NATIONAL WEATHER SERVICE NASHVILLE TN
829 PM CDT MON MAY 5 2003

...TORNADO WATCH UNTIL 10 PM CDT...

SEVERE THUNDERSTORMS CONTINUE TO DEVELOP WEST OF MIDDLE TENNESSEE AND
MOVE EAST ACROSS THE FORECAST AREA. ONE AFTER THE OTHER....THE

SMITHVILLE...TO NASHVILLE...TO ASHLAND CITY...TO BIG SANDY. AT
THIS TIME...THE GREATEST THREAT FROM THE STORMS IS FLASH FLOOD
PRODUCING RAIN HOWEVER...THE ATMOSPHERIC WIND PROFILE STILL SUGGESTS
THE POSSIBILITY OF TORNADO DEVELOPMENT.

IT MAY BE WISHFUL THINKING BUT...EXPECT THE CURRENT THUNDERSTORM
ACTIVITY TO WEAKEN AND DIMINISH IN COVERAGE AND INTENSITY LATER THIS
EVENING. THE AREA OF GREATEST RISK FOR SEVERE STORMS APPEARS TO
SHIFT FROM TENNESSEE TO ACROSS THE DEEP SOUTH OVERNIGHT.

.BNA...TORNADO WATCH UNTIL 10 PM CDT. DESTRUCTIVE TORNADOES...LARGE
