...WINTER STORM WATCH IN EFFECT FOR SUNDAY AND SUNDAY NIGHT...

LOW PRESSURE WILL DEVELOP AND BEGIN TO STRENGTHEN OFF THE CAROLINA 
COASTLINE DURING THE DAY ON SUNDAY. AT THE SAME TIME, A COLD 
CANADIAN AIRMASS WILL BE IN PLACE OVER EASTERN PENNSYLVANIA AND 
NORTHWESTERN NEW JERSEY FROM AN AREA OF HIGH PRESSURE MOVING OFF THE 
NEW ENGLAND COASTLINE. DURING THE AFTERNOON HOURS ON SUNDAY, THE 
SYSTEM WILL MOVE NORTH-NORTHEAST ALONG THE MID-ATLANTIC COAST. 

SNOW IS EXPECTED TO REACH THE DELMARVA AND SOUTHERN NEW JERSEY EARLY 
SUNDAY MORNING AND WILL LIKELY OVERSPREAD THE ENTIRE REGION BY 
SUNDAY AFTERNOON. HOWEVER, EAST TO NORTHEAST WINDS AROUND THE LOW 
PRESSURE SYSTEM WILL BRING IN AIR OFF THE RELATIVELY WARM WATERS OF 
THE ATLANTIC OCEAN. THIS WILL CHANGE THE SNOW OVER TO RAIN IN 
SOUTHERN PORTIONS OF OUR AREA DURING THE DAY ON SUNDAY BEFORE 
ANY LARGE ACCUMULATIONS CAN OCCUR. HOWEVER, OVER PORTIONS OF EASTERN 
PENNSYLVANIA AND NORTHWESTERN NEW JERSEY...THE ATMOSPHERE WILL STAY 
COLD ENOUGH FOR SNOW OR A MIXTURE OF SNOW, SLEET, AND FREEZING RAIN. 

AT THIS TIME, THE EXACT TRACK AND TIMING OF THE LOW IS UNCERTAIN, 
MAKING THE EXACT LOCATION OF THE RAIN/SNOW LINE DIFFICULT TO 
DETERMINE AT THIS TIME. DESPITE THIS UNCERTAINTY, THERE IS A RISK 
FOR SIGNIFICANT ACCUMULATION OF SNOW AND ICE FOR THE POCONOS, LEHIGH 
VALLEY, AND NORTHWESTERN NEW JERSEY. TOTAL ACCUMULATIONS OF 6 INCHES 
OR MORE ARE POSSIBLE. BECAUSE OF THIS RISK, THE NATIONAL WEATHER 
SERVICE HAS ISSUED A WINTER STORM WATCH FOR THESE AREAS.

A WINTER STORM WATCH MEANS THERE IS A POTENTIAL FOR A SIGNIFICANT 
WINTER WEATHER EVENT WITHIN THE NEXT 36-48 HOURS, BUT NOT IMMINENT. 
FUTURE DRIVING AND WALKING CONDITIONS MAY BECOME HAZARDOUS, SO IT IS 
IMPORTANT TO MONITOR THE LATEST FORECASTS, AND LISTEN FOR LATER 
STATEMENTS AND POSSIBLE WARNINGS.

STAY TUNED TO NOAA WEATHER RADIO OR YOUR FAVORITE MEDIA OUTLET FOR 
FURTHER INFORMATION REGARDING THIS POTENTIAL WINTER STORM. ALSO, 
INFORMATION IS ALSO AVAILABLE ON OUR WEBSITE AT
