...PRE THANKSGIVING TO THANKSGIVING DAY STORM TO PUSH FROM THE MID
MISSISSIPPI/OHIO VALLEY TODAY INTO THE NORTHEAST ON THURSDAY
SPREADING RAINFALL AND NEW ENGLAND SNOWFALL IN ITS VICINITY...
...INCREASINGLY BELOW AVERAGE TEMPERATURES SPILL OUT INTO THE
GREAT PLAINS AND MISSISSIPPI VALLEY THROUGH THE END OF THE WEEK...
...LAKE EFFECT SNOWS CONTINUE AND WILL EXPAND AND INTENSIFY WITH
TIME...
A DYNAMIC MID-LATITUDE CYCLONE TRACKS THROUGH THE MISSISSIPPI
VALLEY, TENNESSEE VALLEY, UPPER OHIO VALLEY, AND NEAR THE NEW
ENGLAND COAST THROUGH THANKSGIVING DAY. SCATTERED SHOWERS AND
THUNDERSTORMS SPREAD INTO THE EAST COAST TONIGHT AND PROGRESSIVELY
SHIFT EASTWARD. A SWATH OF MODERATE TO HEAVY SNOWFALL IS LIKELY TO
DEVELOP ACROSS PORTIONS OF THE INTERIOR NORTHEAST -- WINTER STORM
WATCHES ARE IN EFFECT FOR PORTIONS OF CENTRAL NEW ENGLAND RELATED
TO THE HEAVY SNOW THREAT.
ELSEWHERE, LAKE EFFECT SNOW SHOWERS ACROSS THE UPPER GREAT LAKES
MAY YIELD ANYWHERE FROM 4-8 INCHES OVER THE NORTHERN COASTLINE OF
THE UPPER PENINSULA OF MICHIGAN AS WELL AS NORTHERN PARTS OF THE
LOWER PENINSULA. A DISTURBANCE ALOFT WILL ALLOW FOR THE
DEVELOPMENT OF A NEW COLD FRONT LATE ON THANKSGIVING WHICH MOVES
EAST AND SOUTH AHEAD OF A STRONG AND COLD SURFACE HIGH. IN THE
WAKE OF THIS FRONT, AS TEMPERATURES COOL FURTHER, LAKE EFFECT
SNOWS SHOULD EXPAND AND INTENSIFY AS THEY INTERACT WITH RECORD
WARM GREAT LAKES TEMPERATURES FOR SO LATE NOVEMBER. FLORIDA WILL
REMAIN MILD TO WARM.
