Alerts in force

An Air Quality Alert is issued by the National Weather Service on behalf of a state or local agency when pollution is expected to reach a level that harms health. An Air Stagnation Advisory means the air will not move enough to clear what is already in it.

None are in force near Summit Hill right now. All Pennsylvania warnings.

The forecaster’s discussion

Written by Pennsylvania Dept. of Environmental Protection for Lehigh Valley and filed with AirNow.

Current Conditions at 3 p.m. EDT this Wednesday afternoon: Skies are partly to mostly sunny across the area with a brisk east wind allowing for low levels of fine particle (PM2.5) and ozone. Good air quality continues through the period with east to northeast flow bringing in clean air. Here are the forecast details: *** Thursday’s forecast: Thursday brings mostly sunny skies with a cool northeasterly surface breeze and air pollutants at low concentrations. Afternoon temperatures near 70 degrees. *** Extended forecast: Nice early fall weather continues Friday into Saturday. A coastal low moving westward will bring in more clouds Saturday night into Sunday with perhaps a rain shower, then mostly sunny Monday with a nice afternoon. Air quality will average in the good range.---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 analysts have not drawn smoke over Summit Hill in satellite imagery today.

NOAA’s model forecasts no measurable smoke near the ground here over the next two days.

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.
