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.

A shelf cloud is similar to a wall cloud, but forms at the front
of a storm cloud, instead of at the rear, where wall clouds form.
A shelf cloud is caused by a series of events set into motion by the advancing
storm; first, cool air settles along the ground where precipitation has just fallen.
As the cool air is brought in, the warmer air is displaced, and rises above it,
because it is less dense. When the warmer air reaches the bottom of the storm cloud,
it begins to cool again, and the resulting condensation is a visible shelf cloud.

Snow is precipitation taking the form of ice crystals. Each ice crystal, or snowflake,
has unique characteristics, but all of them grow in a hexagonal structure.
Snowfall can last for sustained periods of time and result in significant buildup
of snow on the ground.
On the earth's surface, snow starts out light and powdery, but as it begins to melt
it tends to become more granular, producing small bits of ice which have the consistency of
sand. After several cycles of melting and freezing, snow can become very dense
and ice-like, commonly known as snow pack.
