Air Quality Action Day declared for Susquehanna Valley on Thursday, Jan 7

Air Quality Action Day has been declared for Susquehanna Valley, PA, on Thursday, Jan 7
Tomorrow’s Forecast
Thursday, Jan 7: 105 AQI Unhealthy for Sensitive Groups Particle Pollution (2.5 microns)

Extended Forecast
Friday, Jan 8: 100 AQI Moderate Particle Pollution (2.5 microns)
Current Conditions: As of 2 PM on Wednesday, sunny skies persist over the region as a ridge of high pressure remains centered across the eastern US. The persistence of this ridge over our area has contributed to light winds and a rise in temperatures today. In fact, temperatures are approaching the 40 degree mark. The combination of the light winds and warmer temperatures has also allowed PM 2.5 levels to rise into the moderate range. With even warmer air building in tomorrow, expect PM 2.5 levels to peak near the Code YELLOW / Code ORANGE threshold. *** Thursday’s Forecast: So for Thursday, expect mostly sunny skies to persist once again as the ridge of high pressure remains in place across the eastern US. This ridge will allow for clear conditions during the morning hours. The clear conditions will, in turn, allow the ground to radiatively cool, reducing temperatures into the 10s. With relatively no wind to speak of, expect there to be limited mixing near the surface, increasing PM 2.5 levels across the area. An inversion will remain in place for much of the day, keeping PM 2.5 levels elevated near the Code YELLOW / Code ORANGE threshold, even as temperatures rise into the low 40s. This is why an Air Quality Action Day for PM 2.5 has been issued for the Susquehanna Valley region of PA. ***

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