HRRR EVEN SUGGESTS POSSIBLE ORGANIZED CONVECTION MOVING FROM WEST TO EAST AFTER 18Z. ACTIVITY MAY LAST INTO THE EVENING ACROSS THE CUMBERLAND PLATEAU, WITH FOG POSSIBLE AT CKV AND CSV OVERNIGHT. && .PREV DISCUSSION... /ISSUED 1119 AM CDT WED JUL 10 2013/ UPDATE... AIRMASS CONTINUES TO HEAT/DESTABILIZE LATE THIS MORNING...WITH DEWS HOLDING IN THE LOW/MID 70S. LATEST AVAILABLE MODELS SHOWING INSTABILITY HIGH END THIS AFTERNOON/EVENING...WITH SHEAR STAYING VERY MINIMAL. EFFECTIVE BULK SHEAR PROGGED TO STAY BELOW 20KT THROUGH THE LATE AFTERNOON. MODELS RAMPING UP CONVECTION AFT 17Z...WHICH WOULD BE EXPECTED GIVEN PARAMETERS. PRECIP WATER HANGING AROUND 2.0 SO DO EXPECT HEAVY DOWNPOURS...BUT STORMS SHOULD HAVE ENOUGH MOVEMENT TO LIMIT THREAT OF FLASH FLOODING. LARGE HAIL CHANCE ALSO SEEMINGLY SLIM WITH WETBULB ZERO/FREEZING LVL ROUGHLY 15KFT+ INTO LATE EVENING. RAISED POPS SOME NORTH/EAST FOR THE AFTERNOON. MAY MAKE VERY SMALL TEMP TWEAKS AS WELL.

AVIATION... 12Z TAFS...A FEW SHOWERS ARE DEVELOPING OVER THE PLATEAU REGION THIS MORNING...SO INCLUDING VCSH FOR CSV.

A FEW STRONG TSRA ARE EXPECTED WITH HEAVY DOWNPOURS AND LOCALLY GUSTY WINDS. AT LEAST SCT SHRA/TSRA WILL CONTINUE THROUGH TONIGHT AS THE FRONT MOVES SLOWLY ACROSS THE AREA. 13 PREV DISCUSSION... /ISSUED 328 AM CDT WED JUL 10 2013/ DISCUSSION...

STILL EXPECTING NWLY UPPER LEVEL FLOW PATTERN THAT IS BEING ESTABLISHED ACROSS THE MID STATE TO SEND SOME UPPER LEVEL DISTURBANCES DROPPING SE FROM THE MID MS AND OHIO RIVER VALLEYS TODAY. THIS WILL OCCUR AHEAD OF AN UNUSUAL ACTUAL PROGGED SUMMERTIME COLD FRONTAL PASSAGE...WHICH SHOULD BE APPROACHING WRN KY BY THE EVENING HRS...THEN CONTINUE MOVING SEWD AND MOVE INTO NW PORTIONS OF THE MID STATE BY EARLY THU MORNING. STILL ALSO EXPECT OVERALL INCREASED MOISTURE POOLING AHEAD OF THIS FRONTAL PASSAGE...WITH MODEL CONSENSUS STILL SHOWING PW'S AROUND TWO INCHES AS THE AFTERNOON HRS APPROACH AND INTO AT LEAST THE EVENING HRS TONIGHT...RESULTING IN THE POTENTIAL FOR NUMEROUS SHWRS AND TSTMS W TO SCT SHWRS/TSTMS E BY THIS AFTERNOON...WITH NUMEROUS SHWRS/TSTMS ALL LOCATIONS TONIGHT...SUPPORTING THE POTENTIAL OF BRIEF HEAVY RAINFALL. ALONG WITH THIS...DIURNAL INFLUENCES SHOULD KICK ENOUGH ALSO TO SUPPORT SOME STRONG TO POSSIBLY EVEN SVR TSTMS ACROSS LOCATIONS GENERALLY ALONG AND N OF I-40 AND ALONG AND W OF I-65. WILL MENTION THIS POSSIBILITY ALSO IN THIS MORNING'S HWO ISSUANCE. WITH POTENTIAL FOR MORE SHWRS/TSTMS NW...WILL UNDERCUT GFS MOS VALUES HERE BY A COUPLE OF DEGREES FOR HIGHS TODAY...OTHERWISE GO WITH MAINLY LOW 90S ACROSS THE MID STATE...WITH MID TO UPPER 80S PLATEAU. AS FOR TONIGHT...WITH ADDITIONAL CLOUD COVERAGE AND EXPECTED RAINFALL...WILL KEEP LOWS MAINLY IN THE LOWER 70S...UPPER 60S TO AROUND 70 PLATEAU. THIS COLD FRONT IS STILL EXPECTED TO PUSH S OF THE MID STATE DURING THE DAY ON THU...AND THUS WILL TAPER POPS OFF TO A SLIGHT CHANCE ACROSS NW PORTIONS OF THE MID STATE DURING THE MORNING HRS...WITH LIKELY POPS CONTINUING ACROSS ERN PORTIONS DURING THE MORNING HRS. WILL KEEP THE MENTION IN THIS MORNING'S HWO FOR LOCALLY HEAVY RAINFALL ACROSS ERN PORTIONS OF THE MID STATE TOO FOR THU MORNING. EXPECTING DRIER AIR TO HAVE WORKED ACROSS MOST OF THE MID STATE DURING THE AFTERNOON HRS...WITH GENERALLY A SLIGHT CHANCE OF SHWRS/TSTMS REMAINING ACROSS THE SRN 3RD OF THE MID STATE THU AFTERNOON. AFTERNOON HIGH TEMPS WILL BE SLIGHTLY COOLER THAN THOSE EXPECTED TODAY...WITH HIGHS MAINLY IN THE MID TO UPPER 80S. OTHER THAN SOME POSSIBLE EVENING ISO SHWRS/TSTMS PLATEAU ON THU NIGHT...THE MID STATE WILL BE DRY AS DRIER AIR CONTINUES TO WORK ACROSS THE AREA...WITH LOWS IN THE LOW 60S. FRI IS EXPECTED TO BE QUITE A PLEASANT SUMMER DAY WITH MOCLR SKIES AND HIGHS IN THE MID 80S...AROUND 80 PLATEAU...WITH DECREASED HUMIDITY VALUES FROM THOSE THAT WE HAVE BEEN EXPERIENCING FOR THE PAST FEW DAYS. AS FOR FRI NIGHT THRU TUE...SOME QUANDARIES STILL ABOUND HERE IN THIS PART OF THE FORECAST PERIOD...BUT NOT AS MUCH AS AROUND THIS TIME YESTERDAY. LATEST DGEX SOLUTION STILL THE ODD MODEL OUT WITH CLOSED LOW NOW PROGGED TO GO ACROSS THE NRN GULF THE FIRST PART OF THE WEEKEND. LATEST GFS MORE IN LINE WITH IMPACTS OF CURRENT TS CHANTAL ACROSS THE SE U.S...WITH NO DIRECT IMPACT TO THE MID STATE ANTICIPATED AT THIS TIME EXPECT FOR POSSIBLY SOME ADDITIONAL MOISTURE BEING ADVECTED ACROSS OUR AREA. THE LATEST GFS/EURO MORE IN LINE WITH EACH OTHER OVERALL IN THE SFC AND UPPER LEVEL PATTERN THAN THIS TIME YESTERDAY AT LEAST THRU THE WEEKEND. THE GFS AND NOW ALSO THE EURO PICKING UP ON THIS ODD RETROGRESSION OF A MID-ATLANTIC CLOSED LOW BACK INTO GA BY NEXT TUE IF YOU BELIEVE THE GFS...AND IF YOU LEAN TOWARD THE EURO...ACTUALLY MOVING ACROSS THE MID STATE DURING THE DAY ON TUE. WHATEVER ACTUAL PATTERN TAKES PLACE...ESPECIALLY WITH CHANTAL MOVEMENT AND POTENTIAL LONGEVITY... IT CONTINUES TO LOOK LIKE THERE WILL BE AT LEAST LOW LEVEL MOISTURE CONTINUANCE ACROSS THE SE U.S. SUN THRU TUE WITH AT LEAST A SLIGHT CHANCE OF SHWRS/TSTMS DURING AT LEAST THE DAYLIGHT HRS DURING THIS TIME PERIOD... AS AN INVERTED UPPER LEVEL TROUGHING PATTERN ACROSS THE NRN GULF STRETCHING NEWD INTO THE MID STATE EVENTUALLY MOVES WWD WITH MORE OF AN UNORGANIZED UPPER LEVEL PATTERN DEPENDENT ON ACTUAL POSITIONS OF UPPER LEVEL STRENGTHENING ALONG WITH SFC RIDGING STRENGTHENING INFLUENCES AND POSSIBLE ABOVE MENTIONED UPPER LEVEL LOW MOVEMENT NEAR OR ACROSS MID STATE... AND WHAT INFLUENCE THAT WILL HAVE ON THE MID STATE'S WX. WITH QUANDARIES STILL ABOUNDING HERE...WILL GENERALLY LEAN CLOSE TO CURRENT FORECAST REASONING WITH TEMPS TRENDING AT OR SLIGHTLY ABOVE SEASONABLE NORMAL VALUES. 31 && .OHX WATCHES/WARNINGS/ADVISORIES...
