DESCRIPTION: * WHAT...The PM2.5 AQI is expected to reach the Unhealthy for Sensitive Groups level. * WHERE...All of central, east-central, north-central, and northeast Wisconsin. * WHEN...Through 6:00 AM CDT Saturday. * ADDITIONAL DETAILS...Air quality will degrade from north to south today 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 today. The front will move through northeast Wisconsin this 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.
INSTRUCTION: Sensitive groups: Make outdoor activities shorter and less intense. It is okay 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.

Next Topic: Cumulus Clouds
The final form taken by a growing cumulus cloud is the
cumulonimbus cloud, which is very tall and dense.
The tower of a cumulonimbus cloud can soar 23 km into the atmosphere, although
most commonly they stop growing at an altitude of 6 km.
Even small cumulonimbus clouds appear very large in comparison to other cloud types.
They can signal the approach of stormy weather, such as thunderstorms or blizzards.

Next Topic: Evaporation
Drizzle is precipitation in the form of water droplets which are
smaller than raindrops.
Drizzle is characterized by fine, gently falling droplets and typically does not
impact human habitation in a negative way. The exception to this is freezing drizzle,
a condition where drizzle freezes immediately upon reaching earth's surface.
Freezing drizzle is still less dangerous than freezing rain, but can
potentially result in hazardous road conditions.
