FORECAST SUMMARY: Monday November 3rd, 2025, through Friday November 7th, 2025
PM-2.5:
PM-2.5 concentrations are expected to be in the Good (Green AQI) range.
FORECAST DISCUSSION:
The first full week of November will have quite a back-and-forth in terms of pressure systems as an active pattern is in store for us Michiganders this week. As we wake up this Monday morning, a cold front is drifting off to the east and bringing the showers currently over the lower peninsula with it. On the backside of this frontal boundary is a high-pressure system which will drift northwards, bringing warmer temperatures along for the ride. This will precede a warm front associated with a low-pressure system which will impact us on Wednesday and provide rain showers for much of the state. Like a pinball machine, we bounce back under high-pressure and clearing skies on Thursday before, yet another low-pressure and associated precipitation make a return for Friday which will see stronger winds and more rain compared to Wednesday.
Due to the back-and-forth pressure systems, along with changing wind directions, PM-2.5 concentrations are not expected to be an issue this week due to the consistent change in air mass. On some smoke models, though, there appears to be the faintest signature of wildfire smoke over the state on Wednesday, but nothing more than a few low-Moderate scattered in northern areas. Overall, PM-2.5 concentrations will remain Good.
EXTENDED FORECAST:
Northerly winds cool us down into the 40s and 30s for the weekend ahead. Air quality should remain in the Good range.
