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.

Altostratus clouds form at mid to high-level altitudes
(between 2 and 7 km) and are created by a warm, stable air mass which causes
water vapor
to condense as it rise through the atmosphere. Usually altostratus clouds are
featureless sheets characterized by a uniform color.
In some cases, wind punching through the cloud formation may give it a waved
appearance, called altostratus undulatus. Altostratus clouds
are commonly seen with other cloud formations accompanying them.

Next Topic: Cirrus Clouds
Cirrostratus clouds are high, thin clouds that form above
20,000 feet and are made mostly of ice crystals. They sometimes look like giant
feathers, horse tails, or curls of hair in the sky.
These clouds are pushed by the jet stream and can move at high speeds reaching
100 mph.
What do they indicate?
They indicate that a precipitation is likely within 24 hours.
