.DISCUSSION...
AN UPPER LEVEL DISTURBANCE WILL PASS EAST ACROSS THE CAROLINAS 
THIS MORNING...RADIATING SCATTERED LIGHT SHOWERS ACROSS THE 
FORECAST AREA. RAINFALL AMOUNTS WILL REMAIN LIGHT...IN MANY 
CASES JUST ENOUGH TO WET THE SURFACE. THIS DISTURBANCE WILL 
EXIT THE AREA BY EARLY AFTERNOON...WITH RAINFALL TRANSITIONING 
TO SPOTTY SHOWERS TRIGGERED BY AFTERNOON HEATING...MAINLY FOR 
THE MOUNTAINS. CLOUDS WILL REMAIN WIDESPREAD THROUGH THE DAY...
BUT WILL SCATTER TONIGHT. 

UPPER LEVEL HIGH PRESSURE WILL THEN STRENGTHEN AND KEEP US IN 
A RATHER STAGNANT PATTERN...MAINTAINING A CHANCE FOR AFTERNOON 
AND EVENING SHOWERS AND THUNDERSTORMS THROUGH THE MIDDLE OF THE 
WEEK. WIDESPREAD WETTING RAIN IS NOT EXPECTED FOR THE NEXT SEVERAL 
DAYS. VENTILATION AND DISPERSION WILL CONTINUE TO BE HAMPERED BY 
RELATIVELY LIGHT TRANSPORT WINDS. MINIMUM RELATIVE HUMIDITY VALUES 
WILL REMAIN ABOVE 40 PERCENT THROUGH THE PERIOD.
