11/29/2021 Forecast Update
FORECAST SUMMARY:
Monday November 29th, 2021, through Monday December 6th, 2021
PM-2.5: 24-hour average Fine Particulate concentrations are expected to be mostly Good with only a few scattered Moderates during mid-week
FORECAST DISCUSSION
The early half of the week looks to be more active than the latter half. An upper wave of low pressure will cut across the Great Lakes today and tonight. With dry air in place, initial precipitation is expected to evaporate before it hits the ground. By tonight, the air should be saturated enough to provide 1” to 2” of fresh snow. I am expecting Air Quality to remain mostly Good through Monday and Tuesday.
Wednesday may be the best chance to see some scattered Moderates throughout Michigan. Warming temperatures and southern winds will cause some snow melt which could add enough moisture to the atmosphere to trigger a very slight increase in Fine Particulates. That said, I believe most of the forecast area will remain Good with only a few Low Moderates.
The remainder of the forecast period looks to have favorable winds for Good Air Quality with no long-range predicted precipitation events to cause concern.
EXTENDED FORECAST:
Air Quality is expected to be mostly Good to start the next work week.
