...THIS WEEK IS THE 2016 NOAA`S WINTER WEATHER AWARENESS WEEK FOR

THE STATE OF PENNSYLVANIA...

The National Weather Service will feature a different educational
topic each day. Today`s topic is Nor`easters and winter storms.

Last year powerful snowstorms developed along the east coast and
paralyzed cities across much of the northeast throughout the winter
months. This resulted in thousands of flights being cancelled
across the country, and these powerful storms disrupted hundreds
of thousands of lives ranging from electricity to transportation.
Not only was the east coastimpacted, but homes and farms across
the country saw the economic impacts due to mother nature.

Winter storms can morph into many shapes and sizes. A storm can
evolve into the size of a couple hundred miles in diameter and
weakens overnight, or blossom into a size that covers multiple
states and intensifies so quickly that the storms reaches
bombogenesis.

Large accumulations of snow can be produced by nor`easters,
overrunning, and sometimes lake effect storms in the state of
New York.  On average small snowfall events are often generated
by systems called Alberta clippers and scattered lake effect snow
showers.

Nor`easters are intense low pressure storm systems that generally
develop along the Gulf of Mexico, the track northeast along the
eastern seaboard. Its name comes from mariners that experienced
the strong northeast winds associated with the storm, but inland
they were known for their heavy snow and blizzard conditions. Some
memorable nor`easters in recent years include the presidents day
snowstorm of 2003, the February 11th and 12th storm of 2006, the
Valentines Day Snowstorm of 2007, and the snowstorm of February
25th and 26th,2010. Snowfall rates in a nor`easters can reach
2 to 4 inches per hour and can last for several hours.

The process called overrunning, can produce heavy snow in the state
of New York. This process occurs when warm air flows over cold air
that is hovering close to the the surface of the ground.
Overrunning happens mostly during the winter when the contrast
between two airmasses can be large. This process can also occur
when a large dome of high pressure is located over southeastern
Canada and a warm front is approaching our region from the south
or southwest.

Alberta clippers are very common to our region and quite often
bring a round of snow showers to the region. Alberta clippers are
low pressure systems that develop over the providence of Alberta,
Canada (located east of the rocky mountains). Alberta clippers move
east across central Canada, then they will typically drop southward
across the great lakes region, then eastward across the state of
New York. Alberta Clippers bring on average 1 to 3 inches of snow.

The following topics will be covered this week:
Thursday: Flooding and Ice Jams.
Friday: National Weather Service Winter Products.
