A WINTER STORM WATCH REMAINS IN EFFECT FROM LATE TONIGHT THROUGH
FRIDAY EVENING. 

THERE REMAINS AN INCREASED POTENTIAL FOR A SIGNIFICANT AMOUNT OF
SNOW FRIDAY INTO FRIDAY NIGHT. SNOW SHOULD ARRIVE TOWARD DAYBREAK
ON FRIDAY FROM WEST TO EAST. WARMER AIR MOVING IN ALOFT IS
EXPECTED TO ALLOW THE SNOW TO MIX WITH SLEET AND FREEZING RAIN
WITH SOME AREAS POSSIBLY SEEING A COMPLETE CHANGE OVER TO SLEET OR
FREEZING RAIN. THIS IS MORE LIKELY TO OCCUR IN THE LEHIGH VALLEY
AND ALONG THE INTERSTATE 80 CORRIDOR, WHICH WOULD HOLD DOWN THE
SNOW ACCUMULATIONS. THE HEAVIEST PRECIPITATION SHOULD TAPER OFF BY
EARLY FRIDAY EVENING. THE FRIDAY AFTERNOON AND EVENING COMMUTES
WILL BE GREATLY IMPACTED.

SNOW AND SLEET ACCUMULATIONS OF 6 TO 10 INCHES WITH LOCALLY
HIGHER AMOUNTS POSSIBLE OVER THE HIGHER TERRAIN ARE ANTICIPATED AT
THIS TIME. PORTIONS OF THE LEHIGH VALLEY SHOULD HAVE LESSER AMOUNTS
AS MIXING IS EXPECTED WITH EVEN A CHANGEOVER TO SOME FREEZING
RAIN.

THIS HAS THE POTENTIAL TO BE THE MOST WIDESPREAD AND DISRUPTIVE
WINTER STORM OF THE SEASON SO FAR. THEREFORE, USE TODAY TO MAKE
THE NECESSARY PREPARATIONS FOR THIS UPCOMING WINTER STORM.

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.

A WINTER STORM WATCH REMAINS IN EFFECT FROM LATE TONIGHT THROUGH
FRIDAY EVENING. 

THERE REMAINS AN INCREASED POTENTIAL FOR ANOTHER WINTRY MIX OF
SNOW, SLEET AND FREEZING RAIN. UNLIKE THE LAST SYSTEM, THIS ONE
WILL HAVE MORE MOISTURE ASSOCIATED WITH IT AND STORM TOTAL
PRECIPITATION AMOUNTS WILL BE HIGHER. SNOW SHOULD ARRIVE TOWARD
DAYBREAK FRIDAY FROM WEST TO EAST. WARMER AIR MOVING IN ALOFT IS
EXPECTED TO MIX OR CHANGE THE SNOW OVER TO SLEET AND FREEZING
RAIN, PROBABLY PLAIN RAIN IN THE SOUTHERN PARTS OF THE COUNTIES.
THE HEAVIEST PRECIPITATION SHOULD TAPER OFF BY EARLY FRIDAY
EVENING. TRAVEL ON FRIDAY WILL BECOME DIFFICULT AT TIMES.

ESTIMATED TOTAL SNOW AND SLEET ACCUMULATIONS AT THIS TIME ARE 3
TO AS MUCH AS 6 INCHES WITH THE HIGHEST AMOUNTS IN THE UPPER OR
NORTHERN PARTS OF THE COUNTIES. IN ADDITION, AROUND ONE QUARTER OF
AN INCH OF ICE COULD ALSO OCCUR. IF THE CHANGE OVER TO FREEZING
RAIN OCCURS SOONER, THE SNOW AND SLEET ACCUMULATIONS WILL BE HELD
DOWN.

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.
