Weather Alert in Michigan
Air Quality Alert issued July 12 at 10:15AM EDT by NWS Northern Indiana
AREAS AFFECTED: Cass; St. Joseph; Branch; Hillsdale; Northern Berrien; Southern Berrien
DESCRIPTION: The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has declared an Air Quality Alert starting midnight tonight through Noon EDT Monday, July 14th, for elevated levels of fine particulate (PM2.5) in parts of southwest Michigan. Pollutants within those areas are expected to be in the USG to Unhealthy (Orange and Red AQI) range. The Air Quality Alert is in effect for the following counties in southwest Michigan... Berrien, Cass, St Joseph, Branch, and Hillsdale Wildfire smoke from Canada will push into Michigan from Saturday to Monday. Increased fine particulate levels will reach the western portion of the Upper Peninsula on Saturday afternoon. The smoke will push east and south, expanding across the rest of the state as Sunday progresses. Highest concentrations will be seen in northern parts of the state, but southwest Michigan can expect levels of fine particulate in the Moderate to USG range. It is recommended that, when possible, you avoid strenuous outdoor activities, especially those with heart disease and respiratory diseases like asthma. Monitor for symptoms such as wheezing, coughing, chest tightness, dizziness, or burning in nose, throat, and eyes. Reduce or eliminate activities that contribute to air pollution, such as: * outdoor burning, * use of residential wood burning devices. Tips for households: Keep windows closed overnight to prevent smoke from getting indoors and, if possible, run central air conditioning with MERV-13 or higher rated filters.

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.

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.
