What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before this severe thunderstorm warning went out at Mar 16, 9:50 AM EST, 1 hour 24 minutes earlier.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
950 AM EST SAT MAR 16 2002

KGSP RADAR SHOWS SOLID LINE OF SHOWERS/THUNDERSTORMS OVER THE NC
MOUNTAINS...POISED TO MOVE OUT OVER THE NC FOOTHILLS. LIGHTNING
ACTIVITY HAS DROPPED SIGNIFICANTLY OVER THE PAST HOUR....BUT BAND OF
PRECIP REMAINS ESSENTIALLY INTACT FOR THE TIME BEING. KFFC RADAR
SHOWS SIGNIFICANTLY LESS ACTIVITY OVER NE GA...BUT ANOTHER LARGER
AREA OF CONVECTION MOVING IN FROM AL. IT WOULD APPEAR THAT THE BEST
CHANCE FOR RAIN WILL BE ACROSS THE NORTHERN ZONES FOR THE NEXT
SEVERAL HOURS. WILL BE FORCED TO REGROUP AND GO CATEGORICAL ACROSS
THE NC FOOTHILLS...AND PERHAPS ACROSS NW PIEDMONT AS WELL. WILL MAKE
THAT CALL JUST BEFORE UPDATING AROUND 1030 TO 11AM ONCE PRECIP IS
MOVING OUT OF MOUNTAINS. THAT WILL ALLOW ME TO PERHAPS DROP BACK TO
CHANCE POP ACROSS MOUNTAINS FOR AFTERNOON. THE SC FOOTHILLS/PIEDMONT
AND NE GA ARE ANOTHER STORY. WITH 850 MB FLOW COMING AROUND TO
WESTERLY...IN THESE SITUATIONS...WE TYPICALLY SEE MUCH LESS PRECIP
ACROSS UPSTATE SC. KFFC RADAR WOULD SEEM TO SUPPORT THAT IDEA. WILL
CONSIDER DROPPING POP BACK TO A LOWER CHANCE ACROSS PART OF THE
UPSTATE.

TEMPS ARE A PROBLEM TOO...AS SEVERAL GROUPS ARE AT OR ABOVE WARM
FORECAST HIGHS AT THIS EARLY HOUR. WILL HAVE TO BUMP UP AT LEAST ONE
CAT AHEAD OF PRECIP BAND.

.GSP...
GA...NONE.
NC...NONE.
SC...NONE.
