AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 250 PM EDT WED JUN 11 2003 THE FOLLOWING ARE ALL THE FORECAST DISCUSSIONS FROM THE PAST 24 HOURS...WITH THE MOST RECENT ON TOP. THIS PROVIDES A HISTORY OF THE DEVELOPMENT OF THE CURRENT FORECAST. ********************************************************************* AFTERNOON FORECAST DISCUSSION 250 PM EDT WED JUN 11 2003 TONIGHT AND THURSDAY...CONVECTION FIRING IN BROAD INSTABILITY FIELD OVER EAST TN. SFC THETA E RIDGE STRENGTHENING SINCE THIS MORNING WILL CONTINUE TO DEEPEN AND CONTINUE THROUGH THE EVENING. WEAK SFC RIDGE OVER SRN APPS CAUSING SOME ANTICYCLONIC FLOW INTO TN VALLEY... INCREASING DEWPOINTS AND PRECIPITABLE WATERS. COLD POOL ALOFT AND DEEP MOISTURE HAVE BEEN TWO LEGS OF THE THREE LEGGED TABLE WITH ONLY LOW LEVEL LIFT MISSING. HOWEVER...AS SOME SUN CREEPED IN AND OUTFLOW BOUNDARIES FROM NEARBY COLLAPSING STORMS ENTERS THE AREA...THIS WILL ADD THE THIRD LEG. EXPECT CONVECTION TO CONTINUE INTO THE EVENING. HAVE UPPED POPS TO 50 MOST AREAS WITH 40S ALONG NC BORDER ZONES FOR TONIGHT AS OUTFLOWS CONTINUE. WHILE THREAT OF SEVERE WEATHER WILL LESSEN AS THE SUN DROPS...THREAT OF HEAVY RAINS WILL GROW OVERNIGHT AS DEEP MOISTURE GROWS AND CELLS TRAIN ALONG BOUNDARIES. STILL IN WARM SECTOR OF FRONTAL SYSTEM THURSDAY...BUT WITH COOL FRONT APPROACHING FROM WEST...WILL KEEP HIGH CHANCE (50) POPS IN. EXPECT SOME LEFT OVER BOUNDARIES TOO...BUT SUN WILL BE LIMITED WITH AMOUNT OF CLOUD COVER EXPECTED TO LINGER. DONT EXPECT SEVERE...BUT SOME SHOWERS COULD BE HEAVY AGAIN. TEMPS IN LINE WITH PREVIOUS PACKAGE...EXCEPT HAVE UPPED OVERNIGHT LOWS A LITTLE WITH MORE CLOUDS EXPECTED AND WINDS TO REMAIN UP. THURSDAY NIGHT AND BEYOND...ETA/MESO-ETA MODELS SHOW POTENTIAL WEAKER SHORTWAVE FEATURE AGAIN THURSDAY NIGHT INTO EARLY FRIDAY. GFS MODEL WEAKER WITH THIS FEATURE...BUT GIVEN PLENTY OF MOISTURE AND INSTABILITY...ANY UPPER LEVEL SUPPORT PLUS OROGRAPHICS AND OUTFLOW BOUNDARIES SHOULD EQUAL GOOD COVERAGE OF SHRA/TSRA. DID NOT WANT TO UNDERCUT THE VERY HIGH MOS POPS FOR 3RD AND 4TH PERIODS VERY MUCH...BUT HAD TO COLLABORATE WITH EASTERN CHAT NEIGHBORS AND GO WITH POPS OF 10% TO 20% BELOW MOS BLEND. LITTLE CHANGES MADE FOR NOW BEYOND FRIDAY NIGHT. HAD TO KEEP CHANCE POPS IN PRETTY MUCH RIGHT THROUGH MONDAY. DECISION WAS MADE TO UNDERCUT MRF MOS AND HPC POPS FOR TUE AND WED...BASED ON UPPER RIDGE ACROSS SE STATES AND WEAK UPPER LOW/TROUGH OVER SRN PLAINS. FELT THAT ANY CONVECTION TUE/WED WOULD APPEAR TO BE ISOLATED MAINLY DIURNAL AND LESS THAN 20% COVERAGE. OTHERWISE...SEVERE TSTM WATCH #510 REMAINS IN EFFECT AT FORECAST TIME ...SO ZONES WILL BE GROUPED TO ACCOMODATE WATCH. PRELIMINARY TEMPS AND POPS FOLLOW: FCSTID = 39 CHA 70 84 69 85 / 50 50 60 60 TYS 68 83 67 84 / 40 50 60 50 TRI 65 81 65 82 / 40 50 60 50 OQT 69 83 66 84 / 50 50 60 50 .MRX... NC...NONE. TN...SEVERE THUNDERSTORM (WCN) WATCH FOR THIS AFTERNOON FOR ZONES TNC001...TNC007...TNC009...TNC011...TNC013...TNC025...TNC057... TNC065...TNC067...TNC093...TNC105...TNC107...TNC115...TNC121...

BB/TG ********************************************************************* MID MORNING FORECAST DISCUSSION UPDATE 1040 AM EDT WED JUN 11 2003 CURRENT FORECAST LOOKS WELL ON TRACK. INSTABILITY INCREASING AND ADVECTING IN FROM WEST. LATEST LIS DOWN TO -7 ON SOUTHERN PLATEAU AND DEWPOINT DEPRESSIONS STILL AROUND 3 IN THE SOUTHERN AREAS. ALSO...THETA E RIDGE PROTRUDING INTO SOUTHEAST TN FROM SRN MID TN NOW. ALSO THETA E VALUES INCREASING DRAMATICALLY SRN PLATEAU...10 DEG C IN LAST HOUR. OUCH. WEAK SFC RIDGE OVER AREA HAS ANTICYCLONIC WINDS BUT THIS IS ONLY ADVECTING DEWPOINTS INTO AREA....CURRENTLY MID 70S IN NORTH AL AND SRN MID TEN...DECREASING TO LOW TO MID 60S OVER NE TN/SW VA. WILL NOT UPDATE ZONES THIS MORNING. AFTERNOON ZONE PACKAGE MAY HAVE WORDING OF SOME THUNDERSTORMS MAY BE SEVERE. PRIMARY PROBLEM WILL BE STRAIGHT LINE DAMAGING WINDS. MODEL SOUNDING FORECASTS A LITTLE WEAK ON THE INSTABILITY THIS AFTERNOON, AS WE ARE ALREADY MORE UNSTABLE THAN THE MESO ETA IS FORECASTING. NO MORNING UPDATE...BUT STAY TUNED TO THIS STATION. BB ********************************************************************* EARLY MORNING FORECAST DISCUSSION 400 AM EDT WED JUN 11 2003 LITTLE CHANGE TO FORECAST TREND. UPR TROUGH MOVES NE TONIGHT CLIPPING NW MRX CWA. NW EDGE OF SFC HIGH PRESSURE RIDGING FM ATLC ACROSS FL FLATTENS E TN RVR VLY AS SFC LOW MOVES THROUGH OH RVR VLY. ENTIRE SE U.S. ABOVE NORMAL PWS. EXPECTING WARM NIGHTS THROUGH FCST PERIOD. LOW LVL THICKNESS VALUES RISE WHILE MOS GUIDANCE APPEARS TOO CONSERVATIVE WITH HEAVY WEIGHTING TOWARD CLOUD COVER AND CONVECTION. WILL GO ABOVE GUIDANCE FOR MAXS EXPECTING SOME SUNSHINE. MOS POPS AVG ARND 75% THROUGH SHORT TERM. DONT LIKE TO GO THIS HIGH IN CONVECTIVE SITUATION. BEST GUESS ON TIMING WOULD BE EARLY AND THEN LATE PCPN N AREAS. SOME DEVELOPMENT PLATEAU AND LATER PCPN WITH POSSIBLE OUTFLOW FROM COMPLEXS TO THE NW. TONIGHT SHORT WAVE WILL ENHANCE PCPN ESPECIALLY S AREAS AND CONTINUE CWA WIDE INTO THU. ANOTHER SHORT WAVE FM SW EXPECTED ON FRI. FCSTID = 17 CHA 87 68 83 69 / 30 60 50 50 TYS 87 68 83 69 / 30 40 50 50 TRI 84 65 81 66 / 40 50 50 40 OQT 86 67 83 68 / 30 40 50 50 SON ********************************************************************* EVENING FORECAST DISCUSSION (UPDATE) 930 PM EDT TUE JUN 10 2003 CURRENT AREA RADARS SHOW A MESOSCALE CONVECTIVE SYSTEM RAPIDLY DECAYING OVER THE FORECAST AREA...AS IT ENCOUNTERS A MORE STABLE AIRMASS. SURFACE ANALYSIS SHOWS A COLD FRONT OVER THE MID- MISSISSIPPI VALLEY...WHICH HAS TRIGGERED A STRONG MCS OVER ILLINOIS AND INDIANA. CURRENT THICKNESS PATTERNS INDICATE THAT THIS MCS SHOULD BEGIN TO MOVE SOUTHEAST AS IT APPROACHES NORTHERN KY LATER THIS EVENING. THIS WOULD BRING THE SYSTEM ACROSS SOUTHWEST VA AND POSSIBLY NORTHEAST TN AFTER MIDNIGHT TONIGHT (IF IT HOLDS TOGETHER). LATEST MSAS ANALYSIS REVEALS A STABLE AIRMASS ACROSS SOUTHWEST VA AND NORTHEAST TN...SO THINK THIS SYSTEM SHOULD WEAKEN AS IT MOVES EAST TONIGHT. WITH ALL OF THIS IN MIND...WILL PLAN TO UPDATE THIS EVENING TO REMOVE EVENING PRECIP WORDING...BUT WILL KEEP A CHANCE FOR SHOWERS AND TSTORMS ACROSS SOUTHWEST VA AND NORTHEAST TN AFTER MIDNIGHT. TEMPS LOOK GOOD AND WILL GENERALLY NOT CHANGE. DMG *********************************************************************
