The radar

The Northeast Alabama radar (KHTX), 97 km from the middle of the area, began a volume at 09:57 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 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 00:00Z, 9.9 hours before the alert went out and 95 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 Oct 19, 3:21 AM CDT, 1 hour 33 minutes earlier.

Area forecast discussion, Oct 19, 3:21 AM CDT, 1 hour 33 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
321 AM CDT TUE OCT 19 2004

.DISCUSSION...SURFACE MAP FROM 07Z HAS 1004 MB LOW CENTERED OVER
SOUTHEAST MISSOURI, WITH WARM FRONT STRETCHED ACROSS THE OHIO
VALLEY, AND A COLD FRONT EXTENDING WESTWARD INTO THE SOUTHERN
PLAINS. OVER MIDDLE TENNESSEE, WE ARE GETTING COPIOUS RAINFALL OVER
AREAS MAINLY SOUTH OF INTERSTATE 40, WITH NUMEROUS FLOODING REPORTS
COMING IN, ESPECIALLY FROM DAVIDSON COUNTY.

MODELS PUSH THE COLD FRONT THROUGH MIDDLE TENNESSEE TONIGHT, WITH
THE GFS RUNNING ABOUT 6 HOURS FASTER THAN THE NGM. BELIEVE MOST OF
THE WEATHER WILL HAVE MOVED OUT OF THE MID STATE LONG BEFORE THE
FRONTAL PASSAGE, ALTHOUGH WILL LEAVE IN SOME POPS IN CASE MORE
WEATHER DEVELOPS ALONG THE FRONT. EITHER WAY, OUR WEATHER SHOULD
START TO IMPROVE BY WEDNESDAY, WITH PRECIPITATION EFFICIENCY MACROS
SHOWING LITTLE CHANCE FOR MORE RAIN UNTIL SATURDAY WITH THE APPROACH
OF THE NEXT SURFACE SYSTEM.

UNTIL THEN, LOOK FOR TEMPERATURES TO MODERATE IN THE 50S/70S THROUGH
THE FORECAST PERIOD, WHICH WILL PUT US SEVERAL DEGREES ABOVE NORMAL.

.BNA WATCHES/WARNINGS/ADVISORIES...TORNADO WATCH MOST OF MIDDLE
TENNESSEE UNTIL 400 AM.
