The radar

The Northeast Alabama radar (KHTX), 114 km from the middle of the area, began a volume at 16:44 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 12:00Z, 4.7 hours before the alert went out and 115 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
1000 AM CDT TUE OCT 19 2004

.DISCUSSION...MY FIRST THOUGHT AFTER COMING ON DUTY WAS THAT POPS
MIGHT BE A LITTLE TOO HIGH OVER THE NORTHERN AREAS OF THE MID STATE
FOR TODAY BUT LOOKS LIKE THEY MAY BE ON TARGET WITH ANOTHER ROUND OF
RAIN HEADED THIS WAY. SURFACE DEWPOINT AXIS RUNNING RIGHT UP ALONG THE
MISSISSIPPI RIVER. ALSO SATELLITE LOOP SHOWING SOUTHERN STEAM JET MAX
PUNCHING ACROSS TEXAS THIS MORNING. LEFT FRONT QUAD SEEMS TO BE WHERE
MUCH OF PRECIP IS GETTING GENERATED OVER NORTH MISSISSIPPI AND WESTERN
TENNESSEE. CANT RULE OUT SEVERE STORMS THIS AFTERNOON...ESPECIALLY
OVER THE SOUTHERN AREAS CLOSER TO SPEED MAX.

NO CHANGES AT THIS TIME TO ZONES.
