FORECAST SUMMARY: Monday, November 17, 2025 through Friday, November 21, 2025
PM-2.5: 24-hour average Fine Particulate concentrations are expected to be mostly Good (AQI Green) to scattered Low Moderate (AQI Yellow).
FORECAST DISCUSSION:
A low-pressure system, currently in the central Plaine states, as of Monday morning, will migrate eastward and impact our weather into midweek. The system will pass to our south, with a warm front stretching across the Ohio Valley. As the warmer air to our south overrides the colder air at the surface, we can expect some precipitation to form in the southern half of the Lower Peninsula late Monday night through most of Tuesday. Drier air at the surface will evaporate much of the early precipitation, but as the air becomes more saturated, precipitation will eventually reach the surface. The first precipitation to reach the ground will likely be snow, which will transition to sleet and rain as daytime temperatures warm. The potential for some lingering drizzle/freezing drizzle could last into Tuesday evening.
The next chance for some precipitation occurs Thursday into Friday morning, when we will likely see some rain, thanks to a northern trough moving through the region. Current model projections indicate the weekend should be dry.
Air Quality should not be an issue as fine particulate matter levels stays Good with a few scattered Low Moderates.
EXTENDED FORECAST:
Air Quality is expected to remain Good to Low Moderate entering the upcoming weekend.
