|Current conditions:**An Air Quality Action Day will be declared for the day Monday** Fine particulate concentrations are elevated in the code ORANGE range across most of the area this Sunday afternoon, and these levels will continue into the day Monday as a stagnant weather pattern continues. *** Monday’s forecast: A strong temperature inversion in tandem with weak low and mid level winds will allow for PM2.5 buildups during the day Monday. Code ORANGE concentrations of this pollutant are likely with mostly sunny skies and unseasonably warm temperatures. The highest concentrations will likely be across Lancaster County during the morning hours. *** Extended forecast: Air quality will improve Tuesday as a strong upper level ridge starts to break down and allows for an increase in low level winds, mixing, and dispersion. Nonetheless, moderate air quality is still likely. Further improvements to the good range will occur by Wednesday as a cold front approaches and brings an opportunity for some needed rainfall. Cooler air will follow this front late this week, with temperatures moving down closer to November normals.—McAuliffe|
