FORECAST DISCUSSION:
The past weekend was a bit busy in terms of forecasting elevated ozone. Mother Nature did share the pain throughout the state with West Michigan having the most impacted monitors on Friday, Southeast Michigan hit hardest on Saturday, and Seney in the U.P. was the lone high monitor on Sunday.
This week will still have temperatures in the mid-80’s but we should not see much in the way of elevated ozone. We can thank mostly overcast skies and frequent chances of precipitation to keep ozone levels in check for most of the work week. Fine particulates, however, could still reach the Moderate levels as sunlight is not necessary for the growth of PM-2.5 particulates.
Right now, the long-range forecast is showing a warm front boundary over Michigan on Saturday followed by a cold front passage on Sunday. This would clean out the atmosphere and start the next week in the Good category with cooler temperatures and less humidity. As such, the chances for any pollutants reaching the USG levels during this forecast period are low and the next forecast is scheduled for next Monday. Should conditions change we will update this forecast, as necessary.
EXTENDED FORECAST:
Air Quality should be mostly Good going into the next work week.
