FORECAST SUMMARY: Tuesday, January 17, 2023, through Monday, January 23, 2023
PM-2.5:
24-hour average Fine Particulate concentrations are expected to be mostly Good with occasional Low Moderate through the forecast period.
FORECAST DISCUSSION:
The forecast period begins with mild temperatures born on southerly winds in advance of an approaching low pressure system. Air Quality is currently mostly Good with a scattering of Low Moderates. As that low pressure system moves northeast, Tuesday evening, winds will shift to a more northwesterly direction. Air Quality will become all Good, throughout the state, at that time.
The next system is not far behind. This stronger system will cause winds to shift to eastly by late Wednesday. Winds will be brisk, and Air Quality is expected to remain Good. The system will pass through Michigan late Thursday and strong northwest winds will settle in through Friday.
Winds will remain west to southwest for most of the weekend keeping temperatures cooler and Air Quality Good.
The models are showing the potential for another low pressure system tracking up through the Ohio Valley late in the weekend. If that prediction happens, we will see the same progression of easterly winds followed by northwesterly winds late Sunday into Monday. Air Quality should remain Good.
EXTENDED FORECAST:
Air Quality should be mostly Good to begin the next work week.
