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 Preston right now. All Texas warnings.

The forecaster’s discussion

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

Hot southerly breezes will continue to bring northward Saharan dust. Meanwhile, a lack of rain desiccates vegetation, leaves little water to evaporate, and allows incoming solar radiation to heat the surface very effectively. Therefore, very high fire danger persists, and any fires may produce locally unhealthy smoke. Sufficient moisture aloft, steady breezes, and diurnal cumulus convection in the afternoon will limit ozone to the moderate category. Meanwhile, monsoonal moisture will bring scattered rain showers to the Panhandle through the forecast period. Early next week, a cold front will spread isolated thunderstorms to the rest of the state, and temperatures will drop significantly but stay above normal. Afterward, easterly flow with moisture, clouds, and virga aloft will impede ozone formation, but a frontal inversion and episodic sunshine enhance ozone concentrations.

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 Preston in satellite imagery today (Sun, 7:00 AM CDT to Sun, 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 0.6 µg/m³ around Sat, 10:00 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.
