FORECAST DISCUSSION:
The chill of Fall has slowly set in the past week or so with a further decrease in temperatures expected this week, but some slight increases as we approach the weekend.
Much needed rain fell across the state this past weekend with some residual showers early this morning. The remnants of the cold front and associated rain that came through will completely move out of the area later today, with northerly winds and cooler temperatures filling in behind it. There is a chance of pop-up lake effect rain showers in the beginning half of this week, but the majority of Michigan will remain dry and in the upper-40s to mid-50s temperature range. As we get into Wednesday, winds shift to a more southwesterly direction, which will cut off any remaining lake-effect rain showers while also increasing surface temperatures across the state. Into Thursday, High-pressure sets up to our east and will stay there into the weekend, providing us warmer temperatures and clear skies.
For air quality, Ozone will be in the Good range as we enter the middle of October and nearing the end of the annual Ozone season. This past weekend saw light, elevated wildfire smoke with some of it still hanging around this Monday morning, Throughout the beginning part of this week, this residual smoke will move out of the region with clear skies moving in behind it. There are still fires burning in west Canada and western US states, but smoke associated with those fires are not expected to impact our upper-levels or surface PM-2.5 concentrations as Good to low-Moderate concentrations are expected.
EXTENDED FORECAST:
The upcoming weekend looks to be yet another picturesque Michigan Fall weekend with sunny skies and temperatures in the 60s and 70s.
