3/22/2021 Forecast Update
FORECAST SUMMARY:
Monday, March 22nd, 2021 through Monday, March 29th, 2021
PM-2.5: 24-hour average Fine Particulate concentrations will be a mixture of Good to Low Moderate Monday and Tuesday with mostly Good the remainder of the forecast period.
FORECAST DISCUSSION:
The positioning of a low-pressure trough over the Plaines states, as of Monday morning, will cause warm southern air to continue flowing into the state. That warm, moist southern air is not terribly dirty, but it will give us the best opportunity for Low Moderates during this forecast period until the associated cold front passes through on Wednesday.
The remainder of the work week will have spotty rain and mostly Good Air Quality as another system moves up and across Southeast Michigan Thursday night and Friday morning.
The weekend looks a bit cooler and continued clean with yet another system moving through on Sunday.
EXTENDED FORECAST:
Air Quality should be mostly Good going into the next work week.
