Here it comes!


. WINTER STORM WATCH IN EFFECT FROM TUESDAY EVENING THROUGH WEDNESDAY MORNING...

THE NATIONAL WEATHER SERVICE IN STERLING VIRGINIA HAS ISSUED A WINTER STORM WATCH... WHICH IS IN EFFECT FROM TUESDAY EVENING THROUGH WEDNESDAY MORNING.

PRECIPITATION IS EXPECTED TO BEGIN TUESDAY AFTERNOON IN THE CENTRAL SHENANDOAH HIGHLANDS AS A PERIOD OF SNOW... MOVING NORTH TO THE PENNSYLVANIA BORDER EARLY TUESDAY EVENING. PRECIPITATION IS EXPECTED MIX WITH SLEET... BECOME HEAVIER TUESDAY EVENING AND CHANGE TO RAIN. HOWEVER TEMPERATURES AT THE SURFACE WILL STAY BELOW FREEZING... SO RAIN THAT FALLS WILL FREEZE ON IMPACT. FREEZING RAIN IS EXPECTED TO CONTINUE THROUGHOUT TUESDAY NIGHT BEFORE WARMER AIR MOVES IN WEDNESDAY MORNING.

ONE QUARTER INCH OF FREEZING RAIN ACCUMULATION IS POSSIBLE. THE MOST LIKELY PLACE TO RECEIVE THAT MUCH WOULD BE IN THE COLDER LOW LYING AREAS OF THE SHENANDOAH VALLEY AND ALLEGHENY HIGHLANDS.

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.
