PM-2.5: 24-hour average Fine Particulate concentrations will be a mixture of Good and Low Moderate.
FORECAST DISCUSSION
Monday will likely be the nicest day of the week before active weather moves through and drops temperatures to below-average levels. Monday’s sun and warmer temperatures will end as a cold front drops down and passes through Monday night. The colder air behind the front will provide Good Air Quality for the region.
Very cold air, Tuesday night, will give way to slightly warmer air during Wednesday and Thursday as a warm front migrates northward and stalls over the Michigan/Indiana border. The air north of the front will still be cold enough to support snow showers and the placement of that stalled warm front will likely lead to some Low Moderates along the lake shore and Southeast Michigan areas.
By the weekend, that front should drop southward as a cold front and return the area back to solid Good levels which should persist through Sunday.
EXTENDED FORECAST:
Air Quality should be mostly Good going into the next work week.
