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 Bloomfield right now. All Kentucky warnings.

The forecaster’s discussion
Written by Louisville Metro Air Pollution Control District for Louisville and filed with AirNow.
Southern Regions: PM2.5 was good Friday through Sunday, and ozone was good for all for the forecast period except for one moderate in Louisville on Saturday. Current hourly readings this morning are good for ozone with PM2.5 a mix of good and moderate around Louisville. Temperatures are forecast to be slightly cooler Monday with overnight low's in the mid 50'sand daytime highs in the upper 70's. Temperatures are then forecast to rise to be above average for Tuesday (low 80's) and Wednesday (low 90's). There is ample mixing present in the boundary layer leading to a large temperature gradient across the state. The models have underdone mixing leading to the likelihood that temperatures will actually exceed model guidance the next few days. Light surface winds are expected from the high pressure. Winds Monday are forecast to be N 0-10 MPH, calm Tuesday, and S 0-10 MPH Wednesday. Southerly flow is forecast return to the region Wednesday because the surface high pressure moves more to the east. The NOAA 06Z BC model for PM2.5 forecasts good levels for SW Monday through Wednesday and good for SE Monday with moderate possible Tuesday and Wednesday. The Canadian model shows good levels for that entire forecast period. I think good is likely for Monday with a mix of good and low-end moderate possible Tuesday and Wednesday due to low wind speeds and a stagnant air mass, I do think if mixing is higher than forecast, levels will stay mostly to entirely good. The NOAA 06Z BC model for ozone predicts good levels for Monday and Tuesday with moderate likely Wednesday. The Canadian model forecasts good levels Monday, with moderate possible Tuesday and Wednesday. Good seems likely today and tomorrow with the cooler temperatures and wind direction, but moderate is possible Wednesday as the flow switches to be southerly, temperatures are in the 90's and RH values are low. Mixing heights are forecast to be around 6,000 ft. Monday and Tuesday.

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.
