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 12:00Z, 7.8 hours before the alert went out and 68 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, Jul 27, 2:39 PM CDT, 8 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
239 PM CDT WED JUL 27 2005

.DISCUSSION...
A COLD FRONT WAS MAKING ITS WAY INTO MIDDLE TENNESSEE. THE FRONT
EXTENDED FROM WESTERN PENNSYLVANIA, ACROSS CENTRAL KENTUCKY,
WESTERN MIDDLE TENNESSEE, AND INTO CENTRAL ARKANSAS. AHEAD OF THE
FRONT, A LINE OF STRONG THUNDERSTORMS DEVELOPED AROUND NOON AND
CONTINUES TO MOVE EAST ACROSS MIDDLE TENNESSEE. ALONG AND BEHIND
THE FRONT, SHOWERS AND THUNDERSTORMS STRETCHED ALONG THE OHIO
RIVER SOUTHWEST ACROSS THE BOOTHEEL OF MISSOURI, AND THROUGH
CENTRAL ARKANSAS. TO THE WEST...A LARGE AREA OF HIGH PRESSURE WAS
CENTERED OVER THE CENTRAL PLAINS EXTENDING OVER MOST OF THE
CENTRAL U.S. LOCALLY...ACROSS MIDDLE TENNESSEE WINDS HAD SHIFTED TO
NORTHWEST ACROSS THE NORTHWEST PORTION OF THE MID STATE WHILE
SOUTHWEST WINDS CONTINUED ACROSS THE SOUTHEAST. TEMPERATURES
DROPPED NEARLY 15 DEGREES AS THE SHOWERS AND THUNDERSTORMS PASSED
THROUGH NASHVILLE. FINALLY SOME RELIEF FROM THE HEAT

.FORECAST...
THE COLD FRONT WILL USHER IN MUCH ANTICIPATED COOLER AIR WHICH
WILL SETTLE INTO THE TENNESSEE VALLEY DURING THE SECOND HALF OF
THE WORK WEEK. AS THE FRONT PUSHES THROUGH, SHOWERS WILL END ACROSS
ALL BUT SOUTHEAST MIDDLE TENNESSEE BY THURSDAY EVENING. AN AREA
OF LOW PRESSURE IS FORECAST TO DEVELOP ACROSS ALABAMA ON FRIDAY
WHICH WILL INTERACT WITH THE FRONT AND KEEP A CHANCE OF SHOWERS
ACROSS THE SOUTHEAST THROUGH SATURDAY MORNING.

ALOFT...THE UPPER RIDGE HAD RETROGRADED AS A SIGNIFICANT TROUGH
MOVED THROUGH THE WESTERLIES AND LOWERED HEIGHTS ACROSS THE OHIO
AND TENNESSEE VALLEYS. MODELS INDICATE THIS PATTERN WILL PERSIST
THEREFORE...EXPECT A RETURN TO NEAR NORMAL TEMPERATURES AND
HUMIDITY LEVELS THROUGH THE FORECAST PERIOD.
