The highest AQ index in Michigan (as of 3:00 EST) is currently the Southeast area. Particle Pollution (PM2.5) is measuring at 57 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Particle Pollution (PM2.5) will be in the Bay Area-Thumb Area area. It is forecasted to be Good, meaning air quality is satisfactory, and air pollution poses little or no risk.
Cold air advection will continue today, Friday, as an upper-level low lingers over the eastern Great Lakes. A north to northeasterly flow combined with cooler air will support lake effect precipitation, with a few snowflakes occasionally mixing in across northern areas. High pressure builds in on Saturday, keeping conditions dry across southern portions of the region through the weekend. However, a passing shortwave may bring light precipitation to northern areas on Sunday. Friday will be the coldest day of the forecast period. Temperatures will gradually recover, with highs returning to the 50s across southern areas by Saturday and expanding northward by Sunday into Monday. Predominantly north to northwesterly flow throughout the forecast period is expected to keep fine particulate concentrations in the Good range.
