FORECAST SUMMARY:

Monday April 18th, 2022, through Monday April 25th, 2022

OZONE: 8-hour average Ozone concentrations are expected to be mostly Good through the forecast period with a possibility of Low Moderates during the weekend.

PM-2.5:  24-hour average Fine Particulate concentrations are expected to be mostly Good early in the week with a mix of Good and Moderates for the remaining forecast period.

FORECAST DISCUSSION

The week starts in the Good Air Quality range complete with snow showers and a reminder that winter is not ready to release its hold on Michigan. 

We get back into a southerly air flow on Wednesday, with southeasterly winds.  This may push Southeast Michigan into the Low Moderate category for fine particulates.  Southwesterly winds, by Thursday, could put Southwest Michigan into Low Moderates.

The most interesting feature of the week occurs during Saturday when the State falls into the warm air sector of an advancing frontal system.  Temperatures could easily fall into the mid or upper 70’s with southwesterly winds.  Winds should be brisk enough to keep the atmosphere well mixed, but it is possible to see Moderates, for both ozone and fine particulates.  A good day for getting early yard work done.

A front should pass on Sunday or Monday ending the warmer temperatures and we will likely see maximum temperatures around 40, by Tuesday of next week.

EXTENDED FORECAST:

Air Quality is expected to be Good to Low Moderates starting the next work week.
