The highest AQ index in Michigan (as of 7:00 EDT) is currently the Detroit area. Particle Pollution (PM2.5) is measuring at 65 (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 Ozone (OZONE) will be in the Ann Arbor area. It is forecasted to be Good, meaning air quality is satisfactory, and air pollution poses little or no risk.
FORECAST DISCUSSION: The first full week of May has come and gone with below average temperatures, but drier conditions compared to recent weeks. The weekend ahead will see a continuation of the current weather regime with slightly warmer temperatures on Saturday for the lower peninsula. For the upper peninsula, a cold front will be making its way through the state this weekend, impacting northern areas first, so cooler temperatures are expected in those areas. With this cold front, winds will be mostly northerly in the upper peninsula, hence the cooler temperatures, while westerly winds will be over the lower peninsula, allowing for temperatures to reach the 60s. Into Sunday morning, the aforementioned front will cross over the entire state, shifting winds to predominantly northerly which will cool off all Michiganders. Pop up rain showers should be expected throughout Saturday afternoon as well with Sunday clear of any rain showers. Monday looks to be almost a copy and paste of Sunday with temperatures in the upper-40s to mid-50s and clear skies. For air quality, Ozone continues to be a non-issue due to cooler temperatures. For fine particulate matter, northerly flow in the latter half of the weekend will clean out any residual Moderate concentrations that occur. Any Moderate concentration that pop ups will be in the low-Moderate range due to shifting winds, lack of localized wildfire smoke, and relatively clean air. EXTENDED FORECAST: A temperature increase is on the horizon starting mid-next week. Air quality looks to remain in the Good range for the majority of next week.
