AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
955 AM CDT WED JUL 13 2011

.UPDATE...LATEST SATELLITE IMAGERY SHOWED THE ARKLAMISS UNDER THE INFLUENCE
OF A WEAKEN MEAN RIDGE AXIS EXTENDING FROM THE SOUTHERN PLAINS
THROUGH THE LOWER MISSISSIPPI VALLEY. A SERIES OF DISTURBANCES WILL
WAS MOVING SOUTHEAST OVER THE SOUTHEAST US. ONE OF THEM WAS THE
REMNANT OF AN UPPER LOW...WHICH WILL CROSS THE OZARKS IN 350 PLUS
THETA AIR AND PUSH TOWARD THE ARKLAMISS REGION FOR THIS AFTERNOON.
ALSO GOOD DIVERGENCE WILL AFFECT THE NORTH HALF FOR TODAY. SATELLITE
SHOWS SOME GOOD ASCENT WITH THIS FEATURE WHICH WILL CROSS A SURFACE
BOUNDARY. ALSO OVERNIGHT ACTIVITY OVER THE NORTH HAS
DISSIPATED...BUT HAS LEFT ITS OWN BOUNDARY...WHICH WILL BE USED BY
THE AFTERNOON ACTIVITY. EXPECT ANOTHER COLLISION OF CONVECTIVE
BOUNDARIES ACROSS THE REGION...WHICH WILL HELP TO MOBILIZE MORE
STORMS. SO WITH GOOD INSTABILITY...DECENT LAPSE RATE...AND
PRECIPITABLE WATER OF 2 PLUS INCHES...EXPECT A RATHER ACTIVE DAY.
NATIONAL AND LOCAL WRF ALSO SHOW AN ACTIVE DAY INTO EARLY EVENING.
SPC HAS PUT OUR NORTHERN COUNTIES INTO A SLIGHT RISK AHEAD OF THIS
UPPER FEATURE. SO HAVE INCREASED THE POPS SOME IN OUR NORTHERN
COUNTIES. ALSO WILL KEEP THE HEAT ADVISORY FOR THE NORTH HALF AND
PORTIONS OF THE WEST FOR TODAY AS TEMPS WILL CLIMB INTO THE MID 90S
TO AROUND 100...PUSHING HEAT INDEXES INTO THE 105-110 DEGREE RANGE
WITH 100-105 HEAT INDEXES ELSEWHERE. THE REST OF THE FORECAST LOOKS
TO BE ON TRACK./17/

./PREVIOUS DISCUSSION...446 AM CDT WED JUL 13 2011

.DISCUSSION...SHORT TERM(TODAY THROUGH THURSDAY NIGHT) ANOTHER DAY
OF HEAT AND HUMIDITY ALONG WITH HIGH RAIN CHANCES LOOK TO BE IN
PLACE FOR THE SHORT TERM.

FOR TODAY...ANOTHER WARM DAY IN STORE AS A MUCH WEAKER RIDGE STILL
HOLDS OVER SOME OF THE AREA. HOWEVER...THE CENTER OF THE RIDGE WILL
BE FARTHER TO THE WEST ACROSS CENTRAL TEXAS. A SOUPY AIRMASS WILL
STILL HOLD OVER THE REGION AS PW VALUES ARE STILL PROGGED IN THE
1.9-2.2 INCH RANGE AND 00Z KJAN SOUNDING SHOWS 2.33 INCHES. LOW
LEVEL TEMPERATURES ARE AGAIN FORECAST TO BE IN THE 27-30C RANGE IN
THE NORTH...GENERALLY NORTH OF I-20. THIS WILL ONCE AGAIN BRING
HIGHS TODAY INTO THE UPPER 90S AND NEAR 100 DEGREES. GIVEN THAT SFC
DEWPOINTS WILL AGAIN BE IN THE LOWER TO MID 70S...HEAT INDICES WILL
ONCE AGAIN BE A CONCERN PRIOR TO CONVECTION BEGINNING. WHILE
CONVECTION IS EXPECTED TO BEGIN EARLIER TODAY...THERE SHOULD STILL
BE A FEW HOURS THAT THE HEAT BUILDS AND HEAT INDICES RISE IN THE
105-110 RANGE...PARTICULARLY FOR THOSE IN THE NORTH. GOING HEAT
ADVISORY LOOKS TO HANDLE THIS WELL AND WILL CONTINUE THIS THROUGH
00Z THURSDAY. THE REGION THAT IS MOST QUESTIONABLE AGAIN IS THE EAST
AND SOUTHEAST WHERE PRECIP CHANCES ARE ONCE AGAIN THE BEST. NOT OUT
OF THE QUESTION THERE MAY BE SOME HIGH HEAT INDICES PRIOR TO
CONVECTION...BUT FEEL THAT THIS AREA WILL NOT GET AS WARM DUE TO
BEING WORKED OVER YESTERDAY AND SHOULD SEE MORE TODAY...AS WELL AS
THE DURATION OF HIGHER HEAT INDICES SHOULD NOT BE TOO LONG PRIOR TO
CONVECTION.

ONCE AGAIN...PRECIP CHANCES ARE ON THE HIGHER SIDE(ESPECIALLY FOR
THE SUMMER!) AND EXPECT ANOTHER DAY OF SCATTERED CONVECTION WITH THE
HIGHEST CHANCE OF THIS IN THE SOUTH AND EAST. CHANCES ARE A BIT
HIGHER IN THE NORTH AND NORTHWEST TODAY THAN PREVIOUS DAYS AS THE
RIDGE HAS RETROGRADED. THERE IS A MID LEVEL SHEAR AXIS THAT IS
LAYING GENERALLY ACROSS THE REGION WITH A FEW DISTURBANCES WITHIN
THIS AXIS. THIS SHOULD ONCE AGAIN HELP TO INITIATE CONVECTION WITHIN
A 350-353K THETA-E AIRMASS. HAVE CONTINUED THE TREND OF RAISING POPS
ACROSS THE AREA AS THE GFS CAME IN ON THE LOWER SIDE OF THE ENSEMBLE
ENVELOPE. AS FOR STRONG/SVR POTENTIAL...THIS IS STILL GOING TO BE THE
CASE LIKE PREVIOUS DAYS. WHILE SOME AREAS MAY NOT BE AS HOT TODAY...
CONDITIONS WILL STILL BE WARM AND PLENTY OF LOW LEVEL MOISTURE WILL
BE IN PLACE. GIVEN THIS TEMP/DEWPOINT COMBINATION...SBCAPES WILL BE
SUFFICIENT AND IN THE 2800-3000J/KG RANGE OR HIGHER. WHILE MODEL
VERTICAL TOTALS SHOW AROUND 26-29C...PREVIOUS MORNING SOUNDING
ANALYSIS SHOW THESE VERTICAL TOTALS HAVE BEEN ON THE LOWER END OF
THIS RANGE....AND YET HAVE STILL GENERATED SOME PRETTY DECENT
STRONG/SVR STORMS. FEEL TODAY SHOULD BE NO DIFFERENT. ONCE AGAIN
DAMAGING WINDS WILL BE THE MAIN RISK ALONG WITH DANGEROUS FREQUENT
LIGHTNING AND BRIEF HEAVY DOWNPOURS. MOST CONVECTION WILL DIE DOWN
IN THE EVENING HOURS. HOWEVER...AS AN UPPER TROUGH/300MB LOW MOVES
OVER THE REGION...I CANNOT RULE OUT THE POTENTIAL FOR SOME LINGERING
LIGHT RAIN/SHOWERS TO REMAIN OVER THE AREA. OVERNIGHT LOWS AGAIN WILL
BE WARM AND INTO THE LOWER TO MID 70S.

FOR THURS...THINGS WILL BE SIMILAR. PRECIP CHANCES WILL AGAIN BE
HIGH AND TEMPERATURES WILL REMAIN HIGH AS LL TEMPERATURES STILL
PROGGED TO BE IN THE 27-29C RANGE. HEAT INDICES WILL TOP OUT
GENERALLY IN THE 100-105 RANGE...BUT MAY ALSO EXCEED 105 IN THE
NORTH. COULD SEE A POTENTIAL EXPANSION TO THE HEAT ADVISORY DUE TO
THIS BUT WILL AGAIN LET FUTURE SHIFTS ASSESS THIS GIVEN IMPACTS FROM
CONVECTION TODAY. STRONG TO SVR STORMS WILL AGAIN BE POSSIBLE GIVEN
DECENT LAPSE RATES...SUFFICIENT INSTABILITY. CONTINUED TO INCREASE
POPS AND LEAVE SOME LINGERING OVERNIGHT SHOWERS. /28/

LONGER TERM(FRIDAY THROUGH WEDNESDAY)...UPPER LEVEL VORT DISTURBANCE
DROPS SWD FRIDAY ACROSS OUR CWFA AND IS ASSOCIATED WITH A WEAK MID
LEVEL COLD POOL WITH 500MB TEMPS MINUS 7C. BUILDING 300MB ANTICYCLONE
OVER OK STARTS TURNING THE DISTURBANCE SWWD THROUGH LA BY SATURDAY.
VIRTUALLY NO CHANGE IN DEEP LAYER MOISTURE CONTENT WHICH FEATURES
PWATS OF 2.3 INCHES IS EXPECTED UNTIL SUNDAY NIGHT/MONDAY WHEN DRYING
SPREADS IN FROM THE SRN APPALACHIANS BEHIND A BACKDOOR FRONTAL ZONE.
WE ACTUALLY COULD SEE PWATS DIP TO LESS THAN 1.5 INCHES MONDAY AND
TUESDAY AFTERNOONS KEEPING ANY RISK FOR TSRA IN THE FAR SRN SECTIONS.
BY NEXT WEDNESDAY...INCREASING ELY FLOW IN THE MID AND UPPER LEVELS
BRINGS ADDITIONAL MOISTURE ACROSS THE GULF COAST STATES.

ON FRIDAY/SATURDAY...MODELS DEVELOP MAINLY AFTERNOON SHRA/TSRA AS
RICH 850MB THETA E AIR OF 350K HELPS RESULT IN -4 SHOWALTERS...K
INDEXES NEAR 40 AND MLCAPES AROUND 2500-3000 J/KG. LOOK FOR LOCAL QPF
AMOUNTS OF 1-3 INCHES LIKELY BEFORE SATURDAY EVENING. MAX TEMPS
SHOULD BE HELD MORE IN THE MIDDLE 90S ALONG WITH HEAT INDEXES PEAKING
IN THE 102-106 DEGREE RANGE. A BACKDOOR FRONTAL BOUNDARY SLIPS INTO
THE GULF STATES BY MIDDAY SATURDAY FROM THE NE HELPING MAINTAIN A
FINAL ABOVE NORMAL POP HEADING INTO THE EVENING HOURS. BEST RAIN
CHANCES SHOULD GET DEPRESSED SWD INTO THE HIGHWAY 84 CORRIDOR.

BY SUNDAY...A MASSIVE UPPER ANTICYCLONE REBUILDS OVER MO AND EXPANDS
BACK INTO THE TN VALLEY. IN FACT...IT LOOKS LIKE THE FIRST SUMMER
600DM 500MB HEIGHTS NEAR KMKC FOR SUNDAY DRIFTING INTO CENTRAL KS
MONDAY THEN MOVING LITTLE INTO THE MIDDLE OF NEXT WEEK. MEANWHILE...
OUR 500MB HEIGHTS RISE ABOVE 594DM ONCE SUNDAY WITH TEMPS WARMING TO
MINUS 3-4C. MID LEVEL FLOW INCREASES FROM THE E TO 25KTS BY SUNDAY
AFTERNOON AND BEST UVV S OF I-20 AS SOME DRIER AIR BACKS INTO OUR NRN
CWFA. THIS SURGE WILL START TO SQUASH CONVECTIVE DEVELOPMENT FOR THE
FIRST OF NEXT WEEK AS MID LEVEL LAPSE RATES DROP TO LESS THAN 5C
MON-WED. MLCAPES ALSO DROP TO LESS THAN 800J/KG EACH AFTERNOON AS
THE MAJORITY OF THE CONVECTION BY THAT TIME WILL BECOME CONFINED TO
FAR SRN SECTIONS SUPPORTED BY THE DAILY SEA BREEZE MOVING INLAND./40/

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL FOR MUCH OF THE DAY AS WAS
THE CASE YESTERDAY...HOWEVER BRIEF MVFR TO IFR CONDITIONS DUE TO
STRONG TO SEVERE THUNDERSTORM DEVELOPMENT WILL BE POSSIBLE ACROSS
ALL SITES THIS AFTERNOON AND EARLY EVENING. DAMAGING/TURBULENT WINDS
OF 50-70 MPH AND QUARTER SIZED HAIL WILL BE POSSIBLE WITH STRONGEST
STORMS. WILL CARRY VCTS FOR NOW AND FOR 18Z UPDATE. TAF AMENDMENTS
WILL BE MADE AS CONVECTION FIRES. 1 TO 3 SM RESTRICTIVE VIS WILL
CERTAINLY BE POSSIBLE IF STRONGER DOWNPOURS AFFECT AIRPORT VICINITY.
FREQUENT LIGHTING WILL ALSO BE OF CONCERN THIS AFTERNOON WITH STORM
TOPS REACHING UPWARDS OF 40 TO 45 KFT. NORTHERLY SURFACE WINDS WILL
GENERALLY BE 10 TO 15 KTS FOR LOCATIONS REMOVED FROM THUNDERSTORM
ACTIVITY. EXPECT COVERAGE AND INTENSITY OF ACTIVITY TO DIMINISH BY
10PM WITH WIDESPREAD VFR CONDITIONS RETURNING. SOME PATCHY AREAS OF
FOG WILL OCCUR TOMORROW NEAR DAWN BUT WILL MIX OUT QUICKLY BY 8AM.
