AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
442 PM CDT SUN JUN 9 2013

.DISCUSSION...20Z SURFACE ANALYSIS PLACES A SURFACE LOW OVER
NORTHWEST IOWA WITH A TRAILING COLD FRONT EXTENDING SOUTH ACROSS
WESTERN ARKANSAS THIS AFTERNOON. MEANWHILE ALOFT...WATER VAPOR
SATELLITE/WSR-88D VAD WIND PROFILE TRENDS INDICATE A POSITIVELY TO
PERHAPS NEUTRALLY TILTED UPPER LEVEL TROUGH BEGINNING TO ROTATE
THROUGH THE LOWER MISSISSIPPI VALLEY LATE THIS AFTERNOON. AS A
RESULT...SHOWERS AND THUNDERSTORMS HAVE DEVELOPED OUT AHEAD OF
THIS FRONT...ESPECIALLY ACROSS AREAS ALONG AND WEST OF THE
MISSISSIPPI RIVER. ELSEWHERE...SCATTERED SHOWERS AND THUNDERSTORMS
ARE OCCURRING ACROSS THE REMAINDER OF THE MID SOUTH. TEMPERATURES
AS OF 3 PM CDT ARE PREDOMINANTLY IN THE 80S ACROSS MOST LOCATIONS
WITH TEMPERATURES IN THE 70S WHERE TEMPERATURES ARE COOLER FROM
SHOWERS AND THUNDERSTORMS. SEVERE THUNDERSTORM POTENTIAL THIS
EVENING AND STRONG TO SEVERE THUNDERSTORM POTENTIAL LATE MONDAY
AFTERNOON INTO MONDAY NIGHT ARE THE PREDOMINANT CONCERNS IN THIS
AFTERNOON/S FORECAST ISSUANCE.

.SHORT TERM...(TONIGHT THROUGH WEDNESDAY)...SHORT TERM MODELS ARE
IN AGREEMENT WITH A COLD FRONT MOVING INTO THE MID SOUTH TONIGHT.
LAPS ANALYSIS AS OF 21Z INDICATES AN AREA OF SURFACE BASED CAPE
BETWEEN 2000-3000 J/KG. THIS INSTABILITY COMBINED WITH 0-6 KM BULK
SHEAR VALUES AROUND 40 KTS MAY BE FAVORABLE ENOUGH TO PRODUCE SOME
STRONG TO SEVERE THUNDERSTORMS ACROSS THE MID SOUTH THROUGH EARLY
EVENING. ALTHOUGH 700-500 MB LAYER MID LEVEL HEIGHT FALLS ARE
BELOW 6 C/KM...MODEST 20 TO 40 DM 500 MB MID LEVEL HEIGHT FALLS
MAY BE ABLE TO COMPENSATE FOR THE POOR MID LEVEL LAPSE RATES. A
SEVERE THUNDERSTORM WATCH WAS ISSUED MAINLY ACROSS PORTIONS OF
EAST/NORTHEAST ARKANSAS...THE MISSOURI BOOTHEEL AND MOST OF WEST
TENNESSEE THROUGH 9 PM CDT WHERE THE GREATEST POTENTIAL FOR SEVERE
THUNDERSTORMS MAY OCCUR. NONETHELESS...AN ISOLATED STRONG TO
SEVERE THUNDERSTORM MAY BE POSSIBLE THROUGH EARLY EVENING ACROSS
THE REMAINDER OF THE MID SOUTH.

SHOWERS AND THUNDERSTORMS ARE ANTICIPATED TO DECREASE IN INTENSITY
AND COVERAGE WITH THE LOSS OF DAYTIME HEATING LATER TONIGHT...AND
THE BEST RAIN CHANCES SHIFTING TO ACROSS PORTIONS OF NORTHEAST
MISSISSIPPI AND WEST TENNESSEE NEAR THE TENNESSEE RIVER.

IN ADDITION...MODELS ARE STILL HINTING AT YET ANOTHER POTENTIAL
FOR STRONG TO PERHAPS SEVERE THUNDERSTORMS ACROSS THE MID SOUTH
MAINLY LATE MONDAY AFTERNOON INTO MONDAY NIGHT...ESPECIALLY ACROSS
AREAS NORTH OF I-40 AS THE COLD FRONT BEGINS TO TEMPORARILY
BECOME QUASI-STATIONARY ACROSS THE MID SOUTH AND A SUBTLE MID
LEVEL SHORTWAVE TROUGH ROUNDS THE BASE OF AN UPPER LEVEL THROUGH
AXIS. SURFACE BASED CAPE VALUES BETWEEN 2000-3000 J/KG LATE MONDAY
AFTERNOON COMBINED WITH 0-6 KM BULK SHEAR BETWEEN 40 TO 60
KTS...SOMEWHAT FAVORABLE WINDS ALOFT...MODERATELY STEEPENING
700-500 MB LAYER MID LEVEL LAPSE RATES...AND 0-1 KM STORM RELATIVE
HELICITIES INCREASING TO BETWEEN 200-250 M2/S2...INDICATE A
POTENTIAL FOR STRONG TO SEVERE THUNDERSTORMS DEVELOPING AGAIN
DURING THIS TIMEFRAME. DAMAGING WINDS WILL CONTINUE TO BE THE
PREDOMINANT SEVERE THUNDERSTORM THREAT...ALONG WITH A BETTER
POTENTIAL FOR HAIL TO OCCUR WITH SLIGHTLY COOLER AIR ALOFT AND
UPDRAFTS SUSTAINING THEMSELVES PERHAPS SOMEWHAT LONGER THAN TODAY.
SURFACE/LOW LEVEL MOISTURE WILL REMAIN HIGH AND PRECIPITABLE WATER
VALUES APPROACHING 2 INCHES WILL ALSO SUPPORT A POTENTIAL FOR
LOCALIZED FLASH FLOODING FROM HEAVY RAINFALL. WILL HIGHLIGHT
THREATS IN THE HAZARDOUS WEATHER OUTLOOK.

LATEST MODEL TRENDS SUGGEST A BUILDING RIDGE OVER THE CENTRAL AND
SOUTHERN PLAINS WILL BUILD FURTHER EAST INTO THE LOWER MISSISSIPPI
VALLEY...BRINGING MAINLY RAIN FREE WEATHER BACK TO THE MID SOUTH
FOR TUESDAY INTO WEDNESDAY. TEMPERATURES THROUGH THE SHORT TERM
WILL REMAIN FAIRLY SIMILAR TO TODAY WITH A TREND TOWARD INCREASING
TEMPERATURES INTO TUESDAY/WEDNESDAY AS THE RIDGE BUILDS IN ACROSS
THE AREA. THE MAV GUIDANCE HAS BEEN TRENDING TOO WARM AND LEANED
TOWARDS A BLEND OF THE MET/ECMWF GUIDANCE.

.LONG TERM...(THURSDAY THROUGH SUNDAY)...LATEST 12Z GFS/ECMWF LONG
TERM MODELS INDICATE THE MID SOUTH WILL BE ON THE PERIPHERY OF THE
UPPER LEVEL RIDGE AXIS FROM LATE WEEK INTO NEXT WEEKEND. MODELS
INDICATE THE RIDGE MAY WEAKEN SUFFICIENTLY ENOUGH FOR A BACK DOOR
COLD FRONT TO MOVE INTO PORTIONS OF THE MID SOUTH...ESPECIALLY
EAST OF THE MISSISSIPPI RIVER THURSDAY INTO THURSDAY NIGHT. IN
ADDITION...SOME UNCERTAINTIES STILL REMAIN BEYOND THE REMAINDER OF
THE FORECAST AS THE BACK DOOR COLD FRONT BECOMES QUASI-STATIONARY
AND MEANDERS ACROSS THE AREA THROUGH NEXT WEEKEND. THUS...KEPT
PRECIPITATION CHANCES LOW INITIALLY AND LEFT OUT MENTION OF
SHOWERS AND THUNDERSTORMS OUT OF THE REMAINDER OF THE FORECAST
UNTIL BETTER MODEL CONSENSUS ARRIVES IN SUBSEQUENT FORECASTS. AS
MENTIONED ABOVE THE GFS GUIDANCE HAS BEEN TRENDING WAY TOO WARM
AND LEANED TOWARDS A BLEND OF THE ECMWF AND GFS ENSEMBLE GUIDANCE.

.AVIATION...
18Z TAFS

NOT A LOT OF CHANGE FROM THE PREVIOUS SET OF TAFS. STILL
EXPECTING NUMEROUS SHOWERS AND THUNDERSTORMS THIS AFTERNOON.
STORMS ARE CURRENTLY DEVELOPING ACROSS MUCH OF EAST ARKANSAS...AND
THE AFTERNOON TREND SHOULD BE FOR STORMS TO STRENGTHEN AND
INCREASE IN COVERAGE. THE HEAVIEST ACTIVITY EXPECTED IN THE LATE
AFTERNOON AND EARLY EVENING HOURS. WIND GUSTS OUT OF THUNDERSTORMS
SHOULD PRIMARILY BE FROM THE WEST...BUT COULD COME FROM ANY
DIRECTION.

OUTSIDE OF CONVECTION CIGS WILL BE VFR...WITH IFR/MVFR CONDITIONS
DURING STORMS. WINDS WILL BE SOUTH TO SOUTHWEST AT MAINLY 5-12.

SHOWERS AND THUNDERSTORMS SHOULD GRADUALLY WEAKEN AND DIMINISH IN
COVERAGE AFTER SUNSET WITH MOST PRECIPITATION ENDING BY 06Z. SOME
LOW CLOUDS AND FOG IS EXPECTED TO DEVELOP PRIOR TO SUNRISE NEAR
TUP.
