Air Quality Action Day has been declared for Susquehanna Valley, PA, on Thursday, May 30

Tomorrow’s Forecast
Thursday, May 30: 102 AQI Unhealthy for Sensitive Groups Ozone
70 AQI Moderate Particle Pollution (2.5 microns)

Extended Forecast
Friday, May 31: 100 AQI Moderate Ozone
75 AQI Moderate Particle Pollution (2.5 microns)
Current Conditions as of 1 PM on Wednesday: Mostly sunny skies have developed this afternoon after dense fog blanketed most of the region early this morning. Temperatures are already into the 80s and we should see a number of 90 degree readings over the next several days. High pressure will provide the hot and humid conditions along with deteriorating air quality levels through at least Saturday. *** Thursday’s Forecast: Patchy fog possible again early Thursday, though not nearly as dense as Wednesday morning. This fog should be quicker to burn off Thursday morning than Wednesday as well, helping temperatures quickly climb back into the 80s by early afternoon. Highs for the day should push into the low 90s for a number of locations under mostly sunny skies. PM 2.5 levels will reach their highest values for the day once again during the morning, though these values will not be as high as early Wednesday, and will remain in the middle of the moderate range for the day. Light west/southwesterly flow with the ample sunshine will allow Ozone concentrations to climb well into the moderate range. Some locations are even likely to see concentrations peak just into the Code Orange range. Air quality conditions will continue to deteriorate into Friday.
