Area forecast discussion, Jun 24, 9:55 PM EDT, 2 hours 24 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
955 PM EDT SUN JUN 24 2001

FORECAST TRENDS GOOD SO FAR. SCATTERED SHOWERS AND THUNDERSTORMS
ARE PROPAGATING INTO MORE STABLE AIR AND BELIEVE THEY WILL GRADUALLY
DIMINISH AS WE GET CLOSER TO MIDNIGHT. PLENTY OF OUTFLOWS HAVE COME
OUT OF STORMS THIS EVENING SO NEW DEVELOPMENT COULD POP UP MOST
ANYWHERE OUTSIDE THE MOUNTAINS FOR A BRIEF PERIOD. MAIN ACTIVITY
HOWEVER SHOULD REMAIN ALONG BEST CONVERGENCE AXIS FROM JUST EAST OF
SPARTANBURG TO WEST OF STATESVILLE.

I DO NOT PLAN TO UPDATE AT THIS TIME BUT MAY TOWARDS MIDNIGHT OF
THE SHOWERS AND THUNDERSTORMS DIMINISH AS EXPECTED.

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