Its 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: Air quality will degrade from north to south on Friday as Canadian wildfire smoke pushes in ahead of a cold front. Unhealthy for Sensitive Groups (USG) AQI (Orange category) is expected for much of the state, with the potential to reach Unhealthy AQI (Red category). Areas to the southwest (mostly along the Mississippi River valley) will have the best chance to remain in Moderate AQI on Friday. The front will move into northeast Wisconsin Friday evening and begin clearing the air from northeast to southwest. However, this will also push smoke further south and west, and an additional Air Quality Advisory may be needed on Saturday for western areas if PM2.5 concentrations remain high enough.

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.
