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

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

AFTER A DAY OF RECORD BREAKING HIGH TEMPERATURES AS HARD AS IT
MIGHT BE TO FATHOM, A WINTRY WEATHER PRECIPITATION EVENT IS
LIKELY STARTING TUESDAY.

A COLD FRONT WILL MOVE THROUGH THE REGION TONIGHT WITH ARCTIC AIR 
BEHIND IT AND WAVES OF LOW PRESSURE ARE FORECAST TO MOVE ALONG THE 
FRONTAL BOUNDARY. A COUPLE OF PRECIPITATION SURGES ARE FORECAST TO 
AFFECT THE REGION. 

PRECIPITATION SHOULD BE RAIN STARTING TUESDAY MORNING. BY
TUESDAY AFTERNOON IT WILL BE COLD ENOUGH ALOFT FOR PRECIPITATION
TO CHANGE TO SLEET AND OR SNOW. AS MORE COLDER AIR MOVES IN, ITS
POSSIBLE THAT PRECIPITATION MIGHT CHANGE TO ALL SNOW TUESDAY
EVENING. THE PROCESS IS THEN EXPECTED TO REVERSE ITSELF LATER
TUESDAY NIGHT AND WEDNESDAY MORNING AS WARMER AIR MOVES IN ALOFT.
THIS WILL INCREASE THE LIKELIHOOD OF FREEZING RAIN OCCURRING. THE
PRECIPITATION SHOULD CHANGE TO PLAIN RAIN RAIN AS WEDNESDAY
CONTINUES.

PRIOR TO THE CHANGE, THERE COULD BE A COUPLE OF INCHES OF SNOW AND 
SLEET AS WELL AS A GLAZE OF ICE TO AROUND ONE QUARTER OF AN INCH.
THIS EVENT WOULD START IMPACTING THE EVENING COMMUTE ON TUESDAY AND 
ALSO HAVE AN EFFECT ON THE WEDNESDAY MORNING COMMUTE.

PLEASE USE THE TIME PRIOR TO THE EVENT TO MAKE THE NECESSARY 
PREPARATIONS. 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.
