AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
1213 AM CDT THU JUN 5 2014

.AVIATION 06Z DISCUSSION...
MCS IS WEAKENING AS IT CONTINUES TO MOVE SOUTHWARD THROUGH THE MID
STATE. NONETHELESS...CONVECTION IS LIKELY FOR THE FIRST FEW HOURS
OF THE TAF PD. TEMPORARY WIND GUSTS OF 35 MPH CAN BE EXPECTED
EARLY ON. CONVECTION SHOULD CLEAR THE TERMINAL AREAS BY 10Z OR SO
WITH JUST VCSH AND SOME LOWER CIGS THEREAFTER UNTIL 14Z.

THU AFTERNOON THE BETTER INSTABILITY AXIS WILL SHIFT SOUTHWEST OF
THE TERMINALS. WILL STILL INCLUDE A VCNTY QUALIFIER FOR A FEW
HOURS.

&&

.PREV DISCUSSION... /ISSUED 1105 PM CDT WED JUN 4 2014/

UPDATE...
AS MENTIONED EARLIER THIS EVENING...THIS WHOLE SYSTEM LOOKED
RATHER IFFY IN TERMS OF SEVERE. STORMS ARE NOW WEAKENING IN INTENSITY.
THE COVERAGE IS NOW ACROSS OUR FAR NORTHERN TIER OF COUNTIES.
BUT...ISOLATED AREAS OF 40-50 MPH WIND GUSTS CAN STILL BE
EXPECTED. WILL STILL ALLOW THE WATCH TO CONTINUE FOR A LITTLE
WHILE LONGER...CANT COMPLETELY RULE OUT THE POTENTIAL FOR SOME
STRENGTHENING TO OCCUR BUT HELICITY VALUES LOOK TO BE DECREASING
SLOWLY. OTW...ILL ADJUST THE WEATHER GRIDS AND LOWER SOUTHERN
AREAS TO A CHANCE PRIOR TO MIDNIGHT. SHORT DURATION HEAVY RAIN
THREAT FOR SOME OF THE STRONGER CONVECTION STILL EXISTS BUT NO
REAL FLOOD THREAT IS INDICATED. LIKELY POPS WILL BE INCLUDED FOR
THE AFTER MIDNIGHT PERIOD. CATEGORICAL POPS FAR NORTH PRIOR TO
THAT TIME.

PREV DISCUSSION... /ISSUED 840 PM CDT WED JUN 4 2014/

UPDATE...
HEAVY RAINFALL APPEARS TO BE MASSING ACROSS WESTERN PORTIONS OF
KY. 1 TO 3 INCH RAINFALL TOTALS ARE LOOKING MORE AND MORE LIKELY
ACROSS THE NORTHERN PORTIONS OF THE MID STATE. JUST POPULATED WITH
THE LATEST HPC QPF GUIDANCE AND IT DOES INDEED JACK UP OUR QPF
FOR THE OVERNIGHT. HOWEVER...FFG LOOKS SAFE AT THIS POINT AND A
WIDESPREAD FLOOD EVENT IS NOT EXPECTED. WILL GO AHEAD AND ADD THE
POTENTIAL FOR HEAVY RAINFALL IN THE GRIDS. THE HEAVIER RAINFALL
THREAT WILL MOVE INTO OUR SOUTHERN COUNTIES AFTER MIDNIGHT SO I
WILL INCLUDE THAT AS WELL.

OTHERWISE...TORNADO WATCH CONTINUES. 2 SEVERE CELLS ARE NOTED ON
RADAR. ONE IS SOUTHEAST OF BOWLING GREEN AND THE OTHER NORTH OF
HOPKINSVILLE. BOTH OF THESE WILL TRANSLATE EAST SOUTHEAST AND THE
CONVECTION SHOULD REACH OUR NORTHERN MOST COUNTIES BETWEEN 9 PM
AND 11 PM. LAPS HELICITY VALUES DO INCREASE SOME AS WE MOVE TOWARD
OUR PLATEAU.

UPDATE OUT SHORTLY.

PREV DISCUSSION... /ISSUED 708 PM CDT WED JUN 4 2014/

UPDATE...FOR 00Z AVIATION DISCUSSION.

AVIATION...00Z AVIATION DISCUSSION.
LOOKING FOR OVERALL BEST CHANCE OF SHWRS/TSTMS ASSOCIATED WITH
DEVELOPING MCS TO IMPACT TAF SITES 05/02Z-05/05Z CKV...05/03Z-05/06Z
BNA...TO 05/05Z-05/08Z...WITH SOME CONVECTIVE GUSTS TO 40KTS ALSO
POSSIBLE. SOME HEAVY RAINFALL EXPECTED WITH THIS BEST WINDOW OF

MESOSCALE UPDATE...FINAL THOUGHTS
LINE OF CONVECTION FROM JUST SOUTH OF SAINT LOUIS EASTWARD ACROSS
SOUTHERN ILLINOIS INTO SOUTHWEST INDIANA. ELEVATED MIXED LAYER FROM

MIDDLE TENNESSEE AT 20Z. 35-40 KNOT 850 MBAR JET PUNCHING UP ALONG

THIS IN AREA OF TORNADO WATCHES. PRECIPITABLE WATER CLOSE TO 2 INCHES
WILL ADVECT SOUTHEASTWARD TONIGHT FROM SOUTHEASTERN MISSOURI INTO
MIDDLE TENNESSEE. ONCE THE INITIAL LINE OF CONVECTION ARRIVES HERE IN
MIDDLE TENNESSEE THIS EVENING IT WILL BE FOLLOWED BY SIGNIFICANT
RAINFALL POSSIBLY FOR SEVERAL HOURS AT SOME LOCATIONS IN THE MID
STATE THAT COULD LEAD TO FLASH FLOODING. THIS IN ADDITION TO THE
THREAT FOR DAMAGING WINDS WITH THE INITIAL LINE OF CONVECTION. ARRIVAL
TIMES IN PREVIOUS DISCUSSION STILL ON TRACK.
