...WINTER STORM TAKING AIM ON THE CENTRAL U.S. TUESDAY NIGHT
THROUGH THURSDAY NIGHT...
A MAJOR WINTER STORM IS EXPECTED TO MOVE ACROSS THE CENTRAL U.S.
HEADING INTO THE CHRISTMAS HOLIDAY. THE TIMING AND STRENGTH OF THE
STORM IS SUCH THAT IT WILL HAVE A SIGNIFICANT IMPACT ON HOLIDAY
TRAVELERS. ANYONE PLANNING TRAVEL THROUGH THE CENTRAL U.S. SHOULD
CAREFULLY MONITOR FORECASTS OVER THE NEXT FEW DAYS.
THE INITIAL STAGES OF THE STORM ARE EXPECTED TO BEGIN IMPACTING
THE MIDWEST BY LATE TUESDAY. THE STORM WILL CONTINUE ITS INFLUENCE
OVER THE AREA WEDNESDAY AND THURSDAY...BEFORE EXITING THE CENTRAL
U.S. ON CHRISTMAS DAY. SOME LOCATIONS MAY EXPERIENCE A VARIETY OF
PRECIPITATION TYPES...WITH RAIN AND FREEZING RAIN CHANGING TO
SLEET AND SNOW AS THE SYSTEM MOVES ACROSS THE REGION.
IT IS IMPORTANT TO POINT OUT THAT IT IS STILL TOO EARLY TO TELL
EXACTLY WHEN OR WHERE THE MOST DANGEROUS WEATHER CONDITIONS WILL
OCCUR. WHILE THE FORECAST DATA HAS CONSISTENTLY POINTED TO STORM
DEVELOPMENT...THE EXACT TRACK AND TEMPERATURE PROFILE OF THE STORM
HAS BEEN VARYING A GREAT DEAL. THESE ARE KEY UNKNOWNS...SINCE A
SMALL CHANGE IN TEMPERATURE OR STORM MOVEMENT WILL HAVE A TREMENDOUS
IMPACT ON THE AMOUNT OF WINTER WEATHER A GIVEN LOCATION RECEIVES.
WE EXPECT NUMERICAL WEATHER DATA TO BEGIN TO CONVERGE ON A PREFERRED
SOLUTION OVER THE NEXT COUPLE OF DAYS...SO AGAIN...HOLIDAY TRAVELERS
ARE URGED TO CAREFULLY MONITOR THE LATEST FORECAST ON THIS STORM.
