Snow Blankets the Eastern United States!
News story originally written on March 5, 2003

Last winter there was very little snow in the Northeast United States but this winter there is tons of the white fluffy stuff! Several huge snowstorms have dumped feet of snow in places like Washington, D.C., Baltimore, Philadelphia, New York City, and Boston.

So what caused all this snow? The answer is in the air! Air may not look like much, but changes in air pressure over the Atlantic Ocean can cause snowy weather a few thousand miles away in New York!

A low-pressure system over the North Atlantic brings cold air down from the Arctic. It mixes with a high-pressure system that pulls moist air up from the warm tropics. The warm moist air hits the cold air from the Arctic producing snowstorms, some of which roll towards the East coast. During some winters, these pressure systems can become very strong producing plenty of snow. This is one of those winters!
