Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
919 PM CDT TUE MAY 6 2003

CURRENTLY, THUNDERSTORMS ARE OCCURRING TO OUR SOUTHWEST AND
NORTHWEST, BUT ALL IS QUIET IN MIDDLE TENNESSEE THIS HOUR. EVENING
SOUNDING FROM OLD HICKORY GIVES A LIFTED INDEX OF -4.6, WITH A
CONVECTIVE AVAILABLE POTENTIAL ENERGY OF 1386 J/KG. ATMOSPHERE IS A
TAD DRY, WITH PRECIPITABLE WATER JUST 1.20 INCHES AND WITH
SIGNIFICANT DRYING IN THE MID AND UPPER LEVELS, BUT THAT CAN ALWAYS
CHANGE.

VARIOUS SURFACE ANALYSES AT 01Z SHOW A BULLSEYE OF -10 LIFTED
INDICES CENTERED OVER EXTREME SOUTHEAST MISSOURI, WITH GREATEST
SURFACE PRESSURE FALLS EXTENDING FROM NASHVILLE WESTWARD. MEANWHILE,
LATEST CONVECTIVE OUTLOOK FROM SPC SHOWS ALL OF MIDDLE TENNESSEE
UNDER A SLIGHT RISK FOR OVERNIGHT SEVERE WEATHER, WITH MODERATE RISK
CREEPING INTO OUR EXTREME NORTHWEST COUNTIES.

HAVE UPDATED THE ZONE FORECAST PRODUCT FOR INCLUDE MENTION OF THE
FLOOD WATCH THAT WAS ISSUED EARLIER, BUT HAVE MADE NO CHANGES TO THE
ACTUAL FORECAST. MOST RECENT MODEL RUNS SHOW PEAK TIME FOR OVERNIGHT
CONVECTION AROUND 09Z, SO BELIEVE IT WILL BE SEVERAL HOURS BEFORE
THUNDERSTORMS EITHER MOVE INTO OR DEVELOP OVER THE MID STATE.

.BNA...FLOOD WATCH ALL OF MIDDLE TENNESSEE AND THE CUMBERLAND
PLATEAU TONIGHT AND TOMORROW MORNING.
