FORECAST SUMMARY:

FORECAST SUMMARY: Monday, January 10th, 2022, through Tuesday, January 18th, 2022

PM-2.5:  24-hour average Fine Particulate concentrations are expected to be mostly Good with only a few scattered Low Moderates early to mid-week.

FORECAST DISCUSSION:

After more moderate temperatures during the weekend, a shot of arctic air is providing a chilly start to the forecast week.  Air Quality readings are Good, throughout the state, as we start the workweek.

High pressure will slide across the Ohio Valley, during Tuesday, and switch us back to brisk southerly winds and a brief warming trend.  With that warming trend, we run the risk of an increase in Fine Particulates in some areas of the State, primarily the Southwest and Southeast corners of Michigan.  But that increase would be small, and we would only see Low Moderates, at the worst.

The early week models are following a short wave of energy currently forecast to track across the Upper Midwest/Great Lakes late Wednesday into Thursday along with the southern progress of a cold front sinking south from the northern Great Lakes area.  It does not appear to have the makings of a major storm, but some light snow may accompany this system.  Winds will shift to the northwest providing another cleaning shot of colder air.

 A stronger system is being suggested by the models for the early weekend.  While the jury is still out on the strength and track of this system, overall predicted wind patterns should keep our Air Quality Good.

Note that since the MLK holiday is Monday, January 17, this forecast will be updated on Tuesday, January 18.
