Snow will gradually end across the northern panhandle through Sunday afternoon with longer duration advisories continuing for portions of the far southern panhandle. Snowfall accumulations will be variable across the area due to the hit or miss nature of these showers. Rates as high as 1 inch per hour and visibilities down to 1 mile or less will be possible within any heavier showers that repeatedly move over the same location. For the southern panhandle communities, temperatures are expected to start cooling through Sunday with bands of snow moving through the southern and central panhandle by the afternoon into Sunday night, prompting the longer duration Winter Weather Advisory. Accumulations in the south will be the highest on the higher elevations of Prince of Wales Island midday Sunday, but more accumulations expected at sea level by Sunday evening and night as temperatures cool through Sunday evening. * WHAT...Snow. Total snow accumulations of 2 to 5 inches.

A contrail is an artificial cloud, created by the passing of an
aircraft.
Contrails form because water vapor in the exhaust of aircraft engines is suspended
in the air under certain temperatures and humidity conditions. These contrails
are called exhaust contrails.
Another type of contrail can form due to a temporary reduction in air pressure
moving over the plane's surface, causing condensation.
These are called aerodynamic contrails.
When you can see your breath on a cold day, it is also because of condensation.
The reason contrails last longer than the condensation from your breath is
because the water in contrails freezes into ice particles.

Cumulus clouds are fluffy and textured with rounded tops, and
may have flat bottoms. The border of a cumulus cloud
is clearly defined, and can have the appearance of cotton or cauliflower.
Cumulus clouds form at low altitudes (rarely above 2 km) but can grow very tall,
becoming cumulus congestus and possibly the even taller cumulonimbus clouds.
When cumulus clouds become taller, they have a greater chance of producing precipitation.
