12/13/2021 Forecast Update
FORECAST SUMMARY:
FORECAST SUMMARY: Monday, December 13th, 2021 through Friday, December 17th, 2021
PM-2.5: 24-hour average Fine Particulate levels will range between Good and middle Moderate through the forecast period.
FORECAST DISCUSSION:
Quiet weather conditions are in store early this week along with warmer than normal temperatures. Dry conditions remain Monday and most of Tuesday, but as moisture increases into Wednesday so will the chance for precipitation. Warmer temperatures decrease Thursday behind a cold front and very strong winds may again be possible across parts of the state.
As for air quality, strong winds from the weekend kept fine particulate levels Good and a continuation of Good reading is expected Monday. As temperatures and moisture increase towards mid-week, fine particulate levels also increase into the Moderate range. Winds behind the Thursday cold front will bring fine particulate back to Good for the end of the workweek.
EXTENDED FORECAST:
Some uncertainty exists in the extended models, but it looks like the Thursday front stalls south across Indiana/Ohio with a system developing along the boundary for the weekend. It is unclear whether the track of this system will move into the Great Lakes region or not. While fine particulate higher than Moderate is not expected during the weekend or early next week, this forecast will be updated Friday to better detail fine particulate in the forecast period.
