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 Kenyon right now. All Minnesota warnings.

The forecaster’s discussion

Written by Minnesota Pollution Control Agency for Rochester Area and filed with AirNow.

Southeasterly flow over the next few days may bring slightly higher amounts of ozone precursors into the region from Chicagoland, but relatively mild temperatures and scattered clouds should limit ozone formation and keep us safely within the Green AQI category. Recent precipitation and light winds should similarly limit particulate concentrations statewide.

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 Kenyon in satellite imagery today.

NOAA’s model forecasts no measurable smoke near the ground here over the next two days.

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.
