RESPECT TO SPECIFIC IMPACTS OF THIS STORM SYSTEM...THERE ARE TWO
CHARACTERISTICS THAT ARE OF CONCERN. FIRST...THE VAST SIZE OF THE
STORM. THERE IS THE POSSIBILITY THAT WINTER WEATHER COULD EXTEND
FROM THE GREAT LAKES ALL THE WAY WEST INTO THE NORTHERN HIGH
PLAINS. SECOND...THE SLOW MOVEMENT OF THE STORM. WITH A STRONG LOW

WEATHER TO BE PROLONGED FOR A COUPLE OF DAYS. THE HIGH VOLUME OF
HOLIDAY TRAVEL WILL FURTHER COMPLICATE THINGS.

ARE POSSIBLE ACROSS A PORTION OF WESTERN AND CENTRAL NORTH
DAKOTA. WINDS ARE EXPECTED TO GRADUALLY INCREASE THROUGH THE
