Did it verify

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.

The nearest sounding before it

Nashville Metro, TN (KBNA), launched 12:00Z, 12.0 hours before the alert went out and 103 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
345 PM CDT MON JUN 16 2003

KOHX SHOWED SCATTERED SHOWERS AND THUNDERSTORMS THIS AFTERNOON
TO BE FOCUSED ALONG FRONTAL BOUNDARY PARKED OVER NORTHWESTERN
MIDDLE TENNESSEE. THIS IS THE FIRST DAY THAT THE PRECIPITATION
HAS BEEN ORGANIZED SO WELL ALONG THE FRONT, WITH DOPPLER ESTIMATED
RAINFALL AMOUNTS DEVIATING STRONGLY FROM LATEST MODEL QPF VALUES.

DUE TO THE INCREASED ACTIVITY ALONG FRONTAL ZONE, HIGH PWAS
NEAR 2 INCHES, AND LOCALIZED NEED FOR FLASH FLOOD WARNINGS, HAVE
INTRODUCED THE STATEMENT RAIN MAY BE HEAVY AT TIMES INTO THE FORECAST
FOR TONIGHTA AND TUESDAY.

AS PREVIOUS MODEL RUNS HAVE INDICATED, EXPECT SURFACE FRONTAL SYSTEM TO
CONTINUE A VERY SLUGGISH DRIFT TO THE EAST AND SOUTH NEXT SEVERAL
DAYS. WE MIGHT ACTUALLY SQUEEZE OUT ONE DRY DAY ON FRIDAY. HOWEVER,
HAD TO RE-INTRODUCE RAIN CHANCE INTO WEEKEND FORECAST, AS SURFACE
FLOW TURNS SOUTHEAST AGAIN AND VERY MOIST ENVIRONMENT RETURNS.

OVERALL, NOT MUCH CHANGE TO PREVIOUS FORECAST.
