NWS Nashville, TN wrote its last area forecast discussion before the first event at Aug 20, 6:27 PM CST, 1 hour 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NASHVILLE TN 727 PM CDT TUE AUG 20 2013 .UPDATE...FOR 00Z TAFS... && .AVIATION... SCATTERED STORMS ARE STILL MOVING ACROSS THE AREA. ACTIVITY IS EXPECTED TO REMAIN WIDELY SCATTERED THIS EVENING. BEST CHANCE OF A PASSING THUNDERSTORM IS OVER CKV IN THE NEXT COUPLE OF HOURS. MVFR CIGS POSSIBLE AT CSV AND PERIODICALLY AT BNA AND CKV THROUGHOUT THE TAF PERIOD. FOG IS EXPECTED TO DEVELOP IN THE EARLY MORNING HOURS WITH VIS DROPPING DOWN TO IFR CONDITIONS AT TIMES AFTER MIDNIGHT. && .PREV DISCUSSION... /ISSUED 441 PM CDT TUE AUG 20 2013/ MESOSCALE UPDATE... CLUSTER OF CONVECTION WORKING UP THROUGH PUTNAM...JACKSON AND OVERTON COUNTIES AT 0345Z. KDP OFF DUAL POLE SHOWING HEAVIER DOWNPOURS OVER SOUTHEASTERN JACKSON COUNTY AND WESTERN OVERTON. ALSO HEAVY DOWNPOURS NOTED IN SOUTHERN DEKALB. RAINFALL RATES IN LAST HOUR AROUND 1.5 INCHES NEAR COOKEVILLE. THIS ACTIVITY NOW IN SOUTHEAST JACKSON COUNTY. ACTIVITY SHOULD CONTINUE TO WORK NORTHWARD OVER THE NEXT HOUR OR TWO ACCOMPANIED BY LOCALLY HEAVY DOWNPOURS AND FREQUENT CLOUD TO GROUND LIGHTNING STRIKES. BOYD PREV DISCUSSION... /ISSUED 259 PM CDT TUE AUG 20 2013/ DISCUSSION... I LOVE IT WHEN A PLAN COMES TOGETHER. MUCH AS EXPECTED...IN A PATTERN QUITE SIMILAR TO WHAT WE'VE HAD THE LAST TWO OR THREE DAYS...SCATTERED SHOWERS AND A FEW THUNDERSTORMS HAVE POPPED UP AROUND MIDDLE TENNESSEE TODAY. ISOLATED THUNDER WAS MADE POSSIBLE BY MUCH LESS MORNING CLOUD COVER...WHICH ALLOWED FOR MORE LOW-LEVEL INSTABILITY. FORTUNATELY THOUGH...WE ARE STILL UNDER THE WEAK INFLUENCE OF SOME WARMER AIR ALOFT. THEREFORE...ANY FURTHER CONVECTION THIS AFTERNOON WILL LIKELY JUST BE GARDEN VARIETY THUNDERSTORMS...WITH NO SEVERE EXPECTED. BRIEF HEAVY DOWNPOURS ARE ALSO POSSIBLE...SO ROADWAY PONDING AND SOME FLOODING IN POOR DRAINAGE AREAS MAY OCCUR AS WELL. NO SIGNIFICANT ENVIRONMENTAL ALTERATIONS ARE EXPECTED FOR WEDNESDAY. THIS MEANS MUCH LIKE TODAY...WE SHOULD SEE SOME SHOWER ACTIVITY WITH A FEW MORE THUNDERSTORMS MIXED IN. WE WILL NEED TO BE A LITTLE MORE VIGILANT THOUGH...AS THE INFLUENCE OF THE WARM AIR ALOFT MIGHT JUST BE SMALL ENOUGH TO ALLOW A FEW STRONG STORMS DURING THE AFTERNOON. WHILE NO SEVERE WEATHER IS ANTICIPATED...A COUPLE OF STRONG GUSTS AND BRIEF HEAVY DOWNPOURS MAY BE POSSIBLE. THURSDAY STILL LOOKS LIKE A TRANSITION DAY AHEAD OF YET ANOTHER WEAK FRONTAL BOUNDARY ON FRIDAY. A SMALL CHANCE OF CONVECTION WILL BE POSSIBLE THURSDAY...ESPECIALLY FOR OUR NORTHEAST COUNTIES...BUT MOST OF THE ACTIVITY SHOULD BE RELEGATED TO FRIDAY AND FRIDAY EVENING WITH THE FRONT. KEEP IN MIND...THIS IS STILL A SUMMERTIME FRONTAL BOUNDARY PASSAGE. THIS MEANS EXTREMELY DIFFLUENT SURFACE FEATURES...VERY LITTLE ENERGY...AND ALMOST NO WIND SHEAR...SO ANY CONVECTION THAT WANTS TO DEVELOP SHOULD BE VERY DISORGANIZED AND REMAIN BELOW SEVERE CRITERIA. AT MOST...THE FRONT WILL JUST BE A FOCUSING MECHANISM FOR PRECIPITATION TO DEVELOP. EVEN THEN...I'M NOT EXTREMELY IMPRESSED WITH THE QPF AMOUNTS/COVERAGE...SO WILL HOLD ONTO A 30-40 POP THROUGH FRIDAY EVENING. IN ADDITION...I HAVE BACKED OFF A TOUCH ON HIGHS FOR FRIDAY AS GUIDANCE MAY BE A BIT TOO AGGRESSIVE WITH THE RAINS/CLOUD COVER IN PLACE. WHILE THE LATEST GUIDANCE SUGGESTS SOME LOW LEVEL MOISTURE MAY HANG AROUND BEHIND THE FRONTS SATURDAY AND OUR SOUTHERN COUNTIES MAY NEED A SMALL POP...IT LOOKS LIKE FOR THE MOST PART...THE WEEKEND SHOULD BE DRY. THIS IS MAINLY DUE TO THE EASTERN HALF OF THE U.S. COMING UNDER THE INFLUENCE OF A FAIRLY STRONG RIDGE. THE LAST FORECAST PACKAGE WILL BE FOLLOWED PRETTY CLOSELY...WHICH MEANS WE WILL REMAIN OUTSIDE OF THE STRONGEST PORTION OF THE RIDGE. VERY SMALL POPS AND TEMPERATURES IN THE LOW 90S SHOULD RESULT THROUGH THE MIDDLE OF NEXT WEEK. UNGER AVIATION...18Z TAF DISCUSSION. MIDDAY WATER VAPOR SATL IMAGES SHOW SMALL TROF/LOW OVER IL MOVING SLOWLY SOUTHEASTWARD. LIFT AHEAD OF THIS SYSTEM WAS TAPPING INTO THE IMPROVED MOISTURE ACROSS MIDDLE TN...CAUSING SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS AT 18Z. MODELS GRADUALLY PUSH THE DEEPER RH TO THE NORTHEAST THIS AFTERNOON SO BEST CHANCES FOR ADDITIONAL SHOWERS/STORMS SHOULD BE ACROSS THE NORTH AND EAST PARTS OF THE MID STATE. PRECIP SHOULD DIMINISH QUICKLY AROUND SUNSET AS MOISTURE MOVES FURTHER AWAY AND HEATING ENDS. PLENTY OF LOW LEVEL MOISTURE WILL PERSIST OVERNIGHT THROUGH 18Z WEDNESDAY WHILE SFC WINDS REMAIN GENERALLY LIGHT AND VARIABLE. THIS SETS UP LIKELIHOOD OF LOW CLOUDS AND POTENTIAL FOR FOG AT KBNA...KCKV AND KCSV...ESPECIALLY FOR A FEW HOURS AROUND SUNRISE WEDNESDAY. EXPECT MVFR CONDITIONS DURING THOSE HOURS WITH CHANCE OF IFR. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && 11
