.DISCUSSION...

A COLD FRONT WILL MOVE EAST OF THE REGION THIS MORNING ALLOWING DRIER AIR 
TO SLOWLY FILTER IN ACROSS THE AREA TODAY INTO THIS EVENING. NORTHWEST 
FLOW BEHIND THE FRONT WILL RESULT IN COLDER TEMPERATURES LATER TONIGHT INTO 
WEDNESDAY. A STORM SYSTEM MOVING UP ALONG THE CAROLINA COAST WILL 
BRING THE NEXT ROUND OF PRECIPITATION LATER TONIGHT THROUGH MUCH OF WEDNESDAY.
ANOTHER UPPER LEVEL DISTURBANCE FOLLOWING THIS SYSTEM COULD RESULT IN ANOTHER PERIOD 
OF LIGHT SNOW WEDNESDAY NIGHT INTO EARLY THURSDAY BEFORE MUCH DRIER AND WARMER AIR 
ARRIVES OVER THE WEEKEND INTO EARLY NEXT WEEK.
