FORECAST SUMMARY: Friday, August 16, 2024, through Monday, August 19, 2024
OZONE:
8-Hour average Ozone concentrations will be mostly Good (AQI Green).
PM-2.5:
24-hour average Fine Particulate concentrations are also expected to be Good (AQI Green) to Moderate (AQI Yellow).
FORECAST DISCUSSION:
Low pressure over northwest WI and an upper low is sending minor short waves of low pressure eastward towards Michigan. That will keep the weekend mostly wet and cool.
The rain should end Sunday evening as the low pressure systems migrates eastward. Clearer weather is expected, early next week, with unseasonably cooler weather as northwest winds bring in cooler air.
Ozone concentrations will certainly be Good during this time period. However, we are keeping a close eye on wildfire smoke out west as the models are showing Minnesota and Wisconsin potentially receiving some surface smoke. The models are also indicating some surface smoke may reach Michigan, later in the weekend, but concentrations only reaching the Moderate range. While I do not anticipate anything worse than Moderate, we will keep a close eye on the situation and update this forecast should anything change.
EXTENDED FORECAST:
Air Quality is expected to be Good to Moderate going into the upcoming work week.
