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 New Eagle right now. All Pennsylvania warnings.

The forecaster’s discussion

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

Current Conditions at 4 PM EDT this Tuesday afternoon: Skies remain overcast across the area with showers lingering about. A brisk east wind has brought in very clean air, so fine particle (PM2.5) concentrations are rather low. While levels of this pollutant increase a bit over the next couple of days, good air quality is still expected. Here are the forecast details: *** Wednesday’s forecast: A morning shower, but continued mostly cloudy through the day with high temperatures reaching the middle 60s. Breezy east winds will again maintain low levels of PM2.5. *** Extended forecast: High pressure then controls the weather for the period Thursday through Saturday. Temperatures will slowly get back to normal over the weekend. Good air quality continues Thursday and Friday, but may deteriorate to moderate over the weekend as winds lighten and mixing is less.---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 New Eagle 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.
