Forecast Discussion:
Calm, stable conditions over the area continue to allow particulate levels to increase during the morning and evening hours. This has resulted in PM10 in the mid Moderate AQI range, and PM2.5 in the upper Moderate AQI range. Looking ahead, today will likely have the highest particulate levels of the forecast period due to more fireplace usage as we head into the weekend. PM10 levels are forecast to remain elevated over the weekend, then drop down a bit on Monday with less fireplace activity. PM10 on the other hand, will likely increase a little on Monday with more dust-generating work activities.The exciting part of the forecast isn't until the middle of next week. We are forecasting a low pressure system to move through the region next Tuesday and Wednesday. With this weather system there is potential to get some much needed rain! We still anticipate elevated particulate levels early Tuesday, but with rain moving in later on Tuesday, particulate levels should plummet. Also worth noting, we may see somewhat elevated PM10 levels before the rain due to some breezy winds with the weather system moving in. However, due to the rain, we expect PM10 and PM2.5 to fall into the low Moderates on Tuesday, then the Good range on Wednesday.
Have a great weekend!
