Tomorrow’s Forecast
Thursday, Aug 4: 102 AQI Unhealthy for Sensitive Groups Ozone
58 AQI Moderate Particle Pollution (2.5 microns)

Extended Forecast
Friday, Aug 5: 60 AQI Moderate Ozone
54 AQI Moderate Particle Pollution (2.5 microns)
Current Conditions: Mostly sunny skies prevail this Wednesday afternoon. Temperatures close to the 90-degree mark are allowing ozone to move into the lower moderate range today. Low relative humidity is keeping fine particle pollution (PM2.5) down inside the good range. Tonight will be mostly clear with temperatures only falling into the lower 70s. *** Thursday’s forecast: An Air Quality Action Day has been declared for Thursday as it will turn out to be the hottest day of the week with sunshine and a few clouds and temperatures maxing out in the lower and middle 90s. Ozone development will be more rapid, with parts of the area reaching the code ORANGE range during the afternoon. PM2.5 averages will reach the moderate zone.

DEP declares Ozone Action Day for Aug. 25

DEP has declared an Air Quality Action Day due to OZONE pollution in the Susquehanna Valley, PA, for Wednesday, Aug 25

Tomorrow’s Forecast
Wednesday, Aug 25: 102 AQI Unhealthy for Sensitive Groups Ozone
57 AQI Moderate Particle Pollution (2.5 microns)
Extended Forecast
Thursday, Aug 26: 98 AQI Moderate Ozone
57 AQI Moderate Particle Pollution (2.5 microns)

Current conditions: A ridge of high pressure building into Pennsylvania is bringing mostly sunny skies and hotter air into the area this Tuesday afternoon. Ozone levels are increasing, but remain in the good range. However, particle pollution (PM2.5) remains moderate in parts of the area. Deteriorating air quality is in store for the next couple of days with light winds, mostly sunny skies, and recirculating air. *** Wednesday’s forecast: An Air Quality Action Day is in effect for Wednesday!! Ozone formation during the late morning/afternoon will be robust, and 8-hour maximum concentrations are expected to reach into the code ORANGE range. PM2.5 levels will remain in the moderate range through the day as skies will be mostly sunny with temperatures reaching into the middle 90s. *** Extended forecast: The heat is expected to continue Thursday, with sunshine for the most part, and again, code ORANGE ozone concentrations are possible. Chances for afternoon and evening thunderstorm activity may temper the heat and subsequent ozone formation Friday into Saturday, so only moderate ozone and PM2.5 concentrations may occur on these days. It might not be until early next week until we can get a bonafide cold front to pass through and cool things off just in time for the start of September. —McAuliffe

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.

Clean Air is Good for Birds too

Study: Air pollution laws aimed at human health also help birds

U.S. pollution regulations meant to protect people from dirty air are also saving North America’s birds, according to a new study. Improved air quality under a federal program to reduce ozone pollution may have averted the loss of 1.5 billion birds during the past 40 years, the study found. That’s nearly 20% of bird life in the United States today.  Read more.

DEP Issues a Code Orange Air Quality Action Day Forecast for June 9, 2020

Harrisburg, PA – The Pennsylvania Department of Environmental Protection (DEP) and its regional air quality partnerships have forecast a Code Orange Air Quality Action Day for ozone on June 9, 2020, for southeastern and southcentral Pennsylvania (encompassing the counties of Bucks, Chester, Cumberland, Dauphin, Delaware, Lancaster, Lebanon, Montgomery, Philadelphia, and York).
Strong sunshine, temperatures close to 90 degrees Fahrenheit, and light south to southwest winds will act to bring ozone concentrations to code ORANGE levels Tuesday afternoon. Concentrations of ozone are expected to be lower on Wednesday with only partly sunny skies and the chance for shower and thunderstorm development.
On air quality action days, young children, the elderly, and those with respiratory problems, such as asthma, emphysema, and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities.  Read more
