FORECAST DISCUSSION
Despite a clean background for most of the week, Thursday’s Air Quality was a rocky road with the majority of the state’s monitors unexpectedly crossing into the USG range. Seeing the numbers climbing early in the day, ADQ did upgrade the forecast along the western lakeshore and Detroit area to USG although it was too late to issue an effective Action Day Alert.
Fortunately, that was a one-day event as clouds and showers move in along the lakeshore Friday morning and slowly expand eastward through the day. Severe weather does not look to be an issue, but potential rainfall amounts could reach an inch or better in some areas.
That said, the predicted rain stops late Saturday morning, and clouds clear out in Southwest Michigan for the afternoon. It is unsure how much of a clean out we will get from the rain and a gradual wind shift from west to northwest, so I tend to review the conditions Saturday morning and update the forecast, at that time.
EXTENDED FORECAST:
Air Quality is expected to be Good to Moderate for the remainder of the weekend.
