AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
850 PM CDT SAT OCT 13 2001

EVENING WEATHER SHIFTED FROM POSSIBILITY OF SEVERE STORMS TO A
FLOODING SITUATION. ABUNDANT MOISTURE AND PLENTY OF WIND
ENERGY...BUT INSTABILITY LACKING. EVENING SOUNDING SHOWED POWERFUL
VEERING WIND FIELD...WITH A MERE 24 J/KG CAPE. ZONES WERE ALREADY
UPDATED TO REMOVE SEVERE AND REDUCE WORDING TO SHOWERS WITH JUST A
FEW THUNDERSTORMS.

SURFACE MAP HAS A TROUGH ALONG TN RIVER...MARKING BACK EDGE OF
HEAVIEST RAIN. MAIN FRONT FROM NEAR ST LOUIS...SOUTHWEST ACROSS AR.
UPPER LOW SPINNING FROM EAST TX...SETTING OFF SOME NEW SHOWER AND
THUNDERSTORM DEVELOPMENT IN SOUTHWEST AR AND LA.

MODELS INDICATED VERY STRONG LOW LEVEL MOISTURE CONVERGENCE OVER
WESTERN MID TN THIS EVENING...AND THIS AXIS WILL WEAKEN JUST
SLIGHTLY AS IT SLOWLY MOVES TO THE PLATEAU OVERNIGHT. FLOODING
CONDITIONS WILL GRADUALLY SUBSIDE OVERNIGHT...ALTHOUGH RUNOFF WILL
PROLONG SOME OF THE ON-GOING FLOODING LATE THIS EVENING.

SO FAR...MOST OF THE PROBLEMS HAVE BEEN IN AREAS THAT RECEIVED THE
MOST SIGNIFICANT RAINFALL DURING THE PAST FEW DAYS...IN THE
WESTERN-MOST COUNTIES OF MID TN. SO...AS THE BATCH OF HEAVIEST
RAINFALL MOVES EASTWARD...FEWER FLOODING PROBLEMS ARE EXPECTED.
FARTHER EAST...MAIN CONCERN WILL BE URBAN STREET FLOODING.

NO ADDITIONAL UPDATES PLANNED THIS EVENING. IF ANY ARE ISSUED...WILL
BE ONLY MINOR ADJUSTMENTS.

.BNA...FLASH FLOOD WATCH ALL OF MIDDLE TENNESSEE EXCEPT CUMBERLAND
       PLATEAU UNTIL 4 AM.
