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 Lugoff right now. All South Carolina warnings.

The forecaster’s discussion

Written by South Carolina DES for Columbia and filed with AirNow.

As of Wednesday afternoon, all forecast regions are trending towards a code green finish. The cold air damming regime that dominated the region Wednesday will again be the primary driver for weather conditions on Thursday. Overcast skies and a daytime high temperature at a meager 70 degrees are forecast. The noticeably cooler temperatures and an uptick in wind to a moderate breeze out of the Northeast will act as a reprieve from what has been the overbearing late summer's heat stagnation of late. These favorable conditions are primed to inhibit surface ozone formation. A slight lessening of environmental moisture, while not usually a recipe for cleaner air quality, will do little to prevent what should be a remarkably clean day. Air mass sourcing from the North is also free from pollutants. Overall for Thursday, all forecast regions are forecast to peak in code Green.

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 Lugoff 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.
