Air Quality Action Day has been declared for Susquehanna Valley, on Thursday, Jul 7

Tomorrow’s Forecast
Thursday, Jul 7: 110 AQI Unhealthy for Sensitive Groups Ozone

Extended Forecast
Friday, Jul 8: 80 AQI Moderate Particle Pollution (2.5 microns)

Current Conditions: As of 2 PM on Wednesday, mostly sunny skies prevail over the region as higher pressure remains in control of our weather. We do remain sandwiched in between two weak frontal systems… one over Maryland and northern Virginia which triggered some shower development early today and the second over the Great Lakes. The one over the Great Lakes will end up pressing through our region by early tomorrow morning. Right now, temperatures remain warm with readings registering near the 90 degree mark. The sunshine today combined with these very warm temperatures are forcing ozone into the Code ORANGE threshold. PM 2.5 levels also remain elevated in the upper moderate range. Expect another Action Day tomorrow as the warm and humid conditions remain in place over our area. *** Thursday’s Forecast: So for Thursday, partly sunny skies will persist for much of the day after a cold front pushes through the region early in the morning. This front will end up stalling just south of the Mason Dixon line. Therefore, as the heat begins to build in the afternoon, we could see some isolated showers / thunderstorms develop over our area. For the most part, even with the frontal passage, the air mass should remain warm and moist. Therefore, even as high temperatures peak in the upper 80s, expect air quality levels to remain elevated. There will be enough carry over (from the high ozone today) that will drive ozone levels into the Code ORANGE threshold again.
