LOW PRESSURE WILL CONTINUE TO LIFT NORTHEAST AWAY FROM THE AREA
TODAY. HIGH PRESSURE WILL BUILD IN FROM THE WEST WEDNESDAY...THEN
PASS OFFSHORE THURSDAY. A COLD FRONT WILL MOVE THROUGH THE AREA

AS OF 635 AM TUESDAY...LOW PRESSURE OFF OF THE MID ATLANTIC COAST
EARLY THIS MORNING WILL CONTINUE TO LIFT NORTHEAST AWAY FROM THE
AREA TODAY WITH GRADUALLY IMPROVING CONDITIONS EXPECTED ACROSS
EASTERN NC LATER TODAY. THIS MORNING WE WILL HAVE TO DEAL WITH THE
SOUTHERN END OF THE WRAP AROUND MOISTURE ASSOCIATED WITH THE
LOW. LIGHT RAIN WAS CHANGING OVER TO LIGHT SNOW THIS MORNING AS
COLD AIR DEEPENS OVER THE AREA AND EXPECT A PERIOD OF VERY LIGHT
SNOW FOR THE NEXT COUPLE OF HOURS. THE GROUND IS WARM AND
SURFACE TEMPERATURES ARE FORECAST TO REMAIN JUST ABOVE FREEZING IN
MOST SPOTS THUS NOT EXPECTING ANY SIGNIFICANT ACCUMULATIONS OR
IMPACTS FROM THE WINTRY PRECIPITATION. IF A HEAVIER BURST OF SNOW
WERE TO DEVELOP IT COULD DEPOSIT A TRACE AMOUNT ON GRASSY
SURFACES MAINLY VICINITY OF THE ALBEMARLE SOUND AND NORTHERN OUTER
BANKS. THERE COULD ALSO BE AN ISOLATED ICY PATCH ON ELEVATED
SURFACES BUT WE ARE NOT EXPECTING MAJOR TRAVEL IMPACTS THIS MORNING.

EXPECTING ANY RESIDUAL LIGHT PRECIPITATION TO END BY AFTERNOON AS
DRIER AIR FILTERS INTO THE AREA. COULD SEE A FEW PEEKS OF THE SUN
ESPECIALLY WESTERN SECTIONS. COLD ADVECTION WILL CONTINUE AND WILL
HELP TO HOLD MAX TEMPERATURES DOWN WITH HIGHS IN THE LOWER TO
MIDDLE 40S.

SYSTEM TO IMPACT THE REGION LATE WEEK AS THE GFS AND ECMWF
CONVERGING ON A SOLUTION. BOTH THE GFS/ECMWF PRODUCING VERY LIGHT QPF
