The radar

The Ft Campbell radar (KHPX), 17 km from the middle of the area, began a volume at 19:30 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, 7.5 hours before the alert went out and 82 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.

NWS Nashville, TN wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 23, 12:08 PM CDT, 2 hours 23 minutes earlier.

Area forecast discussion, Jun 23, 12:08 PM CDT, 2 hours 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
1208 PM CDT MON JUN 23 2014

.UPDATE...ADDED AVIATION SECTION FOR 18Z TAF'S.

&&

.AVIATION...BNA/CKV/CSV...SCATTERED CONVECTION ALREADY FIRING
ACROSS MIDDLE TENNESSEE, WITH THE AIR MASS REMAINING RELATIVELY
MOIST AND VERY UNSTABLE. EXPECT CONVECTION TO DIE OFF TOWARD
EVENING, WITH LIGHT FOG POSSIBLE OVERNIGHT.

&&

.PREV DISCUSSION... /ISSUED 626 AM CDT MON JUN 23 2014/

UPDATE...
WILL BE UPDATING THE SUITE OF FORECAST PRODUCTS AS ISO SHWRS/TSTMS HAVE
DEVELOPED ACROSS SW PORTIONS OF THE MID STATE IN ASSOCIATION WITH BEST
MOISTURE AND INSTABILITY AXIS...AND BELIEVE THEY WILL EXITS ACROSS THESE
AREAS DURING THE REMAINDER OF THE MORNING HOURS. ALSO...WITH OBS
SITES NOT REPORTING ANY TREND TOWARD PATCHY DENSE FOG...REMOVED THE
SPECIAL WEATHER STATEMENT CONCERNING PATCHY LOCALLY DENSE FOG. WILL
KEEP THE MENTION THOUGH OF PATCHY FOG IN THE FORECAST THROUGH 14Z.

PREV DISCUSSION.../ISSUED 512 AM CDT MON JUN 23 2014/

AVIATION 12Z DISCUSSION...
PATCHY FOG WILL PLAGUE THE FIRST 2 HOURS OF THE UPCOMING TAF PD.
PCLDY SKIES SHOULD THEN PREVAIL. OTHERWISE...A MID/UPPER LEVEL SHORTWAVE
IS EXPECTED TO APPROACH...WITH RAIN CHANCES ON THE INCREASE
THROUGH THE TAF PD. WILL UTILIZE VCNTY FOR THIS AFTERNOON BUT WILL
EXPAND TO TEMPO GROUPS TOWARD THE END OF THE TAF PD.

PREV DISCUSSION... /ISSUED 344 AM CDT MON JUN 23 2014/

DISCUSSION...
FORECAST QUANDARIES...POTENTIAL FOR PATCHY LOCALLY DENSE FOG THRU
THE MID MORNING HRS TODAY...SHWR/TSTM CHANCES...TEMPS.

DO NOT EXPECT IT TO BE OVERALL AS PATCHY OF A DENSE FOG SITUATION
AS IT WAS AT THIS TIME YESTERDAY MORNING...BUT HAVE GOT SOME
OBSERVATIONS OVER THE LAST COUPLE OF HOURS SHOWING A TREND TOWARD
PATCHY DENSE FOG DEVELOPMENT MAINLY NEAR BODIES OF WATER AND OTHER
LOW LYING LOCATIONS PER THE LATEST SFC OBS AND SATELLITE TRENDS...AND
WITH WIDESPREAD DEWPOINT DEPRESSIONS ACROSS THE MID STATE LESS THAN
FIVE DEGREES AND WITH CALM WINDS MOST LOCATIONS...STILL BELIEVE THAT
AREAS EXPERIENCING SIGNIFICANT BREAKS IN SCT/BKN CI COVERAGE COULD
SUPPORT PATCHY FOG...WITH SOME LOCALLY DENSE POSSIBLE. NOT ANTICIPATING
AS OF THIS TIME ENOUGH COVERAGE TO WARRANT A DENSE FOG ADVISORY...BUT
DID ISSUE EARLIER THIS MORNING A SPECIAL WX STATEMENT DEALING WITH
PATCHY DENSE FOG POTENTIAL THRU THE MID MORNING HRS TODAY.

OTHERWISE...IN GENERAL AGREEMENT WITH LATEST WPC MODEL DIAGNOSTIC
DISCUSSION IN POINTING OUT THE CONSISTENCIES OF THE EURO SOLUTION AS
OF LATE WITH THIS DIRTY RIDGE PATTERN BEING EXPERIENCED ACROSS THE
MID STATE AND HOW IT HAS CONSISTENTLY DEPICTED THE EXPECTED WX OVER
THE NEXT SEVERAL DAYS...AND THUS WILL LEAN ACCORDINGLY. BELIEVE
THAT SHWR/TSTM CHANCES WILL INCREASE AS THE DAY PROGRESSES...WITH
DIURNAL INFLUENCES KICKING IN DURING THE AFTERNOON HRS SUPPORTING
SCT SHWRS/TSTMS ACROSS THE ENTIRE MID STATE...WITH BEST COVERAGE
FOR LOCATIONS APPROACHING THE TN/AL BORDER...AS UPPER RIDGING
INFLUENCES RETROGRADES INTO THE WRN GULF OF MEXICO AND SFC FRONT
CURRENTLY BISECTING THE MID STATE FROM THE NW TO SE JUST E OF THE
I-24 CORRIDOR...PUSHES EWD WITH MOST OF THE MID STATE IN THE WARM
SECTOR OF A BROAD SFC FRONTAL SYSTEM APPROACHING THE MID MS VALLEY
AS THE DAY PROGRESSES. AS FOR TEMPS...GFS MOS HAS HAD A TENDENCY
AS OF LATE TO BE A LITTLE COOL ON THE HIGHS...OTHER THAN YESTERDAY...
AND WITH A CONTINUANCE OF SLY FLOW EXPECTED...WILL GO A DEGREE OR
TWO ABOVE GUIDANCE VALUES HERE. THOUGH I AM FAVORING THE EURO SOLUTION
AS A WHOLE...IT IS GENERALLY THE COOLEST SOLUTION IN COMPARISON TO
THE GFS/NAM ON MANY OCCASIONS...AND THUS WILL TWEAK ITS TEMPS UP
HERE IN THIS CASE FOR TODAY.

WILL GO WITH INCREASING CHANCES OF SHWRS/TSTMS AS THE NIGHTIME
PROGRESSES AS SFC SYSTEM AND UPPER LEVEL TROUGHING APPROACH THE MID
STATE WITH LOWS MAINLY IN THE UPPER 60S TO AROUND 70. BEST CHANCE
OF RAIN LOOKS TO BE ON TUE PER SHORTWAVES IN UPPER LEVEL TROUGH
PASSAGE...WITH DEF SHWRS/TSTMS BY THE AFTERNOON HRS...WITH PRECIP
WATER VALUES IN SOME LOCATIONS APPROACHING TWO INCHES. WOULD
NOT BE SURPRISED THAT SOME LOCATIONS DURING THE AFTERNOON HRS
EXPERIENCE HEAVY RAINFALL...BUT BELOW EXPECTED FFG VALUES AS OF
THIS TIME. WITH ADDITIONAL CLOUD COVERAGE EXPECTED ALSO...WILL
GO WITH HIGHS SPANNING THE 80S. AS UPPER LEVEL TROUGHING CHARACTERISTICS
BEGIN TO WEAKEN...BUT SFC FRONT APPROACHES MID STATE...WILL GO WITH
LIKELY SHWRS/TSTMS TUE EVENING...WITH A CHANCE OF SHWRS/TSTMS TUE NIGHT
WITH LOWS AGAIN IN THE UPPER 60S TO LOWER 70S. WITH SFC FRONT PUSHING
E OF THE MID STATE ON WED...AND A MORE OF A ZONAL FLOW PATTERN ACROSS
THE MID STATE...WILL GO WITH A CHANCE OF SHWRS/TSTMS WITH HIGHS IN
THE MID 80S...UPPER 70S TO LOWER 80S PLATEAU.

TAKING A LOOK AT THE REST OF THE WEEK INTO NEXT WEEKEND...UPPER LEVEL
PATTERN WILL CONTINUE TO SUPPORT PASSAGES OF SHORTWAVES IN FLOW ALOFT
WITH A CHANCE OF SHWRS/TSTMS THRU FRI WITH TEMPS AGAIN APPROACHING 90
DEGREES...MID TO UPPER 80S PLATEAU. AS SFC AND UPPER LEVEL HIGH
PRESSURE INFLUENCES BECOME BETTER ESTABLISHED AGAIN ACROSS THE SE
U.S. FOR THIS UPCOMING WEEKEND...PRECIP WATER VALUES WILL DROP...BUT
CAN CERTAINLY NOT RULE OUT A SLIGHT CHANCE OF SHWRS/TSTMS OVER THE
WEEKEND AS THE OVERALL DIRTY RIDGE PATTERN THE MID STATE HAS BEEN
EXPERIENCING AS OF LATE REESTABLISHES ITSELF ACROSS THE AREA WITH
HIGHS CONTINUING TO BE IN THE UPPER 80S TO AROUND 90...MID 80S
PLATEAU.

THRU THIS ENTIRE FORECAST PERIOD ALSO...WOULD NOT BE SURPRISED...AS
IT USUALLY HAPPENS DURING THE SUMMER MONTHS WITH AN OVERALL PATTERN
LIKE THIS...THAT SOME TSTMS REACH STRONG THRESHOLDS...WITH AN
ISOLATED SVR TSTMS DEVELOPING HERE OR THERE...MAINLY DURING THE
AFTERNOON THRU EARLY EVENING HRS...WITH STRONG TO DAMAGING WINDS AND
BRIEF HEAVY RAINFALL POSSIBLE...BUT AM NOT EXPECTING ANY ORGANIZED
WIDESPREAD SVR TSTM POTENTIAL AS OF THIS TIME. THIS REASONING ALSO
SUPPORTED BY THE LATEST SUITE OF SPC CONVECTIVE OUTLOOK PRODUCTS.

&&

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