...SEVERE WEATHER OUTLOOK...

THE THREAT OF SEVERE WEATHER CONTINUES FOR LATE THIS AFTERNOON AND
TONIGHT.

RAIN COOLED AIR HAS LEFT A BOUNDARY SEPARATING COOL STABLE
AIR TO THE NORTH...AND WARMER MOIST AIR TO THE SOUTH.  THIS BOUNDARY
HAS PERSISTED ALL DAY...BUT HAS WEAKENED A BIT IN EASTERN SECTIONS OF
UPSTATE SOUTH CAROLINA...AND THE SOUTHERN PIEDMONT IN NORTH CAROLINA.
THE TEMPERATURE AND DEW POINT HAVE BEEN GRADUALLY RISING THROUGH THE
DAY AT MANY STATIONS.  THE COOL AIR REMAINED FIRMLY ENTRENCHED...FROM
AROUND GREENVILLE TO ANDERSON...AND ALONG THE EASTERN EDGE OF THE
MOUNTAINS...TO ABOUT SHELBY AND SPARTANBURG...BACK TO GREENVILLE.

STRONG TO SEVERE THUNDERSTORMS MOVING NORTHEAST FROM ALABAMA AND
GEORGIA WILL ENTER THE SOUTHWEST PART OF THE FORECAST AREA LATE THIS
AFTERNOON...AND SPREAD ACROSS THE SOUTHERN HALF OF THE AREA DURING
THE EVENING.  THERE IS A THREAT OF LARGE HAIL...EVEN AFTER THE STORMS
START MOVING OVER THE COLDER AIR AT AND NEAR THE SURFACE.  THE STORMS
WILL TEND TO WEAKEN RAPIDLY HOWEVER...AS LONG AS THE COLD AIR REMAINS
ENTRENCHED.

LATER THIS EVENING...THE BOUNDARY MAY ERODE MORE ALONG ITS SOUTHERN
EDGE...AND PLACES FROM HARTWELL AND ELBERTON...TO
GREENWOOD...LAURENS...UNION...CHESTER...AND MONROE...MAY GET INTO THE
WARMER AIR JUST TO THE SOUTH.  STORMS MOVING ALONG THIS BOUNDARY
COULD BE QUITE PRONE TO PRODUCE TORNADOES...AS WELL AS DAMAGING WINDS
AND LARGE HAIL.

A LARGE COMPLEX...OR LINE OF STORMS...IS EXPECTED TO DEVELOP TONIGHT
TO THE WEST...AND MOVE ACROSS MOST OF THE FORECAST AREA.  THIS
COMPLEX WILL BE CAPABLE OF LARGE HAIL...DAMAGING WINDS...AND POSSIBLY
SOME TORNADOES.  IT IS POSSIBLE SEVERE THUNDERSTORMS COULD DEVELOP
AGAIN MONDAY...AS A STRONG UPPER LEVEL SYSTEM MOVES ACROSS.

IN ADDITION...HEAVY RAINFALL IS LIKELY TONIGHT...WITH SOME FLASH
FLOODING OR URBAN FLOODING POSSIBLY DEVELOPING.

THIS COULD BECOME A DANGEROUS SEVERE WEATHER SITUATION
TONIGHT...ESPECIALLY FOR FOOTHILL AND PIEDMONT SECTIONS OF NORTHEAST
GEORGIA AND UPSTATE SOUTH CAROLINA.  COMMUNICATORS IN THOSE AREAS ARE
URGED TO BRIEF EMERGENCY MANAGEMENT OFFICIALS ON THIS LATEST
INFORMATION...AND ON ANY SEVERE WEATHER WATCHES WHICH MAY BE ISSUED.

STAY TUNED TO NOAA WEATHER RADIO OR THE MEDIA FOR THE LATEST WEATHER
INFORMATION OR SEVERE WEATHER WATCHES OR WARNINGS.
