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 Nash right now. All Texas warnings.

The forecaster’s discussion

Written by Louisiana Department of Environmental Quality for Shreveport and filed with AirNow.

Saturday, light southeasterly to southerly winds will hinder dispersion and allow regional thin smoke and other pollutants to linger over Louisiana. Furthermore, sunny and hot conditions will continue to promote ozone formation. Therefore, AQI levels will be low- to mid-Moderate in most locations, with high-Moderate AQI levels expected in Baton Rouge. Sunday and Monday, as surface high pressure settles over the Bayou State, light and variable winds will inhibit dispersion, allowing pollutants to remain over the state. In addition, mostly sunny and hot conditions will be conducive for ozone production each afternoon. Thus, AQI levels will be low- to mid-Moderate in most cities on both days.

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 Nash in satellite imagery today.

NOAA’s model forecasts near-surface smoke peaking at 1 µg/m³ around Sun, 12:00 AM 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.
