The initial frontal wave will push eastward into the panhandle with the northeast gulf coast seeing showers late tonight and highest snow accumulations expected along the outer coast with orographic enhancement. For most areas, snow is expected to be light and fluffy in nature due to cold temperatures both aloft and down to the surface. * WHAT...Heavy snow expected. Total snow accumulations of 5 to 9 inches. * WHERE...Prince of Wales Island. * WHEN...From noon Thursday to 9 AM AKST Friday. * IMPACTS...Travel will be very difficult. * ADDITIONAL DETAILS...Snow showers will gradually spread over the area as a frontal band pushes inland Thursday.

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.
