Everyone else: Keep outdoor activities shorter and less intense. Go inside if you have symptoms. Additional Details: Canadian wildfire smoke will continue to impact Wisconsin`s surface air quality over the next several days. Conditions have improved since Thursday as a pocket of cleaner air has infiltrated the widespread blanket of dense smoke across eastern Wisconsin. However, a mix of Unhealthy for Sensitive Groups (USG; Orange) AQI and Unhealthy (Red) AQI is still expected today, with locations farther north more likely to see heavier smoke. Continued gradual improvement is currently anticipated heading into the weekend, but USG (Orange) AQI to Unhealthy (Red) AQI will remain possible. Conditions will continue to be reevaluated on a day-to-day basis, including updates to the forecast and any associated Air Quality Advisories.

Weather Topic: What are Stratus Clouds?

Stratus Clouds Next Topic: Wall Clouds

Stratus clouds are similar to altostratus clouds, but form at a lower altitude and are identified by their fog-like appearance, lacking the distinguishing features of most clouds.

Stratus clouds are wider than most clouds, and their base has a smooth, uniform look which is lighter in color than a nimbostratus cloud. The presence of a stratus cloud indicates the possibility of minor precipitation, such as drizzle, but heavier precipitation does not typically arrive in the form of a stratus cloud.

Altocumulus Clouds Next Topic: Altostratus Clouds

Similar to cirrocumulus clouds, altocumulus clouds are characterized by cloud patches. They are distinguished by larger cloudlets than cirrocumulus clouds but are still smaller than stratocumulus clouds.

Altocumulus clouds most commonly form in middle altitudes (between 2 and 5 km) and may resemble, at times, the shape of a flying saucer. These uncommon formations, called altocumulus lenticularis, are created by uplift in the atmosphere and are most often seen in close proximity to mountains.
