A PAIR OF WEATHER SYSTEMS TREKKING ACROSS THE OHIO RIVER VALLEY
AND GULF COAST RESPECTIVELY WILL EVENTUALLY MERGE ALONG THE
EASTERN SEABOARD SOMETIME LATE SATURDAY. CONSEQUENTLY...A SURFACE
WAVE OF LOW PRESSURE IS FORECAST TO DEVELOP NEARBY THE
SOUTHEASTERN U.S. COAST WITH AN EVENTUAL TRACK TO THE NORTH. WHILE
THERE IS STILL PLENTY OF UNCERTAINTY REGARDING THE ACTUAL TRACK OF
THIS SURFACE CYCLONE...IT WILL REMAIN CLOSE ENOUGH TO THE EAST
COAST TO ENHANCE THE RISK FOR SNOWFALL FROM THE I-95 CORRIDOR
EASTWARD. RAPID DEEPENING OF THIS SURFACE LOW IS
EXPECTED...ESPECIALLY AS IT MOVES FROM THE COASTAL CAROLINAS UP
TOWARD THE SOUTHERN NEW ENGLAND COAST BY MONDAY MORNING. IN TERMS
OF SNOWFALL AMOUNTS...AN AREA SPANNING FROM NORTHERN GEORGIA UP
INTO SUOTHERN VIRGINIA CAN EXPECT 2 TO 4 INCHES WITH HIGHER
AMOUNTS IN THE 6 TO 10 INCH RANGE OVER THE SMOKY MOUNTAINS THROUGH
SUNDAY MORNING. IN ADDITION...ENOUGH COLD AIR WILL BE IN PLACE TO
HELP PRODUCE A FEW INCHES OF SNOW JUST TO THE WEST OF THE OUTER
BANKS. 

THE NEXT STORM SUMMARY WILL BE ISSUED BY THE HYDROMETEOROLOGICAL
PREDICTION CENTER AT 1000 AM EST. PLEASE REFER TO YOUR LOCAL
NATIONAL WEATHER SERVICE OFFICE FOR ADDITIONAL INFORMATION ON THIS
EVENT.
