...HIGH IMPACT WINTER STORM WILL MOVE OUT OF THE MIDWEST AND INTO
THE NORTHEAST AND NORTHERN MID-ATLANTIC REGION...

...RAIN AND SNOW EXPECTED IN THE NORTHWESTERN CORNER OF THE
NATION...

A HIGH IMPACT WINTER STORM WILL MOVE OUT OF THE MIDWEST AND INTO
THE NORTHEAST AND NORTHERN MID-ATLANTIC REGION.  THE MAIN SURFACE
CYCLONE DRIVING THE EVENT IS EXPECTED TO TAKE A STEADY TRACK
THROUGH THE OHIO VALLEY SUNDAY NIGHT...BEFORE RE-DEVELOPING AND
RAPIDLY DEEPENING OFF THE SOUTHERN NEW ENGLAND COAST ON MONDAY.  A
WIDE AXIS OF MODERATE TO HEAVY SNOW WILL CONTINUE TO DEVELOP TO
THE NORTH OF A FRONTAL BOUNDARY STRETCHED EASTWARD FROM THE
LOW...WHICH WILL RESULT IN AN EXPANSIVE AREA OF HEFTY SNOWFALL
ACCUMULATIONS STRETCHING ACROSS THE LOWER GREAT LAKES...THROUGH
NEW YORK...AND INTO THE NORTHEAST.  IN ADDITION TO THE
SNOW...WINDS WILL BE STRONG AND GUSTY SURROUNDING THE DEEPENING
SURFACE LOW.  COLD AIR INITIALLY ENTRENCHED IN ACROSS CENTRAL
PENNSYLVANIA AND SOUTHERN NEW ENGLAND SHOULD SET UP A ZONE OF
SLEET AND FREEZING RAIN TO THE SOUTH OF THE HEAVY SNOW AXIS.
FARTHER SOUTH...A COLD FRONT EXTENDING SOUTHWARD FROM THE LOW WILL
TRIGGER SHOWERS...AND EVEN A FEW THUNDERSTORMS...AS IT PRESSES
EAST TOWARDS THE CENTRAL TO SOUTHERN APPALACHIANS AND OFF THE
ATLANTIC COAST.

A SERIES OF COLD FRONTS APPROACHING THE WEST COAST WILL BRING
WIDESPREAD PRECIPITATION INTO THE NORTHWESTERN CORNER OF THE
NATION.  ABOVE NORMAL TEMPERATURES ACROSS THE REGION SHOULD KEEP
SNOW LEVELS FAIRLY HIGH...BUT SOME LIGHT TO MODERATE SNOWFALL
ACCUMULATIONS WILL STILL BE POSSIBLE AS PRECIPITATION SPREADS
EASTWARD OVER THE HIGHER ELEVATION OF THE NORTHERN ROCKIES.
TOWARDS THE END OF FORECAST PERIOD...MOISTURE RETURNING FROM THE
WESTERN GULF OF MEXICO SHOULD FUEL RAIN OVER SOUTH TEXAS BY EARLY
TUESDAY.
