...WINTER STORM WATCH REMAINS IN EFFECT FROM SUNDAY MORNING
THROUGH MONDAY MORNING...

A WINTER STORM WATCH REMAINS IN EFFECT FROM SUNDAY MORNING
THROUGH MONDAY MORNING. 

A STORM SYSTEM WILL MOVE TO THE ATLANTIC COAST TONIGHT AND THEN
INTENSIFY AS IT HEADS NORTHEAST ON SUNDAY, REACHING LONG ISLAND
SUNDAY EVENING. PRECIPITATION FROM THIS SYSTEM WILL BEGIN TO
OVERSPREAD THE REGION THIS EVENING...AND THEN CONTINUE THROUGH
SUNDAY. PRECIPITATION WILL THEN TAPER OFF TO SNOW SHOWERS 
SUNDAY NIGHT AS THE LOW PRESSURE SYSTEM MOVES SLOWLY AWAY FROM
THE REGION.

INITIALLY SOME LIGHT RAIN COULD DEVELOP THIS EVENING, THEN
STEADIER RAIN AND SNOW WILL FALL AFTER MIDNIGHT. AS TEMPERATURES
DROP TO NEAR FREEZING BY SUNDAY MORNING, THERE WILL BE MORE SNOW
AND LESS RAIN FALLING. BUT SINCE TEMPERATURES SHOULD REMAIN ABOVE
FREEZING MOST OF TONIGHT, ONLY AN INCH OR SO OF SNOW IS EXPECTED
TO BE ON THE GROUND BY SUNRISE ON SUNDAY.

DURING SUNDAY, HEAVIER PRECIPITATION WILL FALL. IT IS STILL UNCERTAIN
HOW LONG IT WILL TAKE FOR THE PRECIPITATION TO CHANGE TO ALL SNOW
AND THE FASTER THE CHANGEOVER, THE MORE SNOW THAT WILL ACCUMULATE.
BEFORE THE SNOW TAPERS OFF TO SNOW SHOWERS SUNDAY NIGHT, WE EXPECT
AN AVERAGE OF 4 TO 8 INCHES OF SNOW TO ACCUMULATE. SNOW ACCUMULATIONS
SHOULD BE HIGHLY VARIABLE WITH THE HIGHEST AMOUNTS OVER THE HIGHER
ELEVATIONS WHERE A FOOT OF SNOW CANNOT BE RULED OUT. OVER THE
SOUTHERN PARTS OF THE AREA, SNOW MAY ONLY ACCUMULATE A COUPLE
INCHES.

THE EXACT STORM TRACK REMAINS UNCERTAIN...AND A MINOR FLUCTUATION
TO THE EAST OR WEST WILL GREATLY IMPACT EXPECTED SNOW
ACCUMULATIONS. TRAVEL WILL BECOME EXTREMELY DIFFICULT LATE
TONIGHT AND SUNDAY DURING THE HEIGHT OF THE STORM. IN
ADDITION...POWER OUTAGES COULD OCCUR SUNDAY AS ANY HEAVY WET SNOW
COMBINES WITH GUSTY WINDS TO CAUSE TREE LIMBS AND POWER LINES TO
SNAP UNDER THEIR WEIGHT.

A WINTER STORM WATCH MEANS THERE IS A POTENTIAL FOR SIGNIFICANT
SNOW...SLEET...OR ICE ACCUMULATIONS THAT MAY IMPACT TRAVEL.
CONTINUE TO MONITOR THE LATEST FORECASTS.

...WINTER STORM WATCH NOW IN EFFECT FROM LATE TONIGHT THROUGH
MONDAY EVENING...

THE WINTER STORM WATCH IS NOW IN EFFECT FROM LATE TONIGHT THROUGH
MONDAY EVENING. 

ALTHOUGH SOME SNOW WILL FALL AT THE HIGHER ELEVATIONS THIS
MORNING, THE SNOW SHOULD CHANGE OVER TO RAIN BY LATE MORNING WITH
NO MORE THAN AN INCH OR TWO ACCUMULATION. 

A MORE SIGNIFICANT SNOW IS POSSIBLE LATE TONIGHT AND MONDAY AS THE
RAIN CHANGES BACK TO SNOW. 6 INCHES OF SNOW MAY ACCUMULATE ON
MONDAY, MAINLY OVER THE HIGHER ELEVATIONS. 

THE CAUSE FOR THE SNOW IS STORM SYSTEM THAT WILL MOVE NORTHEAST
ALONG THE NEW JERSEY COAST TODAY AND THEN DRIFT TO THE NORTHEAST
TONIGHT AND MONDAY. THE STORM WILL INITIALLY BRING WARMER
TEMPERATURES TO THE AREA TODAY, BUT COLDER AIR WILL RETURN ON THE
STORMS BACKSIDE LATE TONIGHT AND MONDAY. 

HOW FAST THE CHANGE FROM RAIN TO SNOW OCCURS AND ALSO HOW MUCH
MOISTURE IS REMAINS OVER THE REGION LATE TONIGHT AND MONDAY WILL
DETERMINE THE POTENTIAL SNOWFALL. HOWEVER, EVEN IF ALL AREAS DO
GET SNOW...THE SNOW ACCUMULATIONS SHOULD BE HIGHLY VARIABLE WITH
THE HIGHEST AMOUNTS OVER THE HIGHER ELEVATIONS.

A WINTER STORM WATCH MEANS THERE IS A POTENTIAL FOR SIGNIFICANT
SNOW...SLEET...OR ICE ACCUMULATIONS THAT MAY IMPACT TRAVEL.

...WINTER WEATHER ADVISORY IN EFFECT FROM MIDNIGHT TONIGHT TO
12 PM EDT MONDAY...
...WINTER STORM WATCH NO LONGER IN EFFECT...

THE NATIONAL WEATHER SERVICE IN MOUNT HOLLY HAS ISSUED A WINTER
WEATHER ADVISORY, WHICH IS IN EFFECT FROM MIDNIGHT TONIGHT TO
12 PM EDT MONDAY. THE WINTER STORM WATCH IS NO LONGER IN EFFECT.

AN AREA LOW PRESSURE WILL MOVE UP THE EAST COAST TONIGHT AND 
INTENSIFY AS IT DOES SO. AS MOISTURE CONTINUES TO MOVE ACROSS THE 
AREA, COLDER AIR WILL BE DRAWN INTO THE STORM LATER TONIGHT. THE 
ARRIVAL OF THE COLDER AIR WILL ALLOW THE RAIN TO MIX WITH AND THEN 
CHANGE TO WET SNOW LATE TONIGHT AND CONTINUE THROUGH THE DAY ON 
MONDAY. THE SNOW MAY FALL MODERATE AT TIMES LATE TONIGHT INTO EARLY 
MONDAY MORNING, THEN TEND TO DIMINISH IN INTENSITY DURING THE DAY ON 
MONDAY. 

TOTAL SNOW ACCUMULATIONS OF 1 TO 3 INCHES ARE EXPECTED IN THE 
VALLEYS WITH 3 TO 6 INCHES IN THE HIGHER ELEVATIONS. ROADS COULD 
BECOME RATHER SLIPPERY LATE TONIGHT AND EARLY MONDAY MORNING, 
HOWEVER THEN MAY TEND TO IMPROVE DURING THE DAYLIGHT HOURS ON MONDAY 
DUE TO THE STRONGER APRIL INDIRECT SUNLIGHT. 

AN ADDED COMPLICATION WILL BE THE INCREASING WINDS LATER TONIGHT AND 
MONDAY. WIND GUSTS TO AROUND 45 MPH COUPLED WITH THE WET SNOW ON 
TREE LIMBS WILL CAUSE MANY OF THEM TO BREAK. THIS WILL CAUSE 
SCATTERED POWER OUTAGES ESPECIALLY ON THE POCONO PLATEAU.

IF TRAVELING LATE TONIGHT AND ON MONDAY, BE PREPARED FOR SLIPPERY 
CONDITIONS ON UNTREATED ROADS.

A WINTER WEATHER ADVISORY MEANS THAT PERIODS OF SNOW, SLEET, OR
FREEZING RAIN WILL CAUSE TRAVEL DIFFICULTIES. BE PREPARED FOR
SLIPPERY ROADS AND LIMITED VISIBILITIES, AND USE CAUTION WHILE
DRIVING.
