PM-2.5:

FORECAST DISCUSSION:
High-pressure and clear skies round off the work week and kickoff the weekend for us Michiganders. Many of us will approach the 50-degree mark today, Friday, while others stay in the low-to-mid 40s. As we get into Saturday, the High-pressure system moves right over top of us providing ample sunlight and minimal clouds with surface temperatures well into the 50s throughout the state. These warming temperatures will be provided by southwesterly winds as they wrap around the High-pressure system before it moves off the to the east come Sunday. An encroaching Low-pressure system somewhat spoils the weekend fun with potential spotty rain expected on Sunday, but temperatures remain in the 50s, however. The Low-pressure system continues to move eastward throughout Sunday and into Monday as even warmer temperatures are expected Monday to kick off the next week.
While winds stay more stagnant today, PM-2.5 concentrations are expected to remain in the Good to low-Moderate range. Shifting winds tomorrow will help decrease and keep these concentrations at bay for the time being. As winds shift to a more southerly direction, particulate from the south may increase concentrations to the low-Moderate range for much of Sunday and into Monday. For Ozone, like a broken record, it is still not warm enough for any real Ozone development this weekend. As temperatures warm into the 60s on Monday, however, we may see a few monitors eclipse the Moderate range for an hour or so, especially in more populated areas.
EXTENDED FORECAST:
The aforementioned Low-pressure system will bring a cold front along with it which will cool down temperatures for Tuesday, but we quickly rebound come midweek. Air quality should reman in the Good range.
