Air Quality Action Day has been declared for Susquehanna Valley on Friday, Jul 22

Friday, Jul 22: 105 AQI Unhealthy for Sensitive Groups Ozone
85 AQI Moderate Particle Pollution (2.5 microns)

Extended Forecast
Saturday, Jul 23: 90 AQI Moderate Ozone
85 AQI Moderate Particle Pollution (2.5 microns)
Current Conditions: As of 2 PM on Thursday, mostly sunny skies persist across the region as an area of high pressure continues to reside over the Mid-Atlantic region. Right now, southwesterly wind flow over the region is helping to drive temperatures into the upper 80s. The combination of the sunshine and the warm temperatures are helping to force ozone concentrations toward the Code YELLOW / ORANGE threshold. Expect deteriorating air quality to unfold tomorrow as high pressure continues to dominate our weather. *** Friday’s Forecast: So for Friday, sunny skies will continue to prevail across eastern PA as higher pressure pushes off to our east. The movement of the high will allow our winds to stay out of the southwest, forcing hotter, more humid conditions into the region. As a result, afternoon temperatures are likely to peak in the 90s. With increasing moisture levels and even hotter temperatures building in, expect ozone concentration to peak in the Code ORANGE status. PM 2.5 levels will also be on the increase due to the increasing humidity. *** Extended Outlook: Over the coming days, expect to see temperatures remain seasonably warm higher pressure builds in over the region. After the frontal passage on Friday, high pressure will move through the area. A slow moving front will begin to push in late in the weekend from the west. This front will provide more cloud cover and an increased chance of rain as it moves east through our area. After the front moves through, a new area of high pressure will build in over the Great Lakes area and continue to provide us with seasonably warm temperatures through the weekend. There will be another chance of rain by week’s end as a new storm system makes its way east. Overall, air quality levels during the week will be driven by warm and humid conditions over the area. However, it will likely be the level of activity across the region (with two new storm systems moving in early and late next week) that will keep air quality concentrations from exceeding the moderate threshold. –Nolan

Here are some Air Quality Action Day tips you can follow to help reduce pollution:

Days when ozone levels are expected to be high:

* Conserve electricity and set your air conditioner at a higher temperature.
* Choose a cleaner commute—share a ride to work or use public transportation. Bicycle or walk to errands when possible.
* Refuel cars and trucks after dusk.
* Combine errands and reduce trips.
* Limit engine idling.
* Use household, workshop, and garden chemicals in ways that keep evaporation to a minimum, or try to delay using them when poor air quality is forecast.

This forecast is brought to you by the Pennsylvania Department of Environmental Protection (PA DEP) and the Air Quality Partnership of the Susquehanna Valley.
