.UPDATE...
ISSUED AT 1022 AM EDT THU JUN 13 2013

THREAT FOR DAMAGING WINDS AND LARGE HAIL WILL CONTINUE UNTIL MID
AFTERNOON. RAPIDLY EVOLVING SITUATION THIS MORNING AS SHORT WAVE
TROF AND VORT MAX OVER INDIANA DIVES ESE. CURRENT DATA INDICATES TROF
AXIS AND VORT MAX MOVING ACROSS E KY AROUND 18Z. WHEN THIS PASSES TO
OUR SOUTHEAST BY MID AFTERNOON THE SEVERE THERAT WILL END. A LINE OF
CONVECTION HAS DEVELOPED IN RESPONSE TO THE FORCING WITH THE TROF AND
VORT CENTER...AND HAS BEEN PROGESSING STEADILY SOUTHEAST THROUGH THE
MORNING...JUST NOW NEARING FLEMING COUNTY. EXPECT INTENSIFICATION OF
LINE AS IT CONTINUES MOVING SOUTHEAST INTO MOIST UNSTABLE
ENVIRONMENT. SHOULD ALSO SEE SOME INTERACTION WITH BOUNDARY LEFT
ACROSS THE CENTER PART OF THE FORECAST AREA FROM SCATTERED EARLY
MORNING CONVECTION. UPDATED NDFD AND ASSOCIATED PRODUCTS.

UPDATE ISSUED AT 755 AM EDT THU JUN 13 2013

SOME ISOLATED TO SCATTERED SHOWERS AND EVEN A THUNDERSTORM ARE
WORKING ACROSS THE CENTRAL PART OF THE CWA ATTM. HOWEVER...THIS HAS
BEEN RATHER TAME OVERALL. ADDITIONAL CONVECTION CONTINUES TO DEVELOP
OVER CENTRAL AND SOUTHERN INDIANA AND THIS AND THE UPPER LEVEL
DISTURBANCE SHOULD WORK INTO EASTERN KY LATER THIS MORNING INTO THE
EARLY AFTERNOON. HOURLY POPS WERE ADJUSTED TO PUSH BACK THE HIGHEST
POPS A COUPLE OF HOURS ON AVERAGE TO TIME IN ACTIVITY NOW OVER
INDIANA. A FEW MINOR CHANGES WERE ALSO MADE TO THE HOURLY
TEMPERATURES AND DEWPOINTS.

.SHORT TERM...(TODAY THROUGH FRIDAY)
ISSUED AT 345 AM EDT THU JUN 13 2013

A SFC LOW IS CURRENTLY TRACKING EAST ACROSS THE SOUTHERN GREAT LAKES
REGION IN ADVANCE OF RATHER POTENT SHORTWAVE TROUGH MOVING ACROSS THE
WESTERN GREAT LAKES. THIS SYSTEM HAS NOT AS OF YET MERGED WITH A
TROUGH TO ITS NORTH WORKING ACROSS ONTARIO INTO QUEBEC...BUT THIS
SYSTEM SHOULD PHASE WELL TO OUR EAST ACROSS THE MID ATLANTIC STATES
LATER TODAY AND INTO TONIGHT WITH THE SHORTWAVE TROUGH BEING REPLACED
LOCALLY BY HEIGHT RISES. FROM LATE TODAY THROUGH THE END OF THE PERIOD...
RIDGING NOW OVER THE PLAINS STATES WILL BUILD EAST INTO THE CENTRAL
CONUS AND BECOME CENTERED OVER THE ARKLATEX REGION BY THE END OF THE
PERIOD. MEANWHILE....THE SFC LOW WILL TRACK EAST INTO THE MID
ATLANTIC STATES NEAR THE INTERSTATE 80 CORRIDOR AND THEN REDEVELOP
INTO A RATHER POTENT MID LATITUDE CYCLONE FOR JUNE AS IT MOVES OFF
THE MID ATLANTIC COAST AND INTO THE ATLANTIC.

CONVECTION SO FAR OVERNIGHT HAS BEEN MAINLY CONFINED TO LOCATIONS
TO OUR NORTH AND NORTHWEST CLOSER TO THE WARM FRONT OVER OH...IL AN
IN. A FEW SHOWERS HAVE RECENTLY DEVELOPED A BIT FURTHER TO THE
SOUTH AND WEST CLOSER TO THE OH RIVER OVER SE IN...SOUTHWEST OH AND
NORTH CENTRAL KY...BUT HAVE NOT AMOUNTED TO MUCH. AN INITIAL CLUSTER
WAS WORKING TOWARD THE OH RIVER...TOWARD THE WV AND OH BORDER WITH
ADDITIONAL CONVECTION IN CENTRAL INDIANA.

THE CONVECTION NEARING THE OH/WV BORDER IS HEADING MORE OR LESS EAST
SOUTHEAST AND INTO WV AND SHOULD LARGELY NOT AFFECT THE JKL CWA.
HOWEVER...OUTFLOW BOUNDARIES FROM THIS INITIAL CONVECTION AND
CONVECTION NOW OVER IN OR THE CONVECTION OVER INDIANA ITSELF SHOULD
REACH THE LOCAL AREA AROUND OR AFTER DAWN. THIS...AND THE APPROACH OF
THE SHORTWAVE TROUGH AND COLD FRONT SHOULD PROVIDE ENOUGH LIFT TO
BREAK THE CAP CURRENTLY IN PLACE OVER EAST KY. GIVEN EXPECTED SHEAR
AND RATHER STRONG WINDS ALOFT AS WELL AS ELEVATED OR SFC INSTABILITY
CONVECTION AROUND DAWN AND INTO THE DAY ON THU COULD BE SEVERE WITH
DAMAGING WIND GUSTS AND HAIL THE PRIMARY THREATS. THE THREAT FOR ANY
SEVERE THUNDERSTORMS SHOULD DIMINISH FROM NW TO SE FROM MID TO LATE
MORNING THROUGH AFTERNOON AS THE COLD FRONT AND THE SHORTWAVE TROUGH
AXIS MOVES EAST OF THE AREA AND THE COLD FRONT DROPS SOUTHEAST INTO
VA AND TN. IN FACT...DEEPER MOISTURE AND LIFT SHOULD EXIT TO THE
SOUTHEAST EARLY ENOUGH THAT DRY WEATHER IS ANTICIPATED FROM LATE
EVENING INTO THE OVERNIGHT HOURS TONIGHT ACROSS ALL OF EAST KY.

HEIGHT RISES AND ASSOCIATED SFC HIGH PRESSURE BUILDING INTO THE OH
VALLEY REGION AND APPALACHIANS WILL BRING DRY WEATHER AND A COLDER
AND MUCH DRIER AIRMASS TO END THE SHORT TERM PERIOD.

AS FOR POPS...ALTHOUGH THIS IS A LOWER THAN NORMAL CONFIDENCE
FORECAST...WENT WITH LIKELY POPS SHORTLY AFTER DAWN FOR THE
NORTHWEST COUNTIES AND THEN TRANSITIONED THIS TO THE SOUTH AND EAST
THROUGH EARLY AFTERNOON FOR THE ANTICIPATED PREFRONTAL LINE OF
CONVECTION SOME OF WHICH MAY BE SEVERE. OPTED FOR PERSISTENCE OF
POTENTIAL FOR DAMAGING WINDS AND LARGE HAIL IN THE GRIDS AS WELL.
CONVECTION AND CLOUD COVER SHOULD LEAD TO A RATHER LIMITED DIURNAL
RISE FOR TODAY AND DAYTIME MAX TEMPS SHOULD NOT BE FAR FROM CURRENT
READINGS IN MANY LOCATIONS...WITH THE CURRENTLY DECOUPLED DEEPER
VALLEYS GETTING SCOURED OUT AS THE PRESS GRADIENT INCREASES.

LOWS TONIGHT...EXPECTED TO BE IN THE MID TO UPPER 50S...ALTHOUGH
ONLY ON THE ORDER OF ABOUT 5 DEGREES BELOW NORMAL WILL ON AVERAGE BE
10 TO 15 DEGREES BELOW READINGS FROM THIS MORNING. LINGERING LOW
LEVEL MOISTURE FROM TODAY/S ANTICIPATED CONVECTION AND A DECREASING
GRADIENT SHOULD LEAD TO SOME PATCHY VALLEY FOG LATER TONIGHT DESPITE
ADVECTION OF DRIER AIR. THE COLDER AIRMASS SHOULD LEAD TO HIGHS ONLY
IN THE UPPER 70S TO AROUND 80 ON AVERAGE ON FRIDAY OR A FEW DEGREES
BELOW NORMAL...OFFERING RELIEF FROM THE RECENT MID WEEK HEAT AND
HUMIDITY.

.LONG TERM...(FRIDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 327 AM EDT THU JUN 13 2013

TROUGHING ALOFT TO OUR EAST WILL REMAIN PERSISTENT THROUGH THE
PERIOD LEAVING US IN A NORTHWEST FLOW PATTERN. WHILE SATURDAY LOOKS
DRY...RIPPLES PASSING BY IN THE MEAN FLOW WILL BRING RENEWED CHANCES
FOR SHOWERS/STORMS BY SUNDAY. ONE SHORTWAVE IN PARTICULAR WILL BE
STOUT ENOUGH TO FORCE A COLD FRONT INTO AND THROUGH OUR REGION FROM
SUNDAY NIGHT THROUGH MONDAY NIGHT. THIS APPEARS TO BE OUR BEST SHOT
AT RAIN. THE FRONT IS PROGGED TO SETTLE TO OUR SOUTH TUESDAY INTO
TUESDAY NIGHT WITH DWINDLING RAIN CHANCES THE RESULT. TEMPERATURES
FOR THE PERIOD ARE EXPECTED TO REMAIN PRETTY CLOSE TO NORMAL WITH
HIGHS IN THE 80S AND LOWS STARTING OUT IN THE 50S ON FRIDAY NIGHT
BUT MODERATING INTO THE 60S FOR THE REST OF THE PERIOD.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z FRIDAY MORNING)
ISSUED AT 755 AM EDT THU JUN 13 2013

AS A COLD FRONT AND AN UPPER LEVEL DISTURBANCE PASSES THROUGH THE REGION
TODAY...SHOWERS AND THUNDERSTORMS SHOULD WORK ACROSS THE REGION...MAINLY
AFTER 14Z THROUGH ABOUT 19Z. HOWEVER...A THUNDERSTORM IS POSSIBLE
INITIALLY MAINLY NEAR JKL. STORMS THAT OCCUR DURING THIS PERIOD WILL
HAVE POTENTIAL FOR STRONG OR DAMAGING WINDS AND HAIL. AS USUAL...IFR
OR LOWER CAN BE EXPECTED IN THE HEAVIER SHOWERS AND STORMS. OTHERWISE...
VFR SHOULD PREVAIL OUTSIDE OF CONVECTION EXCEPT PERHAPS SOME IFR OR
LOWER FOG LATE IN THE PERIOD BETWEEN 6Z AND 12Z IN VALLEY LOCATIONS
SUCH AS LOZ AND SME.
