FORECAST SUMMARY:
Tuesday, June 30th, 2020 through Wednesday, July 1st, 2020
OZONE: 8-hour average Ozone concentrations will be mostly Moderate Tuesday and Wednesday. Air Quality will likely decrease past mid-week.
PM-2.5: 24-hour average Fine Particulate concentrations will range from Good to Low Moderate through the week.
FORECAST DISCUSSION:
A warm, dry forecast remains as we continue into the week. Ozone levels Monday ranged from Good to middle Moderate across the state. Those readings were an increase from Sunday, but forecast models are showing no higher than Moderate ozone through Wednesday. Considering that, and the fact levels Tuesday morning are the same or a bit lower than the same time Monday, we are keeping with a Moderate ozone forecast through Wednesday. There is still a small chance for a monitor or two to reach USG, but we feel this would be an isolated event. As was stated yesterday, with east/southeast winds, the area with the highest potential will be west/northwest of the Detroit area and/or along the immediate West Michigan lakeshore.
Without a change in airmass this week we anticipate ozone to continue a slow climb over the next few days. Also, given the fact that we are in the period of the summer when ozone production potential is at its highest, we will be watching closely the entire week.
With the expected forecast, fine particulate will range from upper Good to low Moderate.
EXTENDED FORECAST:
Air Quality will likely elevate to Moderate and perhaps USG during the latter half of the week.
