FORECAST SUMMARY: Saturday, june 15 Through Sunday, june 16
OZONE: 8-Hour average Ozone concentrations will be trending Good (AQI Green) to Moderate (AQI Yellow) in most of the state.

FORECAST DISCUSSION:
Michigan is under a dome of high pressure as we entered the weekend. As we get on the back side of the high pressure cell during Sunday, we will fall under a southerly wind regime and a significant warmup for early next week.
Sunday will likely be a ramp-up day for much of the state with southeast winds becoming more southwesterly during the day. Dew points will start out in the comfortable 50-degree range increasing into the low 60’s by the end of the day. Most of the state should stay in the Moderate range through Sunday.
Monday is looking more concerning as we are seeing persistent southwest winds, higher dew points, hotter temperatures, and the potential for plenty of sun. This trend looks to persist into the work week with the concern for increasing levels of ozone as the week progresses.
EXTENDED FORECAST:
Air Quality could be Moderate to USG during the beginning of the upcoming work week.
