The radar

The Northeast Alabama radar (KHTX), 77 km from the middle of the area, began a volume at 19:12 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 12:00Z, 7.2 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.

.UPDATE...FOR AVIATION.

.AVIATION...
18Z TAFS...MAINLY MVFR CIGS/VSBYS THROUGH THE REST OF TODAY WITH
SCT SHRA/TSRA. LOTS OF LOW LEVEL MOISTURE WILL REMAIN IN PLACE
OVERNIGHT LEADING TO WIDESPREAD STRATUS/FOG. EXPECT WIDESPREAD IFR

.PREV DISCUSSION... /ISSUED 942 AM CDT MON JUN 1 2015/

UPDATE...THE BAND OF DEEP MOISTURE THAT HAS PRODUCED WIDESPREAD
SHOWERS NE OF I-24 THIS MORNING WILL CONTINUE TO LIFT NE...OUT OF
MID TN BY LUNCHTIME. PLENTY OF LOW LEVEL MOISTURE WILL REMAIN AS
AN UPPER LEVEL LOW PRESSURE SYSTEM OVER THE MO BOOTHEEL MOVES
SLOWLY EASTWARD. THIS UPPER LEVEL LOW...ALONG WITH A QUASI
STATIONARY SURFACE FRONT OVER THE PLATEAU...WILL HELP INITIATE
SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THE DAY. COOLER AIR
ALOFT WITH THE LOW...AND DRIER AIR AT MID LEVELS...WILL BRING THE
POTENTIAL FOR A FEW STRONG TO MARGINALLY SEVERE STORMS WITH
LOCALIZED GUSTY WINDS. ON THE OTHER HAND...FAIRLY THICK LOW CLOUDS
WILL LIMIT SURFACE DESTABILIZATION. IT LOOKS LIKE THE GREATEST
CHANCE FOR STORMS WILL GUSTY WINDS WILL BE OVER THE PLATEAU. SOME
OF THE STORMS MAY CONTAIN LOCALIZED DOWNPOURS...RESULTING IN SOME
PONDING WATER...BUT WE DO NOT EXPECT ANY MAJOR OR WIDESPREAD
FLOODING PROBLEMS. EXTENSIVE CLOUDS AND SCATTERED SHOWERS WILL LIMIT
TEMPERATURES TO THE LOW TO MID 70S. UPDATES HAVE ALREADY BEEN
ISSUED TO ADDRESS HOURLY TRENDS...AND THE FORECAST WILL CONTINUE TO
BE FRESHENED AS THE FIRST WAVE OF SHOWERS MOVES OUT OF THE AREA.

DISCUSSION...
NEEDLESS TO SAY TROPOSPHERE IS JUICED UP WITH PRECIPITABLE WATER OFF
LAST NIGHTS 00Z OHX RAOB INTEGRATED SURFACE TO 500 MBAR AT 1.63 INCHES.
GOOD ROUND OF SHOWERS AND ISOLATED THUNDERSTORMS CURRENTLY CONCENTRATED
ALONG THE PLATEAU...WILL CONTINUE TO ADVANCE NORTHWARD AND INTO
KENTUCKY BY 12Z. THIS AREA HAS NOT RECEIVED MUCH RAINFALL DURING
THE LAST SEVERAL DAYS SO COULD HANDLE A LITTLE. 3 HOUR GUIDANCE
VALUES ALONG THE PLATEAU ON THE ORDER OF 2.5 TO 3 INCHES. AS WE GO

ALOFT UPPER TROUGH DOMINATING EASTERN HALF OF U.S WITH CUTOFF LOW
OVER ARKANSAS AT 06Z. CUTOFF LOW MUCH FARTHER NORTH THAN WHAT THE
MODELS ADVERTISED 24 HOURS AGO. UPPER LOW CRAWLS EASTWARD AND INTO
MIDDLE TENNESSEE BY 12Z TUESDAY. ONGOING SHOWERS THIS MORNING
ACROSS MIDDLE TENNESSEE AND ISOLATED THUNDERSTORMS ALONG THE
PLATEAU WILL CONTINUE WITH THE HIGHEST POPS NORTH AND EAST OF
INTERSTATE 24 DURING THE DAY. TONIGHT LOOK FOR SHOWERS AND
ISOLATED THUNDERSTORMS A LITTLE MORE NUMEROUS IN EASTERN AREAS. ON
WEDNESDAY UPPER LOW WILL BE SITTING RIGHT OVER THE PLATEAU SO HAVE
THE HIGHER POPS IN EASTERN AREAS AND ALONG THE PLATEAU...WITH
SURFACE FRONT IN EASTERN TENNESSEE BEFORE WASHING OUT. UNSETTLED

AVERAGE 3 TO 5 DEGREES ABOVE THE 30 YEAR NORMALS FOR THIS TIME OF
THE YEAR...WITH SEVERAL NIGHTTIME LOWS IN THE MIDDLE 60S.
