[ADEQ Forecasts] ADEQ Daily Air Quality Forecast - Saturday, September 25, 2010

Fri Sep 24 11:49:09 MST 2010

Health message for Friday, September 24: No health impacts are expected.

Health message for Saturday, September 25: Unusually sensitive people should consider limiting prolonged or heavy exertion 0utdoors.

Synopsis and Discussion:
High pressure will push afternoon temperatures across the Valley well above normal through early next week.  We're facing highs around 104-106°F Saturday through next Wednesday under mostly sunny skies and light winds.  This is great news for those planning activities that include swimming pools.  Normal for this time of year is only 96°F.  Temperatures will trend down into the upper 90s by the end of next week, but still above normal.
Once again, Thursday's air quality in the Phoenix forecast area was in the GOOD range for all pollutants.  With high pressure keeping winds fairly light, we should see ozone concentrations climb into the lower MODERATE range this weekend.  A light east-to-west flow will put the highest levels in the west part of the Valley.  This means places such as Glendale, Dysart and Buckeye should see the highest levels this weekend.  Particulates are expected to stay in the middle to upper part of the GOOD range during this period.

Check back on Sunday for the latest.  Until then, have a great weekend!  -J.Paul
