Weather Alert in Michigan
Air Quality Alert issued July 31 at 4:12PM 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 issued an Air Quality Advisory for elevated levels of fine particulate (PM2.5) across the state of Michigan. Pollutants across the state are expected to be in the Unhealthy for Sensitive Groups (USG, Orange AQI) range with some locations reaching the Unhealthy (Red AQI) range. The Air Quality Advisory includes all Michigan counties. Smoke from Canadian wildfires remains over the state Thursday, with PM2.5 concentrations ranging from USG to Unhealthy. Some locations, mostly in the Lower Peninsula, may experience improvements in air quality from late Thursday into Friday, however, that is expected to be short-lived as additional smoke plumes drop into the region. High pressure settling overhead will limit dispersion and keep smoke at the surface through the end of the week. This sustains the threat of increased PM2.5 and readings in the USG range will continue through Saturday, with some locations reaching the Unhealthy 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.

A nimbostratus cloud is similar to a stratus cloud in its formless,
smooth appearance. However, a nimbostratus cloud is darker than a stratus cloud,
because it is thicker.
Unlike a stratus cloud, a nimbostratus cloud typically brings with it the threat
of moderate to heavy precipitation. In some cases, the precipitation may evaporate
before reaching the ground, a phenomenon known as virga.

Precipitation in the form of water droplets is called rain.
Rain generally has a tendency to fall with less intensity over a greater period
of time, and when rainfall is more severe it is usually less sustained.
Rain is the most common form of precipitation and happens with greater frequency
depending on the season and regional influences. Cities have been shown to have
an observable effect on rainfall, due to an effect called the urban heat island.
Compared to upwind, monthly rainfall between twenty and forty miles downwind of
cities is 30% greater.
