FORECAST SUMMARY:
Monday, March 15th, 2021 through Monday, March 22nd, 2021
PM-2.5: 24-hour average Fine Particulate concentrations will be mostly Good with the best chance of Low Moderates during Wednesday and late weekend.
FORECAST DISCUSSION:
A low pressure system will make its way across the Ohio Valley during the Monday and Tuesday time frame yielding easterly winds across Michigan. While some precipitation in the form of rain, snow, and freezing drizzle may accompany this system as it passes to our south, Air Quality should remain mostly Good.
The best chance of any Moderate concentrations, this week, will likely be Wednesday as winds become calm and variable and some localized stagnation could occur.
A similar but stronger low pressure system is projected to follow the same track Thursday and Friday. Brisk, clean northeasterly winds and Good Air Quality will prevail during this time to wrap up the work week.
Warmer southerly winds return by Sunday with a chance of increasing fine particulates for the beginning of the next work week.
EXTENDED FORECAST:
Air Quality should be mostly Good to Low Moderate going into the next work week.
