PM-2.5:
PM-2.5 concentrations are expected to be in the Good to low-Moderate range.
FORECAST DISCUSSION:
We wrap up this work week cooler than when it started as a cold front and associated rain showers made their way through the state yesterday, Thursday. Residual clouds and a slight chance of a pop-up shower can be expected today, Friday, but overall, the majority of Michiganders should remain dry. Sunshine will return to kick off the weekend early Saturday and will continue to peek through the clouds throughout the day. This is due to a High-pressure system drifting in from the west later this evening and into Saturday evening. Surface temperatures will hang around the 50s for most of the state due to predominantly northerly winds from the High-pressure system. As we get into Sunday, a Low-pressure system along with a frontal boundary tries to make its way through the state from the south, but High-pressure lingering to the west should keep it at bay for mid to northern parts of the state. Rain should be expected for southern parts of the state on Sunday as the Low-pressure slowly lifts northwards Sunday morning. Similar to Sunday, Monday will have lingering showers as well, as the pressure system hangs around the Great Lakes until late Monday.
For air quality, the drop in temperatures and cloudy skies will keep Ozone concentrations in the Good range for the weekend ahead. Shifting winds will keep the PM-2.5 concentrations in the Good range for much of the weekend. However, today, Friday, may see low-Moderate concentrations in the more populated areas across the state.
EXTENDED FORECAST:
Temperatures increase as we get into next week. Air quality will remain in the Good to low-Moderate range.
