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 Red Oak right now. All Oklahoma warnings.

The forecaster’s discussion

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

The residual northerly winds from last weekend's cold front will restrict ozone and particulate matter concentrations to the Good/Green category statewide today. Ozone concentrations into the Moderate/Yellow category will return to the metros beginning Wednesday, with higher Moderate values later this week as southerly winds return. Particulate matter concentrations are expected to reach the Moderate category for much of the state for the second half of the week, as southerly winds carry smoke into Oklahoma.

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.
