A brutal cold snap for this part of the country occurred in January, otherwise the severity of the cold was not the main highlight of the winter. The persistence of the cold air was news-worthy.

What caused the prolonged period of cold weather and frequent snow events? A feature in the upper levels of the atmosphere, known as the "polar vortex," persistently dug in its heels over southeast Canada. This "polar vortex" was mainly responsible for maintaining a cold northwest wind flow over much of the eastern and central U.S. A second branch of the jet stream originating over the tropical Pacific Ocean brought moist storm systems eastward across the southern U.S. As a result, much of the winter was snowier over the mid-Atlantic region and lower Ohio Valley than it was over the Great Lakes region.

March put an end to an unusually long winter for our region. Although significant snow can occur in March, as it did on March 14, 1999, such was not the case this 2002-03 season.
