and related air quality.  Until
then, have a good day!
