None are in force near Durant right now. All Oklahoma warnings.

The forecaster’s discussion

Written by Oklahoma Department of Environmental Quality for Ardmore and filed with AirNow.

Winds out of the north east will keep pollutant levels low for most of the state through Wednesday. A southerly wind shift beginning Thursday paired with warm temperatures will push ozone into the moderate category for the back end of the week in most areas.

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.

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.
