Air Quality Action Day has been declared for Susquehanna Valley, PA, on Wednesday, Dec 4

The Pennsylvania Department of Environmental Protection has declared an air quality action day for Dec. 4.

Tomorrow’s Forecast
Wednesday, Dec 4: 110 AQI Unhealthy for Sensitive Groups Particle Pollution (2.5 microns)

Current Conditions as of 1 PM on Tuesday: Hazy conditions continue this afternoon as calm winds are keeping mixng to a minimum, allowing for PM 2.5 levels to remain in the Code Orange range. Similar conditions will continue tomorrow before we begin to see a more active pattern return late week. *** Wednesday’s Forecast: Light winds will limit vertical mixing, yet again, through at least the morning and into the afternoon on Wednesday. Increasing moisture will continue to slowly push northward, bringing some milder temperatures with it. The combination of minimal mixing and rising moisture will allow for PM 2.5 levels to remain inside the Code Orange range through at least the middle of the day. The air mass to our south that contains the higher moisture levels is slightly cleaner than the current air mass in place. Therefore, as this air mass begins to push further north we should see concentrations begin to fall and reach the lower end of the Code Orange range if not high moderate by late in the day. A southerly breeze at the surface will form late afternoon to early evening to assist in pushing this mild and humid air mass northward. As a result, there will be enough hours of Code Orange concentrations throughout the day before we see improvement back to more moderate levels by late evening.
