...POSSIBLE SIGNIFICANT WINTER STORM TO IMPACT WESTERN AND
CENTRAL NORTH DAKOTA WEDNESDAY THROUGH CHRISTMAS DAY...
COMPUTER MODELS ARE LARGELY IN AGREEMENT THAT A STRONG LOW PRESSURE
SYSTEM WILL DEVELOP IN SOUTHEASTERN COLORADO ON TUESDAY EVENING AND
SLOWLY PUSH INTO THE UPPER MIDWEST BY CHRISTMAS MORNING. WHILE
UNCERTAINTY REMAINS WITH 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 THAT MOVES SLOWLY...THERE
IS THE POTENTIAL FOR HAZARDOUS WINTER WEATHER TO BE PROLONGED FOR A
COUPLE OF DAYS. THE HIGH VOLUME OF HOLIDAY TRAVEL WILL FURTHER
COMPLICATE THINGS.
AT PRESENT...IT APPEARS THAT MODERATE TO HEAVY SNOW ACCUMULATIONS
ARE POSSIBLE ACROSS A PORTIONS OF WESTERN AND CENTRAL NORTH
DAKOTA. WINDS ARE EXPECTED TO GRADUALLY INCREASE THROUGH THE
EVENT...SO NEAR BLIZZARD CONDITIONS ARE ALSO POSSIBLE. THE NATIONAL
