FORECAST SUMMARY:
Monday, March 9th, 2020 through Monday, March 16th, 2020
PM-2.5: 24-hour average Fine Particulate concentrations will a mixture of Good and Low Moderate.
FORECAST DISCUSSION
A low pressure system will pass through Michigan, Monday night, and provide a bit of rain followed by cleaner northwest winds during Tuesday.
Winds will taper off during Wednesday and swing around to the southeast providing an opportunity for fine particulate numbers to start creeping back into the Low Moderate range especially along the lake shore and southeast Michigan. Those concentrations will likely amplify a bit during Thursday as those winds become more moist and warmer under a solid southwest flow. I expect most of the state will experience Low/Mid-Moderate concentrations during Thursday.
Another system is expected to pass through late Thursday which should return our Air Quality back into the Good range. I expect those Good conditions to persist through the weekend, even as winds turn to the northeast during Sunday and Monday.
EXTENDED FORECAST:
Air Quality should be mostly Good going into the next work week.
