...WINTER STORM WATCH IN EFFECT FROM LATE THURSDAY NIGHT THROUGH
FRIDAY EVENING...

THE NATIONAL WEATHER SERVICE IN MOUNT HOLLY HAS ISSUED A WINTER
STORM WATCH...WHICH IS IN EFFECT FROM LATE THURSDAY NIGHT THROUGH
FRIDAY EVENING. 

A LOW PRESSURE SYSTEM IS FORECAST TO MOVE THROUGH THE OHIO VALLEY 
FRIDAY AND THEN REDEVELOP OFF THE MIDDLE ATLANTIC COAST FRIDAY NIGHT 
BEFORE MOVING FARTHER OFFSHORE ON SATURDAY. AN ARCTIC HIGH PRESSURE 
SYSTEM TO ITS NORTH IS EXPECTED TO PROVIDE A FRESH SUPPLY OF COLD 
AIR FOR THIS SYSTEM.

THE RESULT IS A POTENTIAL FOR HEAVY SNOW ON FRIDAY INTO FRIDAY 
NIGHT. SNOW SHOULD ARRIVE BY DAYBREAK ON FRIDAY. WARMER AIR MOVING 
IN ALOFT MIGHT MIX OR CHANGE THE SNOW OVER TO SLEET AND POSSIBLY 
EVEN FREEZING RAIN. THIS IS MORE LIKELY TO OCCUR IN THE LEHIGH 
VALLEY AND ALONG THE INTERSTATE 80 CORRIDOR. THE HEAVIEST 
PRECIPITATION SHOULD TAPER OFF BY FRIDAY EVENING. THE FRIDAY 
AFTERNOON AND EVENING COMMUTE WILL BE DIFFICULT AT BEST.

INITIAL ESTIMATES FOR SNOW AND SLEET ACCUMULATIONS ARE 6 TO 12 
INCHES WITH THE HIGHEST AMOUNTS OVER THE HIGHER TERRAIN. 

PLEASE USE THE REST OF TODAY AND THURSDAY TO MAKE THE NECESSARY 
PREPARATIONS. THIS HAS THE POTENTIAL TO BE THE MOST WIDESPREAD AND 
DISRUPTIVE WINTER STORM OF THE SEASON SO FAR.

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.
