FORECAST SUMMARY:

Saturday, June 5th, 2021 through Sunday, June 6th, 2021 

OZONE: 8-Hour average Ozone concentrations are expected to range from Moderate to USG. 

PM-2.5: 24-hour average Fine Particulate concentrations will be in the upper Good to middle Moderate range.

FORECAST DISCUSSION:

The forecast is on track as expected with sunny skies, warm temperatures, and strong west to southwest winds. The only exception is a frontal boundary bringing some clouds and precipitation to the upper peninsula and extreme northern lower peninsula.

Ozone ranged from Moderate to USG Friday across the state and readings in that range are still expected Saturday. This coincides with the current Air Quality Action Day we have in place. Since the forecast does not change as we move into Sunday, we are keeping the Air Quality Action Day in place through Sunday for both west and southeast Michigan. Forecast models show chances for precipitation as early as Monday. Forecast maps will be evaluated Sunday morning and this forecast will be updated to determine if the Action Day needs to be extended.

Fine particulate readings are in the upper Good to low Moderate range, and levels in that range will continue through the weekend.

EXTENDED FORECAST:

Extended forecast models are hinting at chances for storms Monday/Tuesday of next week. Until weather conditions change, we will be doing daily updates of the air quality forecast.
