Weather Alert in Alaska
Winter Weather Advisory issued February 26 at 4:06PM AKST until February 27 at 12:00AM AKST by NWS Juneau AK
AREAS AFFECTED: Prince of Wales Island
DESCRIPTION: ...POTENTIAL OVERRUNNING SNOW EVENT FOR SUNDAY INTO MONDAY... .Cold Arctic air is expected to move into the panhandle for the end of the week into next week. With the cold air in place, moisture associated with a low over the Gulf into the Bering Sea is expected to move over the area. With the warmer nature of the moisture and colder air at the surface, snow is expected to fall across the Panhandle. Current guidance suggests that the most significant snow will be over the parts of the Central Panhandle that holds onto the cold air longer. There is the potential that this overrunning snow event lasts into the middle to end of next week. This will depend on how long the cold air persists through the Inner Channels. Meanwhile snow showers continue into the Thursday night for parts of the panhandle. * WHAT...Snow. Additional snow accumulations of 1 to 3 inches. * WHERE...Prince of Wales Island. * WHEN...Until midnight AKST tonight. * IMPACTS...Travel could be difficult.

Condensation is the process which creates clouds, and therefore
it is a crucial process in the water cycle.
Condensation is the change of matter from a state of gas into a state of liquid,
and it happens because water molecules release heat into the atmosphere and
become organized into a more closely packed structure, what we might see as
water droplets.
Water is always present in the air around us as a vapor, but it's too small for
us to see. When water undergoes the process of condensation it becomes organized
into visible water droplets. You've probably seen condensation happen before on the
surface of a cold drink!

Next Topic: Cumulus Clouds
The final form taken by a growing cumulus cloud is the
cumulonimbus cloud, which is very tall and dense.
The tower of a cumulonimbus cloud can soar 23 km into the atmosphere, although
most commonly they stop growing at an altitude of 6 km.
Even small cumulonimbus clouds appear very large in comparison to other cloud types.
They can signal the approach of stormy weather, such as thunderstorms or blizzards.
