2/6/2023 Forecast Update

FORECAST SUMMARY: Monday, February 6th, 2023, through Monday, February 13th, 2023

PM-2.5:
24-hour average Fine Particulate concentrations are expected to be mostly Good with occasional Low Moderate during mid-week.

FORECAST DISCUSSION:

High pressure over the upper Midwest will slide eastward during Monday with Air Quality mostly Good.  In its wake, a cold front will advance with strong southerly winds and warming temperatures for late Monday night and early Tuesday.  That front is projected to pass through Michigan during the day Tuesday. 

 High pressure will return for the remainder of Tuesday and Wednesday.  The best chance for any Low Moderate conditions, during the forecast period, would likely be Wednesday with light southerly winds allowing a buildup of fine particulates.

 A stronger low pressure system invades the area during early Thursday providing a decent amount of mixed precipitation.  As that system exits the area late Thursday, winds will shift to the northwest and any residual fine particulates should be cleaned out returning the state to the Good category.

 Winds are expected to return to a southerly flow during Sunday and Monday.  Winds speeds are expected to be fairly brisk and should keep the atmosphere well mixed.  Most of the state is expected to have Good Air Quality but the occasional Low Moderate could sneak in.

EXTENDED FORECAST:

Air Quality should be mostly Good to begin the next work week.
