"Residents and visitors in the South this weekend into next week should be prepared for a spell of unseasonably cold weather with wind.
The chill will hit at a time when many college students, families and individuals flock to the South for a brief break from the winter.
Winds high in the atmosphere, known as the jet stream, will take a big southward dip over eastern North America, reaching as far as the northwestern Caribbean this weekend.
The end result will be temperatures averaging 10 to 20 degrees below normal across the South, the eastern Gulf of Mexico and the Bahamas."
