The radar

The Nashville radar (KOHX), 107 km from the middle of the area, began a volume at 09:31 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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 00:00Z, 9.5 hours before the alert went out and 111 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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Nashville, TN wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 14, 4:20 AM CDT, 8 minutes earlier.

Area forecast discussion, Jul 14, 4:20 AM CDT, 8 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
420 AM CDT WED JUL 14 2004

.DISCUSSION...
MIDDLE TENNESSEE GETTING READY FOR SOME MORE ROCKING AND ROLLING.

MIDDLE TENNESSEE IS JUST RECOVERING FROM A DAMAGING MCS THAT RACED
ACROSS OUR AREA OVERNIGHT, BLOWING TREES DOWN RIGHT AND LEFT AND
KNOCKING POWER OUT TO THOUSANDS OF CUSTOMERS. NOW, UPSTREAM, WE HAVE
A SIMILAR CREATURE ROARING DOWN ON US FROM THE NORTHWEST AND THREATENING
SEVERE WEATHER FOR MUCH OF OUR CWA (ESPECIALLY THE NORTHEASTERN
HALF).

UNTIL SURFACE BOUNDARY CROSSES MIDDLE TENNESSEE LATE TODAY AND
TONGIHT, BELEIVE CHANCE FOR THUNDERSTORMS WILL BE HIGH AND HAVE GONE
WITH 50-60% POPS FOR THE EASTERN TWO-THIRDS OF OUR FORECAST AREA.
IN LINE WITH SPCS DAY1 OUTLOOK, AND IMPENDING SEVERE STORMS TO OUR
NORTHWEST, HAVE MENTIONED THE POSSIBILITY OF A FEW SEVERE STORMS IN
THE ZFP TEXT.

WHILE DAMAGING WINDS WERE THE MAIN PROBLEM FROM LAST NIGHTS STORMS,
SDF AND OHX INDICATED A TREND TOWARD SOME HAILERS BY THE LATE NIGHT
HOURS. THUS, WOULDNT BE SURPRISED TO SEE HAIL TO AT LEAST NICKEL TO
QUARTER SIZE HAIL WITH SOME OF THE BIGGER STORMS TODAY.

STORMS FINALLY EXIT THE REGION TONIGHT, HERALDING A TURN TO SOME
DRY AND LESS HUMID CONDITIONS THROUGH LATE WEEK.

.BNA WATCHES/WARNINGS/ADVISORIES...NONE.
