PA DEP declares Air Quality Action Day for Dec. 29 in Susquehanna Valley

Current Conditions as of 1 PM on Wednesday: High pressure is providing mostly sunny skies with temperatures well into the 40s this afternoon. After a few days of frigid temperatures last weekend, we are looking to close out 2022 much warmer as we head into this weekend. *** Thursday’s Forecast: Thursday will be another mild day with temperatures climbing into the low 50s, which is several degrees above normal highs for this time of year. High pressure providing a light southwesterly breeze under mostly sunny skies will allow for the temperatures to warm nicely into the afternoon. Concentrations of fine particulate matter (PM-2.5) will climb as chilly overnight and early morning temperatures will lead to the formation of a strong temperature inversion with the much warmer air moving in over the area just above the surface. Hourly values of the PM-2.5 concentrations will be higher during the period that the inversion is in place, but the light afternoon winds as temperatures warm to break the inversion will only provide a limited amount of mixing. Therefore, concentrations will be in the high end of the moderate range on average for the day with some sites possibly averaging out in the Code Orange range. An Air Quality Action Day will be declared as a result.
