Other Pollutants:
PM10 - 19 Good
The build up of fine particles, combined with the transport of additional pollution from southerly winds out ahead of a weak area of low pressure, will likely result in Yellow (moderate) AQI across roughly the western half of Minnesota plus the Twin Cities today (Sunday). The rest of the state is most likely to have Green (good) AQI today. Widespread above average temperatures are expected to continue through the upcoming work week, which will set the stage for increasing levels of fine particle pollution due to increased moisture from the melting snow pack. Yellow AQI is likely across much of the state from Monday through at least Thursday, as only weak weather systems with generally light wind result in poor afternoon mixing. Nocturnal inversions will further limit dispersion. Highest concentrations should be across western Minnesota Monday and Tuesday, where moderate to high-end Yellow AQI is currently forecast.
