FORECAST SUMMARY:
Sunday, June 6th, 2021 through Monday, June 7th, 2021
OZONE: 8-Hour average Ozone concentrations are expected to range from Moderate to USG Sunday and Good to Moderate Monday.
PM-2.5: 24-hour average Fine Particulate concentrations will be in the Good to low Moderate range.
FORECAST DISCUSSION:
Sunny skies and warm temperatures can be expected today. Ozone levels on Saturday ranged from Moderate to high USG with most USG readings in the west and southeast Michigan. The threat for increased ozone continues today and we have an Air Quality Action Day in place to cover this threat. An upper-level system moves in from the south, late Sunday into Monday. This system brings clouds, moisture, and chances for scattered, heavy rain. While warm temperatures continue, ozone concentrations should finally decrease; therefore, we will not continue the Air Quality Action Day into Monday.
Strong winds the past few days have helped keep fine particulate readings in check. Levels Sunday and Monday are not expected to reach higher than low Moderate.
EXTENDED FORECAST:
Extended forecast models show the upper system lingering over the state for most of the week. This would keep clouds and precipitation chances in the forecast, and with this, air pollution levels should not increase significantly.
