NATIONAL / LOCAL WEATHER FORECAST Wednesday Dec 26 – Friday Dec 28 2012

NATIONAL AND LOCAL WEATHER FORECAST CALLS FOR A STRONG WINTER STORM SHIFTING ITS IMPACT TO THE OHIO VALLEY AND INTERIOR NORTHEAST DURING THE NEXT COUPLE OF DAYS. SEVERE THUNDERSTORMS ARE FORECAST TO AFFECT THE SOUTHEASTERN U.S. ON WEDNESDAY.

WINTER STORMS CONTINUE ACROSS THE OHIO AND TENNESSEE VALLEYS, SPREADING INTO THE APPALACHIANS AND MID-ATLANTIC REGION. BLIZZARD WARNINGS ARE IN EFFECT FOR NORTHEASTERN ARKANSAS, SOUTHEASTERN MISSOURI, EXTREME WESTERN KENTUCKY, SOUTHERN ILLINOIS, A LARGE PORTION OF INDIANA, AND PORTIONS OF OHIO.

WINTER STORM WARNINGS AND WINTER WEATHER ADVISORIES ARE IN EFFECT FOR NORTHEAST TEXAS, AND FROM THE OHIO RIVER VALLEY INTO THE NORTHEAST. WINTER STORM WATCHES ARE IN EFFECT FOR PORTIONS OF NORTHERN NEW ENGLAND.

HIGH WIND WARNINGS ARE IN EFFECT FOR THE APPALACHIANS FROM EASTERN TENNESSEE AND WESTERN NORTH CAROLINA NORTHWARD INTO SOUTHWESTERN VIRGINIA. HIGH WIND WATCHES ARE IN EFFECT FOR COASTAL AREAS OF CONNECTICUT, RHODE ISLAND, AND MASSACHUSETTS.

ICE STORM WARNINGS AND FREEZING RAIN ADVISORIES ARE IN EFFECT FOR THE HIGHER ELEVATIONS OF WEST CENTRAL VIRGINIA AND EASTERN WEST VIRGINIA.

FLOOD WATCHES ARE IN EFFECT FOR PORTIONS OF EASTERN PENNSYLVANIA AND WESTERN NEW JERSEY.

A POWERFUL SYSTEM CURRENTLY MOVING THROUGH THE LOWER TENNESSEE VALLEY HAS ALREADY PRODUCED HEAVY SNOWFALL, SIGNIFICANT ICING, AND NUMEROUS TORNADOES. MUCH OF THE SAME WILL POSSIBLE AS IT ADVANCES FROM THE TENNESSEE VALLEY TO THE MID-ATLANTIC ON WEDNESDAY. MOIST AND UNSTABLE AIR WITHIN THE WEATHER SYSTEM WILL BRING WIDESPREAD SHOWERS AND THUNDERSTORMS ACROSS THE SOUTHEAST. A MODERATE RISK OF SEVERE WEATHER ALONG THE COASTAL CAROLINAS (INCLUDING THE OUTER BANKS) INCLUDES A TORNADO THREAT AND OTHER DAMAGING WINDS AS A LIKELY SQUALL LINE DEVELOPS.

WINTER STORMS ARE FORECAST TO CONTINUE BRINGING MODERATE TO HEAVY SNOWFALL. A SWATH OF OVER 6 INCHES OF SNOW WILL BE POSSIBLE FROM THE UPPER OHIO VALLEY, NORTHEASTWARD INTO THE INTERIOR NORTHEAST. 12 TO 18 INCHES OF SNOW FROM EXTREME WESTERN NEW YORK TO CENTRAL MAINE. A
MIXTURE OF FREEZING RAIN/SLEET WILL BE POSSIBLE ALONG THE RAIN/SNOW LINE. A QUARTER TO A HALF-INCH OF ICE ACCUMULATIONS MAY FALL OVER SECTIONS OF THE CENTRAL APPALACHIANS AS WELL AS NORTHEASTERN PENNSYLVANIA/SOUTHEASTERN NEW YORK. SNOW COULD DOMINATE WEST OF THE I-95 CORRIDOR AS FAR NORTH AS MASSACHUSETTS BEFORE WINTRY PRECIPITATION SPREADS ACROSS ALL OF NEW HAMPSHIRE AND MAINE.

ANOTHER ROUND OF PRECIPITATION WILL COVER MUCH OF THE WESTERN U.S. THROUGHOUT THE DAY, ALTHOUGH THE RAIN AND SNOW WILL GRADUALLY DECREASE AS MOISTURE DECREASES. THE BEST SNOWFALL ACCUMULATIONS SHOULD FALL ACROSS THE WASATCH AND CENTRAL ROCKIES WITH A FOOT OR MORE FORECAST.

SOME VERY COLD DAYS ARE FORECAST IN THE WAKE OF THE STRONG WINTER STORM PUSHING TOWARD THE MID-ATLANTIC. REGIONS NORTH OF THE RED RIVER ALONG TEXAS/OKLAHOMA BORDER WILL STRUGGLE TO RISE ABOVE THE FREEZING POINT ON WEDNESDAY, WHILE LOWS PLUMMET INTO THE TEENS OVERNIGHT. FARTHER SOUTH, FREEZING TEMPERATURES ARE POSSIBLE WEDNESDAY NIGHT ALL THE WAY TO NEAR THE WESTERN GULF COASTLINE.
