Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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, 7.7 hours before the alert went out and 92 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 flash flood 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 flash flood warning went out at Jul 6, 9:06 AM CDT, 5 hours 37 minutes earlier.

Area forecast discussion, Jul 6, 9:06 AM CDT, 5 hours 37 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
906 AM CDT WED JUL 6 2005

.DISCUSSION...
MAJOR FEATURE THIS MORNING IS T.S. CINDY. AT 4 AM...THE CENTER OF
THE STORM WAS LOCATED ABOUT 25 MILES EAST-NORTHEAST OF NEW ORLEANS.
AT 830 AM...THE CENTER APPEARED TO BE IN SOUTHERN MISSISSIPPI BETWEEN
HATTIESBURG AND GULFPORT. MOVEMENT WAS NORTHEAST AT 14 MPH. A
LARGE RAIN SHIELD EXTENDED NORTH AND EAST OUT FROM THE CENTER OF THE
STORM AFFECTING MOSTLY SOUTHERN ALABAMA AND THE FLORIDA PANHANDLE.
T.S. CINDY IS EXPECTED TO CONTINUE ON A NORTHEAST TRACK AT ABOUT
THE SAME SPEED. THAT WOULD PLACE THE CENTER IN CENTRAL ALABAMA NEAR
ANNISTON ALABAMA BY MIDNIGHT TONIGHT. THIS MOVEMENT WOULD KEEP THE
BULK OF THE RAIN WELL SOUTH AND EAST OF MIDDLE TENNESSEE. THE
SOUTHERN CUMBERLAND PLATEAU AREA HAS THE BEST CHANCE FOR A
SIGNIFICANT RAIN WITH AMOUNTS NEAR ONE INCH POSSIBLE.

A WEAK SURFACE BOUNDARY EXTENDS ACROSS SOUTHERN MIDDLE TENNESSEE THIS
MORNING. NOT A LOT OF DISCONTINUITY ACROSS THE BOUNDARY BUT
SOMEWHAT HIGHER DEW POINT TEMPERATURES TO THE SOUTH.
SURFACE TEMPERATURES STARTING OUT IN THE LOW TO MID 70S UNDER A SOLID
SHIELD OF CIRRUS ASSOCIATED WITH T.S.CINDY.

CURRENT OHX 88D SHOWS AREA OF LIGHT RAIN ACROSS WESTERN TENNESSEE
DISSIPATING AS IT MOVES SLOWLY EAST.

WILL LIKELY UPDATE TO INCREASE CLOUD COVER ACROSS THE BOARD AND
POSSIBLY ADD POPS INTO NW ZONES.

.OHX WATCHES/WARNINGS/ADVISORIES...NONE.
