AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MEMPHIS TN
1242 PM CDT SUN JUN 28 2009
.UPDATE...
UPDATED FOR AVIATION.
&&
.PREV DISCUSSION... /ISSUED 1118 AM CDT SUN JUN 28 2009/
UPDATE...
NO MAJOR CHANGES PLANNED AT THIS TIME OTHER THAN TO LOWER POPS AREA
WIDE EXCEPT FOR NORTHEAST MISSISSIPPI.
DISCUSSION...
COLD FRONT IS CURRENTLY LOCATED ACROSS THE MIDSOUTH THIS MORNING
AND JUST AHEAD OF THIS FRONT IS A BOUNDARY PUSHING ACROSS NORTH
MISSISSIPPI. BEHIND THIS BOUNDARY...WINDS ARE TURNING NORTHERLY
BUT THE DRIER AIR STILL REMAINS WELL BEHIND THE SURFACE COLD
FRONT. HOWEVER...THIS DRIER AIR IS ALREADY MAKING ITS WAY INTO
NORTHEAST ARKANSAS...THE MISSOURI BOOTHEEL...AND NORTHWEST
TENNESSEE THIS MORNING. WITH ALL THAT SAID...BELIEVE THE GREATEST
CHANCE FOR CONVECTION REMAINS ACROSS NORTHEAST MISSISSIPPI WHERE
THE BEST MOISTURE AND CONVERGENCE RESIDE.
CURRENT HEAT ADVISORY LOOKS FINE AS HEAT INDICES WILL APPROACH
105 DEGREES BUT THIS ADVISORY MAY BE ABLE TO BE CANCELLED FOR SOME
LOCATIONS LATER THIS AFTERNOON AS SOME OF THAT DRIER AIR MOVES
INTO THE MIDSOUTH.
KNS
PREV DISCUSSION... /ISSUED 402 AM CDT SUN JUN 28 2009/
HOT AND HUMID WEATHER WILL CONTINUE ONE LAST DAY ALONG AND SOUTH
OF A WYNNE AR TO SAVANNAH TN LINE BEFORE COOLER AND MUCH DRIER AIR
MOVES INTO THE AREA TONIGHT.
DEALING WITH TODAY/S HEAT FOR AREAS SOUTH OF THE LINE MENTIONED
ABOVE AND STRONG/SEVERE THUNDERSTORM/RAIN POTENTIAL TODAY ARE THE
BIGGEST CONCERNS.
LATEST MODELS WERE IN FAIR TO GOOD AGREEMENT. USED A BLEND OF
THEM. PREFERRED THE 00Z NAM/ECMWF FOR BEST HANDLING TODAY/S
WEATHER. THE 00Z GFS APPEARED TO BE TOO DRY ACROSS THE AREA.
NO MAJOR CHANGES WERE MADE TO THE PREVIOUS FORECAST.
AT 4 AM CDT ACROSS THE MIDSOUTH AND FORECAST AREA...WARM...
MUGGY...AND RAINFREE CONDITIONS WERE OCCURRING WITH SURFACE
TEMPERATURES BETWEEN 70 AND 84 DEGREES. A WEAKENING LINE OF
SHOWERS AND THUNDERSTORMS WERE ALONG A COLD FRONT THAT EXTENDED
FROM NORTHEAST OKLAHOMA TO JUST SOUTH OF ST. LOUIS MISSOURI.
REGARDING THE HEAT ADVISORY TODAY...LEFT ALONE AS IT APPEARS TO BE
IN VERY GOOD SHAPE AS HIGHEST TEMPERATURES...95 TO 99 DEGREES...
AND HIGHEST DEWPOINTS IN THE LOWER 70S...WILL YIELD HEAT INDICES
105 TO 108 DEGREES BETWEEN 11 AM AND 7 PM CDT ALONG AND SOUTH OF A
WYNNE AR TO MEMPHIS TO SAVANNAH TN LINE. DO NOT EXPECT TO EXTEND
ADVISORY IN AREA OR DURATION. MAY BE ABLE TO CANCEL IT A FEW HOURS
EARLY IF THUNDERSTORMS CAN WORK OVER/COOL THE AIR THIS AFTERNOON.
AREAS NORTH OF THE ADVISORY WILL BE COOLER TODAY WITH DECREASING
DEWPOINTS WITH HIGHS MAINLY IN THE LOWER 90S AND HEAT INDEX VALUES
GENERALLY BELOW 100 DEGREES.
REGARDING STRONG/SEVERE/RAIN POTENTIAL TODAY...COLD FRONT WILL
SERVE AS A FOCUS TO PRODUCE LIFT IN A HOT UNSTABLE AIRMASS.
HOWEVER...WEAK LOW LEVEL CONVERGENCE WITH SURFACE WINDS VEERING TO
THE NORTH AND FAIRLY WEAK 0-6 KM SHEAR GENERALLY LESS THAN 25
KTS WILL SUPPORT MAINLY UNORGANIZED PULSE TYPE CONVECTION. BELIEVE
AREAS NEAR THE TN RIVER ALONG THE FAR EASTERN RANGE OF THE
FORECAST AREA WILL HAVE THE BEST SHOT FOR CONVECTION TODAY WHERE
DYNAMICS/LIFT WILL BE BEST AND WHERE CONVECTIVE TEMPERATURES HAVE
THE BEST SHOT OF BEING MET. TIERED RAIN CHANCES 20 PERCENT NEAR
JONESBORO AR TO 50 ALONG THE TN RIVER. DO NOT THINK ALL AREAS
WILL GET WET...BUT AREAS THAT DO GET RAINFALL MAY GET 0.50 INCH
OR MORE. ON AVERAGE...LESS THAN 0.25 INCH OR RAINFALL IS EXPECTED
TODAY ACROSS THE FORECAST AREA.
KEPT A FEW STRONG TO SEVERE STORM MENTION IN HWO AS A FEW WET
MICROBURSTS MAY OCCUR THIS AFTERNOON WITH GUSTY WINDS...SMALL
HAIL...FREQUENT LIGHTNING...AND LOCALLY HEAVY RAINFALL THE
MAIN HAZARDS. DO NOT EXPECT ORGANIZED WIDESPREAD STRONG TO SEVERE
STORMS WITH WEAK DYNAMICS/CONVERGENCE ALONG FRONT.
TONIGHT...A FEW STORMS MAY LINGER SOUTH OF A CLARKSDALE TO FULTON
MS THROUGH 10 PM CDT...BUT OTHERWISE MUCH DRIER AND COOLER AIR
WILL MOVE INTO THE AREA FROM THE NORTH. GUIDANCE LOWS 61 TO 71
APPEARED REASONABLE. SKIES WILL CLEAR AS WELL.
MONDAY...SUNNY AND MUCH MORE COMFORTABLE CONDITIONS WILL OCCUR WITH
SURFACE DEWPOINTS FALLING INTO THE 50S. HIGHS WILL BE NEAR NORMAL
AND MAINLY IN THE LOWER 90S.
MONDAY NIGHT THROUGH THURSDAY NIGHT...DRY AND WARMING CONDITIONS
CAN BE EXPECTED. CHANCES FOR WIDESPREAD RAINFALL APPEAR VERY LOW
DURING THIS TIME FRAME. WEAK FRONTS MAY MOVE THROUGH THE AREA AT
TIMES IN A FAST MID/UPPER LEVEL NORTHWEST FLOW...BUT DEEP MOISTURE
WILL BE LACKING FOR ANY SIGNIFICANT RAINFALL. THE BIG QUESTION
WILL BE TEMPERATURES...WHICH LATEST MODELS SUGGESTED A WARMER
TREND WITH HIGHS IN THE LOWER TO MID 90S. HOWEVER...LOWS SHOULD BE
NEAR OR SLIGHTLY BELOW NORMAL WITH A DRY AIRMASS IN PLACE OVER THE
AREA...MAINLY IN THE MID TO UPPER 60S.
FRIDAY THROUGH INDEPENDENCE DAY...FORECAST CONFIDENCE APPEARS LOW
DURING THIS TIME FRAME...THOUGH LATEST MODELS SUGGEST THAT HIGHER
HUMIDITY AND RAIN CHANCES MAY RETURN TO THE AREA. AT THIS TIME...
KEPT LOW RAIN CHANCES 20 TO 30 PERCENT DURING THIS TIME FRAME.
TEMPERATURES ARE EXPECTED TO BE NEAR OR ABOVE NORMAL.

.AVIATION...
18Z TAFS
FRONTAL BOUNDARY WAS ABOUT 45NM SOUTH OF KTUP AT DISCUSSION TIME.
DRIER POST FRONTAL AIR WAS LAGGING BEHIND THE FRONT...WITH LOWER 70S
DEWPOINTS AND ASSOCIATED INSTABILITY EXTENDING AS FAR NORTH AS KMKL.
THE DRY AIR WAS BEGINNING TO SPREAD INTO KMEM HOWEVER...WITH A 5
DEGREE DEWPOINT DROP MEASURED BETWEEN 16Z AND 17Z.
EVEN THOUGH THE FRONTAL BOUNDARY HAS MOVED SOUTH OF KTUP...
SUFFICIENT INSTABILITY WITH WEAK ELEVATED FORCING WILL LIKELY
RESULT IN A FEW TSRA INTO THE KTUP VICINITY THROUGH 19Z OR 20Z.
KMKL WILL LIKELY SEE LIMITED FORCING WHILE THE DRIER AIR SLOWLY
WORKS IN.
THE REMAINDER OF THE MIDSOUTH...INCLUDING THE KMEM TERMINAL...WILL
SEE VFR CONDITIONS PREVAILING THROUGH THE AFTERNOON...WITH NORTH
WINDS PREVAILING.
