The forecaster’s discussion
Written by Pennsylvania Dept. of Environmental Protection for Susquehanna Valley and filed with AirNow.
Current Conditions at 3 p.m. EDT this Monday afternoon: Low pressure over West Virginia is spreading clouds and some light precipitation into south-central Pennsylvania. Fine particle (PM2.5) and ozone levels remain low. An unsettled pattern will continue through the next 36-48 hours. Here are the forecast details: *** Tuesday’s forecast: Overcast and cool with periods of rain Tuesday, with the heaviest coming through the early afternoon. Air quality will be in the good range with a brisk east to southeast wind as temperatures only get close to 60 degrees. Fall arrives Tuesday evening at 8:04 p.m. EDT. *** Extended forecast: Mostly cloudy Wednesday with a shower or two. Developing low pressure off the east coast should remain far enough out to sea to enable dry and cool conditions to prevail Thursday through Saturday with high pressure in control. Overall air quality will remain good with a northeasterly wind.---McAuliffe

Fine particles in micrograms per cubic meter, ozone in parts per billion as an 8-hour average. The index for each hour is EPA’s: the ozone figure is already the 8-hour average the ozone index is defined on, and the particle figure is run through EPA’s NowCast, which is how an hourly PM2.5 concentration becomes an index.
Smoke
NOAA’s Hazard Mapping System analysts drew light smoke over Newmanstown in satellite imagery today (Mon, 11:00 AM EDT to Mon, 1:00 PM EDT). That is smoke seen from above; it is not always smoke at ground level.
NOAA’s model forecasts no measurable smoke near the ground here over the next two days.
What this means
Good
Air quality is satisfactory, and air pollution poses little or no risk.
- Who is affected
- Nobody is expected to be affected.
- What to do
- It is a good day to be outside.
- Index range
- 0 to 50
Category descriptions are the Environmental Protection Agency’s own.
What these numbers are. An index beside a monitor’s name is a measurement, published hourly by AirNow and preliminary until the operating agency certifies it. A category for today or tomorrow is a state or local agency forecaster’s own forecast for a reporting area. An hourly index is NOAA’s air quality model on a five-kilometer grid, not a reading from any instrument. Where a town has no monitor within reach, only the model figures appear, and the page says so.
