AREA FORECAST DISCUSSION

102 PM CDT FRI JUL 16 2010

.UPDATE...
UPDATED TO ADD 18Z AVIATION DISCUSSION

&&

.PREV DISCUSSION... /ISSUED 1104 AM CDT FRI JUL 16 2010/

UPDATE...15Z SURFACE ANALYSIS PLACES A WEAKLY DEFINED COLD FRONT
ACROSS THE MID SOUTH. MEANWHILE...ALOFT AN UPPER LEVEL TROUGH
AXIS IS LOCATED ACROSS THE LOWER MISSISSIPPI VALLEY. A VERY WARM
AND HUMID AIRMASS REMAINS IN PLACE ACROSS THE AREA THIS MORNING
WITH TEMPERATURES AS OF 10 AM CDT IN THE LOWER TO MIDDLE 80S AT
MOST LOCATIONS. SEVERE THUNDERSTORM POTENTIAL FOR THIS
AFTERNOON/EVENING AND HEAT CONCERNS ARE THE MAIN CONCERNS IN THIS
UPDATED DISCUSSION.

LATEST SHORT TERM CONVECTIVE TRENDS SUGGEST SHOWERS AND
THUNDERSTORMS SHOULD INCREASE ACROSS THE MID SOUTH THIS
AFTERNOON...ESPECIALLY ACROSS NORTH MISSISSIPPI AND WEST TENNESSEE
AS THE VERY WARM...MOIST AND CONDITIONALLY UNSTABLE AIRMASS
COMBINE WITH OUTFLOW BOUNDARIES FROM YESTERDAY EVENING/S
CONVECTIVE ACTIVITY AND A WEAK COLD FRONT AND UPPER LEVEL TROUGH
AXIS IN PLACE ACROSS THE REGION.

CONVECTIVE INDICIES FOR THE AFTERNOON YIELD 3000-4000 J/KG SURFACE
BASED CAPE...LI/S -7 TO -8...MODERATELY STEEP 700-500 MB LAYER MID
LEVEL LAPSE RATES AROUND 6.5 C/KM AND PRECIPITABLE WATER VALUES
WELL OVER 2 INCHES...AND RELATIVELY WEAK SHEAR ALOFT 20-30KTS.
THIS SUGGESTS OVERALL CONVECTIVE MODE WILL BE PULSE TYPE
THUNDERSTORMS POTENTIALLY PRODUCING WET MICROBURSTS. THE
CONVECTIVE ACTIVITY IS NOT EXPECTED TO BE ORGANIZED MUCH BUT WITH
SOME WEAK SHEAR PRESENT...SOME CLUSTERING MAY OCCUR WITH THE
ACTIVITY. THUS...THE SEVERE WEATHER THREATS WILL BE DAMAGING WINDS
AND LOCALIZED FLASH FLOODING FROM HEAVY RAINFALL. HAIL IS NOT MUCH
OF A CONCERN AS ATMOSPHERE REMAINS QUITE WARM WITH VERY HIGH
FREEZING LEVELS.

AT THIS TIME NOT MAKING ANY CHANGES TO HEAT ADVISORY HEADLINES AS
TUPELO AND OLIVE BRANCH HAVE ALREADY REACHED HEAT INDICIES OF 105
DEGREES. NONETHELESS...WILL CONTINUE TO MONITOR HEAT TRENDS AS
COVERAGE OF CONVECTIVE ACTIVITY WILL DETERMINE WHETHER EXPANSION
OR CANCELLATION IS NEEDED OVER THE NEXT COUPLE OF HOURS.

WILL MAKE ADJUSTMENTS TO AFTERNOON FORECAST TO RAISE POPS ACROSS
NORTHEAST ARKANSAS TO CHANCE POPS. OTHERWISE...FORECAST OVERALL IS
IN VERY GOOD SHAPE.

UPDATED GRIDS WILL BE PUBLISHED SHORTLY.

DISCUSSION...

UPDATED FOR 12Z AVIATION DISCUSSION.

PREV DISCUSSION... /ISSUED 509 AM CDT FRI JUL 16 2010/

DISCUSSION...

RAIN CHANCES...STRONG TO SEVERE THUNDERSTORM POTENTIAL...AND
DANGEROUS HEAT TODAY ARE THE MAIN CONCERNS.

LATEST MODELS WERE IN FAIR TO GOOD GENERAL AGREEMENT. USED A BLEND
OF THEM WITH NO PREFERENCE FOR ONE MODEL OVER ANOTHER.

THE BIGGEST CHANGE TO THE PREVIOUS FORECAST WAS TO ISSUE A HEAT
ADVISORY TODAY ALONG AND SOUTH OF A WYNNE ARKANSAS TO MEMPHIS TO
SAVANNAH TENNESSEE LINE. ALSO...LOWERED RAIN CHANCES TODAY ACROSS
NORTHEAST ARKANSAS AND THE MISSOURI BOOTHEEL...AND THE ENTIRE AREA
TONIGHT THROUGH MONDAY.

AT 5 AM ACROSS THE MIDSOUTH AND FORECAST AREA...WARM AND MUGGY
CONDITIONS WERE OCCURRING WITH TEMPERATURES IN THE 72 TO 82 DEGREE
RANGE. A FEW DISSIPATING SHOWERS WERE NEAR ALAMO TENNESSEE. AN OLD
OUTFLOW BOUNDARY FROM LAST EVENING/S CONVECTION WAS NEAR A UNION
CITY TO SOMERVILLE TO CLARKSDALE LINE WITH SLIGHTLY HIGHER
DEWPOINTS AND DEEPER LOW LEVEL MOISTURE EAST OF THIS LINE. A WEAK
FRONT WAS JUST NORTHWEST OF THE FORECAST AREA FROM NEAR CAPE
GIRARDEAU MISSOURI TO FORT SMITH ARKANSAS.

ISSUED HEAT ADVISORY TODAY THINKING AREAS SOUTH OF THE LINE
MENTIONED ABOVE WILL HAVE HEAT INDEX VALUES 105 TO 109 DEGREES
BETWEEN 10 AM AND 8 PM WHERE HIGHEST DEWPOINTS ARE EXPECTED.
CONVECTION MAY COOL THINGS OFF BEFORE 8 PM...SO WOULD NOT BE
SURPRISED IF ADVISORY NEEDED TO BE CANCELLED EARLY. ON THE OTHER
HAND...PEAK HEAT INDEX VALUES MAY APPROACH 105 DEGREES NORTH OF
THE ADVISORY AREA...PARTICULARLY OVER NORTHEAST ARKANSAS AND
MISSOURI BOOTHEEL WHERE LESS CONVECTION IS EXPECTED. FOR NOW...
KEPT  THESE AREAS OUT OF THE HEAT ADVISORY AS PERHAPS SOME
SLIGHTLY LOWER DEWPOINTS...IN THE 71 TO 74 DEGREE RANGE AS OPPOSED
TO 73 TO 78 DEGREES EAST OF THE MISSISSIPPI RIVER...MAY KEEP HEAT
INDICES JUST BELOW ADVISORY CRITERIA.

AS FOR RAIN CHANCES TODAY...THINK AREAS NEAR AND EAST OF THE THE
OUTFLOW BOUNDARY MENTIONED ABOVE HAVE THE BEST SHOT FOR SHOWERS
AND THUNDERSTORMS WHERE LOW LEVEL DEWPOINTS ARE HIGHEST AND 700 MB
TEMPERATURES ARE COOLEST...INDICATING WEAKER CAPPING. BELIEVE
FIRST CONVECTION WILL DEVELOP IN THE 10 AM TO 2 PM NEAR THIS
OUTFLOW BOUNDARY...THEN SLOWLY MOVE SOUTHEAST. TIERED RAIN CHANCES
FROM 20 PERCENT OVER NORTHEAST ARKANSAS AND MISSOURI BOOTHEEL TO
50 PERCENT OVER NORTHEAST MISSISSIPPI AND NEAR THE TENNESSEE RIVER.
LOWERED RAIN CHANCES OVER NORTHEAST ARKANSAS AND MISSOURI BOOTHEEL
THINKING SLIGHTLY LOWER DEWPOINTS AND WARMER 700 MB TEMPERATURES
WILL ALLOW FOR BETTER CAPPING COMPARED TO AREAS FARTHER EAST.

REGARDING STRONG TO SEVERE THUNDERSTORM POTENTIAL TODAY...WEAK
SHEAR LESS THAN 20 KTS WILL SUPPORT UNORGANIZED PULSE STORMS. WITH
STEEP LOW LEVEL LAPSE RATES...ABUNDANT MOISTURE IN PLACE WITH
PRECIPITABLE WATER VALUES ABOVE 2 INCHES AND SURFACE DEWPOINTS IN
THE 70S...AND UNSTABLE AIR IN PLACE...A FEW STORMS MAY HAVE GUSTY
WINDS...PERHAPS UP TO SEVERE CRITERIA NEAR 60 MPH...ALONG WITH
VERY HEAVY RAINFALL WHICH COULD PRODUCE A FEW INCHES OF RAINFALL
IN LESS THAN HOUR AND CAUSE LOCALIZED FLASH FLOODING. AREAS EAST
OF A UNION CITY TO MEMPHIS TO CLARKSDALE APPEAR TO HAVE THE BEST
SHOT FOR STRONG/SEVERE STORMS. WIDESPREAD SEVERE AND FLOODING
APPEAR UNLIKELY.

HIGHS EVERYWHERE SHOULD BE IN THE LOWER TO MID 90S...VERY SIMILAR
TO THURSDAY...BUT PERHAPS A DEGREE OR TWO COOLER WITH MORE CLOUDS
AND CONVECTION AROUND.

TONIGHT...WARM AND MUGGY CONDITIONS WILL CONTINUE. KEPT 20 TO 30
PERCENT CHANCE FOR SHOWERS AND STORMS WITH BEST CHANCES NEAR AND
SOUTH OF TUPELO MISSISSIPPI WHERE MOISTURE WILL BE DEEPEST...BUT
MOST...IF NOT ALL...CONVECTION SHOULD DIMINISH BY 10 PM WITH THE
LOSS OF DAYTIME HEATING.

SATURDAY...ANOTHER HOT AND HUMID DAY CAN BE EXPECTED. LOWERED RAIN
CHANCES THINKING INCREASING 700 MB TEMPERATURES +10 TO +12C AND
BEST MOISTURE SHIFTING SOUTH OF THE AREA SHOULD CAP AND INHIBIT
MOST CONVECTION. BEST RAIN CHANCES WILL BE SOUTH OF A CLARKSDALE
TO TUPELO MISSISSIPPI LINE WHERE DEEPEST MOISTURE AND WEAKEST
CAPPING IS FORECAST. CANNOT RULE OUT A FEW STRONG STORMS WITH
GUSTY WINDS...HEAVY RAINFALL...AND LOCALIZED FLOODING. ACCEPTED
00Z MAVMOS TEMPERATURES IN THE LOWER TO MID 90S.

ON SATURDAY...WILL BE CLOSE TO HEAT ADVISORY CRITERIA PARTICULARLY
WEST OF I-55 WHERE HOTTEST TEMPERATURES WILL OCCUR. DID NOT ISSUE
ADVISORY AT THIS TIME AS NOT SURE ABOUT LOW LEVEL DEWPOINTS WHICH
MAY BE JUST LOW ENOUGH TO KEEP HEAT INDEX VALUES BELOW 105
DEGREES.

SATURDAY NIGHT THROUGH SUNDAY NIGHT...HOT...HUMID...AND MAINLY
RAINFREE CONDITIONS CAN BE EXPECTED WITH WEAK RIDGING. WILL BE
CLOSE TO HEAT ADVISORY CRITERIA ON SUNDAY WITH HIGHS IN THE LOWER
TO MID 90S AND DEWPOINTS IN THE 70S.

MONDAY THROUGH THURSDAY...HOT CONDITIONS WILL CONTINUE. WILL BE
CLOSE TO HEAT ADVISORY CRITERIA EACH DAY...ESPECIALLY AROUND
WEDNESDAY WHEN MODELS FORECAST HIGHEST 500 MB HEIGHTS AROUND 597
DM. HIGHS WILL BE WELL INTO THE 90S AND PERHAPS APPROACH 100 BY
THE MIDDLE OF THE WEEK IF THE LOW LEVELS CAN DRY OUT. LATEST
MODELS SUGGESTED A WEAK FRONT MAY APPROACH AREAS NORTH OF I-40 ON
MONDAY...BRINGING PERHAPS A SLIGHTLY HIGHER CHANCE FOR SHOWERS AND
STORMS...BUT THINK MAINLY RAINFREE CONDITIONS WILL OCCUR...SO KEPT
RAIN CHANCES 20 PERCENT OR LESS. GENERALLY WENT A DEGREE OR TWO
WARMER THAN 00Z MEXMOS.

.AVIATION...
18Z TAF CYCLE

SCATTERED SHOWERS AND THUNDERSTORMS HAVE CONTINUED TO DEVELOP OVER
THE PAST COUPLE OF HOURS WITH THE COVERAGE LIMITED MAINLY TO
NORTHEAST MISSISSIPPI THUS FAR. BASED ON LATEST SHORT TERM
CONVECTIVE TRENDS...THINK BEST COVERAGE FOR SHOWERS AND
THUNDERSTORMS WILL BE NEAR TUP AND WILL CARRY A TEMPO GROUP
BETWEEN 18-20Z. AT MEM/MKL/JBR SHOWER AND THUNDERSTORM INITIATION
MAY BE DELAYED BY AT LEAST 2 TO 3 HOURS FROM SUBSIDENCE UPSTREAM
OF THE ONGOING CONVECTION ACROSS NORTHEAST MISSISSIPPI. DUE TO
UNCERTAINTY IN CONVECTIVE COVERAGE AT MEM/MKL/JBR WILL CARRY CB AT
THESE LOCATIONS AND VCTS AFTER 21Z AT MEM/MKL. VFR CONDITIONS WILL
BE PREVALENT AT TAF SITES FOR A MAJORITY OF THE PERIOD. MVFR
VISIBILITIES MAY DEVELOP AT MKL/JBR/TUP AFTER 17/09Z.
