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 Atoka County right now. All Oklahoma warnings.

The forecaster’s discussion

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

Temperatures are slowly returning to more seasonable levels across Oklahoma following the collapse of the heat dome. However, conditions are remaining warm, with high temperatures into the 90s, which will support ozone formation statewide. Ozone concentrations are expected to reach the Moderate/Yellow category in the latter half of this week for all parts of Oklahoma except the southeast portion of the state. Additionally, particulate matter concentrations into the Moderate category are expected along the I-35 corridor and in the Tulsa area by the end of this week. Storm chances are ongoing for this week through the weekend, with the potential for rainfall to provide localized air quality improvement.

Hour by hour

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 Atoka County in satellite imagery today (Wed, 7:00 AM CDT to Wed, 10:00 AM CDT). That is smoke seen from above; it is not always smoke at ground level.

NOAA’s model forecasts near-surface smoke peaking at 0.5 µg/m³ around Wed, 3:00 PM CDT.

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.
