FORECAST SUMMARY:
Monday, May 18th, 2020 through Monday, May 25th, 2020

FORECAST DISCUSSION
The low pressure system that has dumped a couple inches of rain across the state over the last two days will continue to affect our wind pattern for most of the work week. The counterclockwise circulation around the low, currently located over Illinois, is providing easterly winds and Good Air Quality.
The slow-moving nature of this system will have it migrating southeastward over the next few days. This will keep our winds with an easterly component and should keep our Air Quality in the Good category with some scattered Low Moderates west of the Detroit area.
The next change in the wind pattern, which could impact Air Quality, will not be seen until the weekend when winds turn calm before turning southwest in advance of the next low pressure system. At that time, we may see some Low Moderates in fine particulates but should not significantly affect ozone concentrations.
EXTENDED FORECAST:
Air Quality should remain mostly Good with some scattered Low Moderates going into the next work week.
