WHEN...From 10 AM Monday until 3 PM Tuesday. Precautionary/Preparedness Actions: Sensitive groups: Make outdoor activities shorter and less intense. It is OK to be active outdoors but take more breaks. Watch for symptoms such as coughing or shortness of breath. People with asthma: Follow your asthma action plan and keep quick relief medicine handy. People with heart disease: Symptoms such as palpitations, shortness of breath, or unusual fatigue may indicate a serious problem. If you have any of these, contact your health care provider. Additional Details: Canadian wildfire smoke will impact surface air quality as it moves ENE across northern portions of the state through early Tuesday afternoon. The heaviest smoke impacts are expected in far northwest Wisconsin, where PM2.5 NowCast AQI values of Unhealthy (Red) will be possible. Lesser impacts in the Moderate (Yellow) to Unhealthy for Sensitive Groups (Orange) AQI range are expected further south and east in the advisory area. A cold front moving in from the northwest on Tuesday morning will begin to clear this initial round of smoke from northwest to southeast. Although more smoke could move in behind the front, we do not expect advisory criteria to be met with the second round of smoke at this time.

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.

Next Topic: Cirrostratus Clouds
Cirrocumulus clouds form at high altitudes (usually around 5 km)
and have distinguishing characteristics displayed in a fine layer of
small cloud patches. These small cloud patches are sometimes referred to as
"cloudlets" in relation to the whole cloud formation.
Cirrocumulus clouds are formed from ice crystals and water droplets. Often, the
water droplets in the cloud freeze into ice crystals and the cloud becomes a
cirrostratus cloud. Because of this common occurrence, cirrocumulus cloud
formations generally pass rapidly.
