Weather Alert in Pennsylvania
Special Weather Statement issued February 6 at 9:35PM EST by NWS State College PA
AREAS AFFECTED: Cambria; Somerset; Bedford
DESCRIPTION: A band of heavy snow showers and squalls has been observed along an approaching Arctic cold front in western Pennsylvania. This band is projected to move into Somerset, southern Cambria, and western Bedford Counties between 1030 PM and 1230 AM tonight. Snow squalls quickly reduce visibility and cause rapid accumulations of snow. The reduced traction and blinding visibility of a snow squall can make travel very dangerous very quickly. Consider avoiding or delaying travel while the band of heavy snow moves through the area. Rapid changes in visibility and potentially slick roads may lead to accidents. If you must travel, please use extreme caution and allow plenty of stopping distance. Avoid braking suddenly.

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.

Evaporation is the process which returns water from the earth
back to the atmosphere, and is another crucial process in the water cycle.
Evaporation is the transformation of liquid into gas, and it happens because
molecules are excited by the application of energy and turn into vapor.
In order for water to evaporate it has to be on the surface of a body of water.
