The highest AQ index in Michigan (as of 12:00 EDT) is currently the Detroit area. Particle Pollution (PM2.5) is measuring at 57 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Ozone (OZONE) will be in the Ann Arbor area. It is forecasted to be Good, meaning air quality is satisfactory, and air pollution poses little or no risk.
The week begins with Good Air Quality throughout the state, and the trend should continue through the majority of the work week. The quiet, tranquil weather we see Monday morning should persist into Tuesday morning with the potential for severe weather Tuesday evening into Tuesday night. The Storm Prediction Center has increased our chance of severe weather bumping the threat from a marginal to a slight chance. Locally heavy rain looks more than possible from Tuesday afternoon through Wednesday. We are likely looking at swaths of one to possibly two inches of rain especially from I-96 to the south. Rivers are higher now given recent rains so additional precipitation will likely push quite a few river basin locations to near flood stage. This is Michigan and just because March has arrived does not mean winter is over. A potent clipper system is expected to sweep from west to east through the area Thursday night into Friday. Accumulating snow is potentially expected across Central Lower Michigan with this system, albeit warming surface conditions should keep it to a minimum. A preview of the weekend shows seasonable temperatures in the lower 40’s with a chance of rain/snow shower activity. EXTENDED FORECAST: Air Quality is expected to continue to be mostly Good entering the upcoming weekend.
