Weather Alert in Michigan
Air Quality Alert issued June 22 at 11:12AM EDT by NWS Northern Indiana
AREAS AFFECTED: Cass; Northern Berrien; Southern Berrien
DESCRIPTION: The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has declared an Air Quality Advisory through for June 22 and June 23, for elevated levels of ozone in western counties in Michigan. Pollutants within those areas are expected to be in the Unhealthy for Sensitive Groups (USG, Orange AQI) range. The Air Quality Advisory is in effect for the following counties in southwest Michigan... Berrien and Cass We are in the peak of ozone season, and the current forecast shows ozone-conducive conditions for Sunday and Monday. Surface temperatures in the 90s, coupled with ample sunshine and southwest winds, create an environment favorable for ozone development along the Lake Michigan shoreline. It is recommended that, when possible, you avoid strenuous outdoor activities, especially those with respiratory diseases such as asthma. People and businesses are urged to avoid activities which lead to ozone formation. These activities include: * refueling vehicles or topping off when refueling; * using gasoline powered lawn equipment; * using charcoal lighter fluid. Positive activities include: * driving less; * telecommuting; * walking or bike riding; * delaying or combining errands; * using water-based paints.

A fractus cloud (scud) is a fragmented, tattered cloud which has
likely been sheared off of another cloud. They are accessory clouds, meaning they
develop from parent clouds, and are named in a way which describes the original
cloud which contained them.
Fractus clouds which have originated from cumulus clouds are referred to as
cumulus fractus, while fractus clouds which have originated from stratus clouds
are referred to as stratus fractus. Under certain conditions a fractus cloud might
merge with another cloud, or develop into a cumulus cloud, but usually a
fractus cloud seen by itself will dissipate rapidly.
They are often observed on the leading and trailing edges of storm clouds,
and are a display of wind activity.

Weather Topic: What is Graupel?
Home - Education - Precipitation - Graupel
Next Topic: Hail
Graupel is a form of precipitation that is created by atmospheric conditions
which cause supercooled water droplets to contact snow crystals and freeze to
their surface.
Sometimes known as soft hail or snow pellets, graupel is delicate and easily
destroyed by touch. Whereas hail usually falls during severe weather, graupel
doesn't require such conditions to form, and can form in mild precipitation
similar to situations which produce snowfall.
