FORECAST SUMMARY: Monday, August 5, 2024, through Friday, August 9, 2024
OZONE:
8-Hour average Ozone concentrations will be mostly Good (AQI Green).
PM-2.5:
24-hour average Fine Particulate concentrations are expected to be mostly Moderate (AQI Yellow), early in the week, transitioning to Good (AQI Green) for the latter half of the week
Monday and Tuesday look to be the most active weather for the week, followed by cooler, drier weather for the remain of the week and weekend. As of Monday morning, a cold front is draped across the southern portion of the state and will gradually drop south during the day. A moisture rich atmosphere will provide the opportunity for locally heavy rainfall amounts along the frontal boundary during Monday.
More widespread rainfall is likely for late tonight into Tuesday as the front stalls below the Michigan/Indiana/Ohio border. A wave of low pressure is projected to ride along the boundary and into the Michigan area early Tuesday morning. Severe weather looks unlikely, but we could see rainfall amounts in the 1”-3” range before it exits the region late Tuesday.
Any threat of elevated ozone is non-existent during this period. PM-2.5 values have been hovering in the Moderate range thanks to a small amount of elevated wildfire smoke mixing down from above but will gradually clear out.
Surface high pressure will dominate our weather for most of the time Tuesday night through Sunday. This will provide cooler temperatures and drier humidity along with clear skies. Daytime high temperatures will struggle to get past the 80-degree mark and nights will be comfortably cool with temperatures in the upper 50’s. Air Quality is expected to be Good for that portion of the forecast period and into the weekend.
EXTENDED FORECAST:
Air Quality is expected to be Good going into the upcoming weekend.
