Current Conditions: Clouds are beginning to break up some this Friday afternoon as high pressure starts to build in from the west. Both fine particle pollution (PM2.5) and ozone are down inside the good range. *** Saturday’s forecast: An Air Quality Action Day is in effect for Saturday! Mostly sunny skies and temperatures edging to around 90 degrees will permit rapid ozone development with some additional transport involved from the west. Maximum 8-hour concentrations of ozone will thus reach into the code ORANGE range during the afternoon. PM2.5 averages will be in the moderate range.

*** Sunday’s forecast: Conditions will be favorable for ozone concentrations on Sunday to climb into the code ORANGE range. Light southwesterly flow around a strong area of high pressure combined with sunny skies will allow for the rise in concentrations. Fine particulate will also go into the lower moderate range as well.

Residents and businesses within the ozone Air Quality Action Day area are strongly encouraged to voluntarily help reduce air pollution by:

• Conserving electricity by setting air conditioning to a higher temperature;
• Combining errands to reduce vehicle trips;
• Limiting engine idling; and
• Refueling cars and trucks after dusk.
