AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
850 PM CDT MON SEP 1 2014

.UPDATE...
TONIGHT WILL BE QUIET AS CONVECTION FROM EARLIER SURGE OF MOISTURE
MOVING TO THE N HAS WINDED DOWN. PWATS HAVE CLIMBED TO ~2.1-2.2
INCHES IN REGIONAL SOUNDINGS/BLENDED SATELLITE TOTALS AND SOME OF
THESE HIGHER CLOUDS COULD LINGER INTO THE EVENING. LEFT ONLY WORDING
OF SOME SHOWERS IN THE FAR SW BUT ENDING BY 02Z. EXPECTING CLOUDS TO
LINGER IN THE AREA BUT SLOWLY DISSIPATE IN THE S/SW AS THE RUC/HRRR
INDICATE SOME MID LEVEL DRYING. AREAS THAT RECEIVED RAINFALL COULD
HAVE SOME PATCHY DENSE FOG...ESPECIALLY IN THE S/SE NEAR
MCB/HBG...BUT NOT EXPECTING IT TO BE WIDESPREAD ENOUGH TO MENTION IN
WX GRIDS DUE TO WIDESPREAD CLOUDINESS. HRRR DOES INDICATES SOME LOW
STRATUS MOVING BACK IN AFTER 06Z TUESDAY AND ADJUSTED SKY GRIDS
ACCORDINGLY. ADJUSTED LOWS SLIGHTLY UPWARD ACROSS THE AREA DUE TO
LINGERING CLOUDS. TWEAKED HOURLY TEMPS/DEWPOINTS TO CURRENT TRENDS.
REST OF THE FORECAST IS ON TRACK. /DC/

&&

.AVIATION...LATE TONIGHT ANTICIPATE WIDESPREAD MVFR TO LOCALLY IFR
CONDITIONS TO DEVELOP BY DAYBREAK TUESDAY. POTENTIAL FOR LOCALLY
DENSE FOG AND/OR IFR FLIGHT CATS IS HIGHEST AT PIB/HBG AREA OF THE
PINE BELT. FLIGHT CATS WILL IMPROVE THROUGH THE MORNING
TOMORROW...AS IS TYPICAL...WITH MORE MORE SCATTERED AFTERNOON
SHOWERS AND STORMS ANTICIPATED LATER TUESDAY. /BB/EC/

&&

.PREV DISCUSSION... /ISSUED 330 PM CDT MON SEP 1 2014/

SHORT TERM...THE MORNING SOUNDINGS SHOWED DRIER AIR ALOFT OVER THE
CWA BUT THE BLENDED TOTAL PRECIPITABLE WATER PRODUCT SHOWS TWO INCH
PWS SURGING BACK NORTH OVER THE SOUTHWEST TWO THIRDS OF OUR CWA.
THIS INCREASE IN DEEP MOISTURE WAS COMBINING WITH TEMPERATURES IN
THE LOW TO MID 90S TO DEVELOP A LITTLE GREATER COVERAGE OF SHOWERS
AND THUNDERSTORMS THIS AFTERNOON. HAVE INCREASED POPS THIS AFTERNOON
ACROSS MUCH OF THE AREA ALTHOUGH ISOLATED COVERAGE IS STILL EXPECTED
IN THE NORTHEAST. CONVECTION WILL DISSIPATE EARLY THIS EVENING.
OVERNIGHT TEMPERATURES WILL AGAIN BOTTOM OUT A LITTLE ABOVE
NORMAL...IN THE MID 70S AT MOST SITES. A WEAK SURFACE RIDGE WILL
NOSE ACROSS THE OUR CWA FROM THE EAST THROUGH WEDNESDAY WHILE A
RATHER FLAT MID LEVEL RIDGE RESIDES OVERHEAD. THIS WILL RESULT IN A
PERSISTENCE FORECAST FOR THE SHORT TERM WITH WARMER THAN NORMAL
TEMPERATURES THROUGH THE PERIOD. BY TUESDAY PWS WILL BE BACK AT OR
ABOVE TWO INCHES AREAWIDE. IN THE ABSENCE OF SIGNIFICANT MORNING
CLOUDINESS...TEMPERATURES WILL WARM UP RAPIDLY. THE WARM
TEMPERATURES WILL COMBINE WITH THE MOIST AIRMASS FOR SCATTERED
COVERAGE OF AFTERNOON AND EVENING STORMS. IT WILL BE HARD TO RULE
OUT A STRONG THUNDERSTORM OR TWO BUT OVERALL...PARAMETERS DO NOT
LOOK THAT FAVORABLE FOR WET MICROBURSTS THE NEXT TWO AFTERNOONS.
/22/

LONG TERM...THURSDAY THROUGH SUNDAY...GFS/ECMWF IN AGREEMENT THIS
PERIOD IN THAT PATTERN OVER THE LOWER CONUS WILL BE DOMINATED BY
FLAT RELATIVELY WEAK DEEP LAYERED RIDGE. AS MID/UPPER RIDGE AXIS
LOOKS TO REMAIN ANCHORED OVER NORTH MS...FLOW OVER THE AREA WILL
REMAIN EASTERLY AND AFFECTED BY ANY WAVES MOVING ALONG THE GULF
COAST. LOW LEVEL FLOW WILL REMAIN SOUTHERLY AS WELL SERVING TO KEEP
MOISTURE PLENTIFUL WITH PW/S REMAINING AROUND 2 INCHES.

HARD TO FIND ANY SIGNIFICANT WAVES IN THE FLOW DURING THIS PERIOD.
WHILE THE LOWER LEVELS LOOK TO BENEFIT MOST FROM THE WARMING FROM
THE RIDGE...MID/UPPER LEVEL TEMPS REMAIN SOMEWHAT COOL (NEAR -10C AT
H5) ALLOWING FOR AFTERNOON VERTICAL TOTALS IN THE MID 20S. BELIEVE
ISOLATED/SCATTERED CONVECTION WILL DOMINATE EACH
AFTERNOON/EVENING...MOST NUMEROUS IN THE SOUTH. SEA BREEZE ACTIVITY
LOOKS TO ENHANCE CONVECTION OVER THE SOUTH...BUT WEAK ONSHORE FLOW
SHOULD LIMIT ITS NORTHWARD EXTENT EACH DAY.

A WEAK FRONTAL BOUNDARY LOOKS TO DIP INTO NORTHERN MS ON SUNDAY
SERVING TO INCREASE CONVECTIVE POTENTIAL OVER THE NORTH BY THAT
TIME./26/

.UPDATE...LATEST SURFACE ANALYSIS HAS A RIDGE NOSING WEST OVER THE
GULF COAST. THE RESULTING LOW LEVEL FLOW AROUND THE RIDGE WAS
HELPING MAINTAIN A RATHER MOIST BOUNDARY LAYER WITH SURFACE DEW
POINTS IN THE MID 70S AT MOST LOCATIONS THIS MORNING BUT DRIER AIR
WAS NOTED ON AREA SOUNDINGS JUST ABOVE THIS LAYER. THE 12Z MON JAN
SOUNDING SHOWED A PW OF 1.63IN WHICH IS QUITE A BIT LOWER THAN THE
PAST SEVERAL DAYS. THIS DRIER AIR IS EXPECTED TO MIX DOWN THIS
AFTERNOON AND LIMIT CONVECTION IN MOST AREAS BUT A SURGE OF DEEP
MOISTURE IS EXPECTED TO MOVE BACK OVER OUR SOUTHERN ZONES AND FUEL
ISOLATED TO SCATTERED STORMS THERE. THE CURRENT FORECAST ACCOUNTS
FOR THIS AND NO SIGNIFICANT CHANGES WERE NEEDED THIS MORNING. /22/

.AVIATION...MVFR FLIGHT CATS STILL BEING OBSERVED THIS MORNING...
MAINLY SOUTH OF I-20 AND ALONG AND WEST OF THE MS RIVER. EXPECT
THESE CONDITIONS TO IMPROVE TO VFR IN THE NEXT ONE TO TWO HOURS.
OTHERWISE...ANTICIPATE SOUTH WINDS UP TO 15 MPH AT TIMES WITH MIDDAY
TO AFTERNOON CU BASED FROM 3 TO 6 KFT. ISOLATED TO SCATTERED MIDDAY
TO AFTERNOON SHOWERS AND STORMS SHOULD MAINLY BE CONFINED SOUTH OF
I-20. FOR LATE TONIGHT EXPECT LOW CLOUDS IN THE MVFR TO LOCALLY IFR
RANGE TO DEVELOP BY DAYBREAK IN ALL AREAS WITH DENSE FOG MOST LIKELY

DISCUSSION...TODAY THROUGH TUESDAY NIGHT...SLIGHTLY ABOVE NORMAL

AREA ON EXPECTED ON TUESDAY.

BEGINNINGS OF LOW STRATUS ARE NOTED ON SATELLITE IMAGERY AS OF 3AM
ALONG HWY 98 CORRIDOR AND EXPECT IT TO EXPAND OVER SOUTH AND CENTRAL
AREAS THROUGH 8-9AM. SOME PATCHY FOG WILL ALSO BE POSSIBLE THROUGH
THAT SAME TIME FRAME BUT NOT EXPECTED TO BE DENSE. LOW CLOUDS/FOG
WILL MIX OUT THROUGH MID MORNING HOURS WITH GOOD AMOUNT OF SUN
EXPECTED BY THIS AFTN. DRIER AIR IN THE H925 TO H7 LAYER AS EVIDENT
WITH 00Z KJAN RAOB OF 1.56" WILL PIVOT NORTH AND ALLOW FOR NEAR 2"
PWATS TO SHIFT INTO SW/S/CENTRAL AREAS FROM THE GULF. THE ADDED
MOISTURE COMBINED WITH EXPECTED SFC BASED INSTABILITY ABOVE 2000
J/KG IN SW/W/CENTRAL AREAS SHOULD PROMOTE ISOLATED TO SCATTERED
SHOWERS/TSTORMS DURING PEAK HEATING THIS AFTN. ACTIVITY SHOULD STAY
TAME AND DISSIPATE THROUGH EARLY EVENING HOURS.

TUESDAY MORNING WILL LIKELY FEATURE ANOTHER ROUND OF LOW STRATUS FOR
SRN AREAS WITH MOIST S/SE LOW-LVL FLOW AS WEAK H85-H5 RIDGING
CONTINUES OVER SE CONUS. THIS RIDGE WILL BECOME FLATTENED INTO
TUESDAY AFTN AS A S/WV TROUGH PIVOTS ACROSS THE GREAT LAKES REGION
AND PUSHES A BOUNDARY SOUTHWARD INTO THE MID SOUTH. THE ARKLAMISS
SHOULD REMAIN SOUTH OF THIS BOUNDARY BUT DAYTIME HEATING COMBINED
WITH SUBTLE WAVES ALONG THE BOUNDARY COULD HELP ENHANCE INSTABILITY
DRIVEN CONVECTION FOR GREATER COVERAGE AND POTENCY. FEEL GREATEST
COVERAGE WILL STILL BE IN SW/W AREAS NEAR MS RIVER DURING THE AFTN
BUT SOME ADDITIONAL ACTIVITY COULD MAKE IT INTO NORTH AREAS LATE
TUESDAY INTO EARLY WEDNESDAY MORNING. /ALLEN/

855 PM CDT SUN AUG 31 2014

.UPDATE...WITH THE LOSS OF DAYTIME HEATING AND INSTABILITY...
COVERAGE OF SHOWERS HAS GREATLY DECREASED ACROSS THE AREA THIS
EVENING...THOUGH THERE ARE JUST A FEW LIGHT SHOWERS HANGING ON
MAINLY ACROSS EAST CENTRAL MS. HEADING INTO THE OVERNIGHT...MOIST
SOUTHERLY FLOW WILL CONTINUE IN THE LOWER LEVELS LIKELY LEADING TO
AN INCREASE IN LOW CLOUDS OVERNIGHT THROUGH EARLY MONDAY MORNING.
THERE MAY ALSO BE PATCHY FOG...PARTICULARLY IN AREAS THAT RECEIVED
RAIN TODAY. WILL UPDATE THE FORECAST TO INCREASE SKY COVER LATER ON
TONIGHT AND MENTION PATCHY FOG. /DL/

&&

.AVIATION...OTHER THAN SOME ISOLATED SHOWER ACTIVITY AND PATCHY CIGS
~3000 FT...VFR CONDITIONS PREVAIL THIS EVENING. WITH CONTINUED
SOUTHERLY LOW LEVEL FLOW...LOW CLOUDS IN THE MVFR TO LOCALLY IFR
RANGE SHOULD REDEVELOP LATE TONIGHT...PARTICULARLY IN SOUTHERN ZONES
WHERE FOG ISSUES TOWARD DAYBREAK MONDAY WILL ALSO BE LIKELY. EXPECT
FOG/STRATUS TO MIX OUT ~15-16Z TOMORROW WITH ISOLATED AFTN SHRA/TSRA
CONFINED SOUTH OF TVR-JAN AND W OF JAN-HBG. /EC/

&&

.DISCUSSION... /ISSUED AT 411 PM CDT SUN AUG 31 2014/
SHORT TERM...THROUGH TUESDAY NIGHT...SURFACE ANALYSIS SHOWED A RIDGE
ORIENTED EAST WEST ALONG THE GULF COAST STATES THAT MODELS PROG WILL
REMAIN IN PLACE THROUGH THE SHORT TERM PERIOD. LOW LEVEL FLOW AROUND
THIS RIDGE WL SERVE TO MAINTAIN SURFACE DEW POINTS IN THE LOW TO MID
70S ACROSS MUCH OF OUR AREA THROUGH THE PERIOD.

LOW CLOUDS WILL LIKELY DELAY HEATING OVER THE SOUTHEAST MONDAY BUT
THERE SHOULD BE A LITTLE MORE SUNSHINE OVER THE CENTRAL AND NORTHERN
PORTIONS ALLOWING FOR WARMER TEMPERATURES. THESE WARM TEMPERATURES
WILL COMBINE WITH OUR VERY MOIST AIRMASS FOR ANOTHER ROUND OF
ISOLATED TO SCATTERED STORMS WITH THE GREATEST COVERAGE AND HIGHEST
POPS OVER THE SOUTHWEST. AGAIN THE ACTIVITY SHOULD DIE DOWN RAPIDLY
AFTER SUNSET.

TUESDAY A SHORTWAVE TROUGH WILL BE SWINGING ACROSS THE NORTH CENTRAL
CONUS AND SUPPORT A WEAK COLD FRONT ACROSS THE MID MISSISSIPPI AND
OHIO RIVER VALLEYS. RIDGING SURFACE AND ALOFT ALONG WITH A MOIST
AIRMASS WILL REMAIN OVER OUR AREA. THE FRONT WILL STALL WELL NORTH
OF OUR CWA BUT THE SHORTWAVE TROUGH MAY EDGE FAR ENOUGH SOUTH INTO
OUR REGION TO HELP ENHANCE CONVECTION DURING THE HEAT OF THE DAY. AS
A RESULT A GREATER COVERAGE OF MAINLY AFTERNOON AND EARLY EVENING
STORMS IS EXPECTED TUESDAY. /22/

LONG TERM...WEDNESDAY THROUGH NEXT WEEKEND...NEAR TO SLIGHTLY ABOVE
NORMAL TEMPERATURES IN THE LOW TO MID 90S EXPECTED WITH ISOLATED TO
SCATTERED AFTERNOON SHOWERS/STORMS THROUGH MUCH OF PERIOD. SUBTLE
FEATURES COULD ACT TO ENHANCE OVERALL RAIN/STORM COVERAGE BY LATE
WEEK.

MAIN FEATURE OF THE PERIOD WILL BE A H7-H5 RIDGE BUILDING IN FROM
THE SUBTROPICAL ATLANTIC EARLY IN THE WEEK BECOMING FLATTENED OVER
THE MID MS VALLEY AND STRETCHED TO THE CAROLINAS BY LATE WEEK.
DESPITE THIS RIDGE, S/WV TROUGHS EMBEDDED IN NRN STREAM FLOW WILL
SKIRT THE MID-SOUTH WHERE A STALLED FRONT WILL LINGER THROUGH MID
WEEK. IN ADDITION TO NRN STREAM INFLUENCE, MODELS SUGGEST A FEW
INVERTED TROUGH FEATURES ALONG THE COAST IN EASTERLY FLOW THAT COULD
HELP ENHANCE SEA-BREEZE ACTIVITY MID TO LATE WEEK. GIVEN PWATS NEAR
2 INCHES AND SURFACE DEWPOINTS IN THE LOW 70S SUPPORTING ADEQUATE
INSTABILITY EACH AFTERNOON, RAIN CHANCES IN THE 20-40% RANGE WILL BE
SUPPORTED BY THIS PATTERN. GREATER RAIN CHANCES WILL BE IN THE
S/SE/E AREAS. MOST SHOWER/STORM ACTIVITY SHOULD DISSIPATE DURING THE
OVERNIGHT EACH DAY. LASTLY, IT MAY NOT BE IMPOSSIBLE FOR A STRONG
PULSE STORM OR TWO DURING THE PEAK HEATING HOURS DURING THE
AFTERNOON HOURS OF THE PERIOD BUT OVERALL RISK WILL BE ASSESSED EACH
DAY. /ALLEN/

WATER PRODUCT SHOWED PWS IN EXCESS OF TWO INCHES WITH THE BAND. THIS
BAND HAS LIMITED HEATING AND INSTABILITY WITH ONLY A FEW ISOLATED
SHOWERS BENEATH IT A MID AFTERNOON. DRIER AIR HAS MIXED INTO THE
SOUTHEAST AND OVER OUR NORTHWEST MOST ZONES ALLOWING FOR GREATER
HEATING AND INSTABILITY AND A LINE OF STORMS HAS DEVELOPED OVER THE
NORTHWEST AND EAST MISSISSIPPI. ADDITIONAL SCATTERED COVERAGE OF
STORMS WILL BE POSSIBLE MAINLY OVER THE SOUTHEAST AND NORTHWEST LATE
THIS AFTERNOON BEFORE CONVECTION DISSIPATES WITH THE LOSS OF DAYTIME
HEATING. SURFACE ANALYSIS SHOWED A RIDGE ORIENTED EAST WEST ALONG
THE GULF COAST STATES THAT MODELS PROG WILL REMAIN IN PLACE THROUGH
THE SHORT TERM PERIOD. LOW LEVEL FLOW AROUND THIS RIDGE WL SERVE TO
MAINTAIN SURFACE DEW POINTS IN THE LOW TO MID 70S ACROSS MUCH OF OUR
AREA THROUGH THE PERIOD. MID TO HIGH CLOUDS MAY INHIBIT FOG
DEVELOPMENT ACROSS THE SOUTHWEST AND WEST TONIGHT BUT THIS IS AN
INDICATION THAT PATCHY DENSE FOG AND/OR LOW STRATUS WILL BE POSSIBLE
MONDAY MORNING OVER THE SOUTHEAST AND EAST CENTRAL PORTIONS OF THE
AREA. THE LOW CLOUDS WILL LIKELY DELAY HEATING OVER THE SOUTHEAST
MONDAY BUT THERE SHOULD BE A LITTLE MORE SUNSHINE OVER THE CENTRAL
AND NORTHERN PORTIONS ALLOWING FOR WARMER TEMPERATURES. THESE WARM
TEMPERATURES WILL COMBINE WITH OUR VERY MOIST AIRMASS FOR ANOTHER
ROUND OF ISOLATED TO SCATTERED STORMS WITH THE GREATEST COVERAGE AND
HIGHEST POPS OVER THE SOUTHWEST. AGAIN THE ACTIVITY SHOULD DIE DOWN
RAPIDLY AFTER SUNSET. TUESDAY A SHORTWAVE TROUGH WILL BE SWINGING
ACROSS THE NORTH CENTRAL CONUS AND SUPPORT A WEAK COLD FRONT ACROSS
THE MID MISSISSIPPI AND OHIO RIVER VALLEYS. RIDGING SURFACE AND
ALOFT ALONG WITH A MOIST AIRMASS WILL REMAIN OVER OUR AREA. THE
FRONT WILL STALL WELL NORTH OF OUR CWA BUT THE SHORTWAVE TROUGH MAY
EDGE FAR ENOUGH SOUTH INTO OUR REGION TO HELP ENHANCE CONVECTION
DURING THE HEAT OF THE DAY. AS A RESULT A GREATER COVERAGE OF MAINLY
AFTERNOON AND EARLY EVENING STORMS IS EXPECTED TUESDAY. /22/

.LONG TERM...WEDNESDAY THROUGH NEXT WEEKEND...NEAR TO SLIGHTLY ABOVE
NORMAL TEMPERATURES IN THE LOW TO MID 90S EXPECTED WITH ISOLATED TO
SCATTERED AFTERNOON SHOWERS/STORMS THROUGH MUCH OF PERIOD. SUBTLE
FEATURES COULD ACT TO ENHANCE OVERALL RAIN/STORM COVERAGE BY LATE
WEEK.

MAIN FEATURE OF THE PERIOD WILL BE A H7-H5 RIDGE BUILDING IN FROM
THE SUBTROPICAL ATLANTIC EARLY IN THE WEEK BECOMING FLATTENED OVER
THE MID MS VALLEY AND STRETCHED TO THE CAROLINAS BY LATE WEEK.
DESPITE THIS RIDGE, S/WV TROUGHS EMBEDDED IN NRN STREAM FLOW WILL
SKIRT THE MID-SOUTH WHERE A STALLED FRONT WILL LINGER THROUGH MID
WEEK. IN ADDITION TO NRN STREAM INFLUENCE, MODELS SUGGEST A FEW
INVERTED TROUGH FEATURES ALONG THE COAST IN EASTERLY FLOW THAT COULD
HELP ENHANCE SEA-BREEZE ACTIVITY MID TO LATE WEEK. GIVEN PWATS NEAR
2 INCHES AND SURFACE DEWPOINTS IN THE LOW 70S SUPPORTING ADEQUATE
INSTABILITY EACH AFTERNOON, RAIN CHANCES IN THE 20-40% RANGE WILL BE
SUPPORTED BY THIS PATTERN. GREATER RAIN CHANCES WILL BE IN THE
S/SE/E AREAS. MOST SHOWER/STORM ACTIVITY SHOULD DISSIPATE DURING THE

AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE JACKSON MS
750 AM CDT SUN AUG 31 2014

.UPDATE...COVERAGE OF GENERALLY LIGHT SHOWERS HAS INCREASED ALONG
AND NORTHWEST OF THE NATCHEZ TRACE CORRIDOR THIS MORNING AS 12Z
SOUNDINGS SUGGESTS LOW LEVEL MOISTURE TRANSPORT ALONG THIS AXIS
REMAINS STRONG. COVERAGE OF SHOWERS WILL BE BEST ACROSS PORTIONS OF
NORTH CENTRAL AND NORTHEASTERN MS WHERE A STRAY RUMBLE OF THUNDER
CANNOT BE RULED OUT. OTHERWISE...ANTICIPATE DRYING AND SOME THERMAL
CAPPING TO LIMIT MIDDAY THROUGH AFTERNOON CONVECTIVE A GOOD DEAL (AT
LEAST IN COMPARISON TO YESTERDAY). /BB/

&&

.PREV DISCUSSION... /ISSUED 341 AM CDT SUN AUG 31 2014/

SHORT TERM...TODAY WILL BE MUCH QUIETER IN THE PRECIP DEPARTMENT AS
SOME DRY ADVECTION MOVES IN FROM THE SE. THIS WILL OCCUR AS OUR
DISTURBANCE (WHICH BROUGHT YESTERDAYS RAINS/STORMS) CONTINUES TO
LIFT NE AND MORE RIDGING DEVELOPS AND THE WESTERN EDGE OF THE
BUILDING FLAT MID LEVEL RIDGE BEGINS TO SHOW ITS INFLUENCE. WHILE
AN OVERALL DRIER AIRMASS (PWS 1.5 TO 1.75 IN) BECOMES SITUATED OVER
PART OF THE CWA...THE NW/N AREAS WILL STILL BE LOCATED IN THE MOIST
AXIS (PWS NEAR 2.0 IN) AND THIS SHOULD BE ENOUGH TO SUPPORT SOME ISO
ACTIVITY TODAY. WHILE MOST OF THIS WILL BE DURING THE AFTERNOON
HOURS...SOME LINGERING MORNING ACTIVITY OVER THE NE/N WILL BE ENOUGH
TO KEEP A MENTION OF PRECIP FOR ALL OF THE DAY PERIOD. LOOK FOR
TEMPS TO BE WARMER THAN YESTERDAY AND MORE LIKE NORMAL CONDITIONS
FOR THE LAST DAY OF AUG (89-93). THE WARMEST READINGS WILL BE OVER
THE SE PORTIONS.

NOT MUCH CHANGE IS EXPECTED FOR MONDAY OTHER THAN SOMEWHAT LESS
PRECIP CHANCES AS MORE OF THE INFLUENCE FROM THE BUILDING RIDGE
OCCURS. STILL...THERE ARE INDICATIONS THAT THIS WILL BE MORE OF A
DIRTY RIDGE AS DECENT MOISTURE WILL WORK ITS WAY INTO THE AREA AND
UNDERNEATH THE RIDGE ALOFT. WHILE STILL ON THE LOW SIDE...THE BEST
PRECIP CHANCES FOR MON WILL BE ACROSS THE S/SW AREAS. AS FOR
TEMPS...READINGS WILL BE WARMER AND HIGHS LOOK TO TOP OUT BETWEEN
93-95. THIS COMBINED WITH HUMIDITY WILL RESULT IN PEAK HEAT INDICES
BETWEEN 100-104. /CME/

LONG TERM...TUESDAY THROUGH NEXT WEEKEND

NEAR TO SLIGHTLY ABOVE NORMAL TEMPERATURES IN THE LOW TO MID 90S
EXPECTED WITH ISOLATED TO SCATTERED AFTERNOON SHOWERS/STORMS THROUGH
MUCH OF PERIOD. SUBTLE FEATURES COULD ACT TO ENHANCE OVERALL
RAIN/STORM COVERAGE BY LATE WEEK.

MAIN FEATURE OF THE PERIOD WILL BE A H7-H5 RIDGE BUILDING IN FROM
THE SUBTROPICAL ATLANTIC EARLY IN THE WEEK BECOMING FLATTENED OVER
THE MID MS VALLEY AND STRETCHED TO THE CAROLINAS BY LATE WEEK.
DESPITE THIS RIDGE, S/WV TROUGHS EMBEDDED IN NRN STREAM FLOW WILL
SKIRT THE MID-SOUTH WHERE A STALLED FRONT WILL LINGER THROUGH MID
WEEK. IN ADDITION TO NRN STREAM INFLUENCE, MODELS SUGGEST A FEW
INVERTED TROUGH FEATURES ALONG THE COAST IN EASTERLY FLOW THAT COULD
HELP ENHANCE SEA-BREEZE ACTIVITY MID TO LATE WEEK. GIVEN PWATS NEAR
2 INCHES AND SURFACE DEWPOINTS IN THE LOW 70S SUPPORTING ADEQUATE
INSTABILITY EACH AFTERNOON, RAIN CHANCES IN THE 20-40% RANGE WILL BE
SUPPORTED BY THIS PATTERN. GREATER RAIN CHANCES WILL BE IN THE
S/SE/E AREAS. MOST SHOWER/STORM ACTIVITY SHOULD DISSIPATE DURING THE
OVERNIGHT EACH DAY BUT THERE COULD BE A WINDOW LATE TUESDAY INTO
EARLY WEDNESDAY SOME SHOWERS COULD LINGER IN NEAR HWY 82 CORRIDOR
DEPENDING HOW FAR SOUTH THE BOUNDARY INFLUENCE OCCURS. LASTLY, IT

OTHER CHANGES TO CURRENT FORECAST. CURRENT SURFACE ANALYSIS SHOWING
WIDESPREAD WARM TROPICAL RAINS SPREADING NORTH ACROSS NE LA/SW MS.
VERY LITTLE LIGHTNING WITH THIS AREA...PW/S NEAR 2.4 INCHES AND WET
BULB ZERO HEIGHTS AROUND 15KFT SUGGEST THAT THESE PROCESSES WILL

AMOUNTS.

SHORT BOWING SEGMENTS IN THE FORECAST REFLECTIVITY...AS WELL
AS...FORECAST WIND GUSTS OF 30-50 KNOTS WITH THE MORE ROBUST
CONVECTION THIS AFTERNOON./26/

.AVIATION...RAIN WILL BE A MORE HIT OR MISS FOR THE EASTERN AREAS
THROUGH TONIGHT. CLOUDS WERE DISSIPATING FOR HBG...GTR AND MEI. AT
THIS TIME...EXPECTING SCT-BKN CLOUDS WITH CEILINGS ABOUT 3000FT.
THUNDERSTORMS MAY DEVELOP AFTER 18Z...SO INTERMITTENT LOW CLOUDS AND
HEAVY RAIN WILL BE POSSIBLE. MAY ADD SOME TEMPO GROUPS FOR RAIN
THROUGH 3Z. GLH WILL LIKELY HAVE RAIN THROUGH THE EVENING...WITH
SOME SHORT BREAKS. EXPECTING RAIN AND/OR FOG TO MAINTAIN MVFR
CONDITIONS THROUGH MUCH OF THE FORECAST PERIOD. THROUGH THE
AFTERNOON AND EVENING LOW CLOUDS AND HEAVY RAIN MAY BRIEFLY LEAD TO
LIFR...MAYBE IFR CONDITIONS. GWO...HKS...JAN WILL SEE MORE
WIDESPREAD RAIN AFTER 18Z. WILL CONTINUE WITH VCTS...ESPECIALLY FOR
JAN/HKS BY LATE AFTERNOON. MVFR/LIFR CONDITIONS WILL BE LIKELY WITH
PERIODS OF HEAVY RAIN AND LOW CLOUDS. WILL ADD PATCHY FOG AND
STRATUS TO ALL SITES FROM 9-12Z. /7/


&&

.PREV DISCUSSION... /ISSUED 336 AM CDT SAT AUG 30 2014/

SHORT TERM...ACTIVE WEATHER DAY ON TAP AS HIGHLY MOIST AIRMASS WILL
FUEL SHRA/TSRA TODAY AS A DISTURBANCE LIFTS NORTHWARD OUT OF THE
NORTHER GULF AND S-CENTRAL SECTIONS OF LA. RECENT DAYS WE HAVE BEEN
ADVERTISING THE POTENTIAL FOR LOCALLY HEAVY RAINFALL AND SOME
POTENTIAL FOR FLASH FLOODING. THIS RISK STILL EXISTS AS EFFICIENT
RAINS WILL BE POSSIBLE AS FORCING FOR ASCENT WILL MAKE THE MOST OF
THE 2.2-2.4 IN PW AIRMASS. HOWEVER...AN ADDITIONAL THREAT FOR GUSTY
AND POSSIBLY DAMAGING WINDS EXISTS AS WELL. THE REASON FOR THIS NEW
THREAT RESIDES IN THE INCREASED FLOW BETWEEN THE 2-12 KFT LAYER.
NEARLY ALL GUIDANCE INDICATES THIS LAYER WILL CONTAIN 30-40 KTS OF
FLOW. WHILE HEATING TODAY WILL BE LIMITED AND THE THERMODYNAMIC
PROFILE WILL BE QUITE TAME...MID/UPPER 80S DEGREE TEMPS WILL SUPPORT
SBCAPE NEAR 2000 J/KG AND THIS WILL BE MORE THAN ENOUGH ENERGY TO
SUPPORT DEEP CONVECTION (ESP WITH THE DISTURBANCE PROVIDING STRONG
FORCING). FURTHERMORE...ORGANIZING CONVECTION WILL BE ABLE TO
UTILIZE THE INCREASED FLOW TO ORGANIZE COLD POOLS. IF ANY COLD POOL
ORGANIZES IN A FASHION WHERE IT MOVES IN TANDEM WITH THE FLOW BELOW
12KFT (WHICH LOOKS TO BE IN A NNE DIRECTION) BOWING SEGMENTS WILL BE
POSSIBLE AND LIKELY EFFICIENTLY BRING DOWN THE STRONGER WINDS ALOFT. IN
TURN...THIS WILL INCREASE THE WIND DAMAGE POTENTIAL. IT IS ALSO WORTH
NOTING THAT THE INCREASED FLOW WILL ALSO INCREASE THE LOW LEVEL
HELICITY TO VALUES THAT COULD SUPPORT A BRIEF TORNADO. WHILE THIS IS
NOT A PRIMARY THREAT...IT CAN`T BE RULED OUT. DUE TO ADDED
RISKS...WILL INTRODUCE A LIMITED SVR RISK FOR DAMAGING WINDS. AS FOR
A LOCATION...MOST OF THE AREA WILL HAVE A RISK...THE EXCEPTIONS LOOK
TO THE BE THE FAR SW AND THE I-59 CORRIDOR. BEST TIMING WOULD BE FROM
11AM TO 5PM. THE HWO/GRAPHICS WILL HIGHLIGHT THE TIMING AND THREAT
AREA.

AS FOR OTHER FORECAST ELEMENTS (POPS AND WEATHER)...GUIDANCE POPS
WERE HIGHER FROM THE PREV RUNS AND I FOLLOWED THOSE HIGH VALUES AND
INCREASED SOME LOCATIONS TO STAY IN LINE WITH PREV FORECASTS. THE
MAIN TIMING FOR THIS ACTIVITY WAS ADJUSTED...THE SW LOOKS TO BE THE
AREA THAT GETS IT FIRST AND EARLIEST WITH THE REMAINDER OF THE AREA
SOMETIME BETWEEN LATE MORNING AND LATE AFTERNOON. FOR THIS
EVE/OVERNIGHT...MUCH MORE OF TRICKY FORECAST EXISTS FOR TONIGHT. IT
SEEMS LIKE THERE WILL BE A LULL PERIOD FROM LATE AFTERNOON INTO MOST
OF THE EVE...THEN ACTIVITY COULD PICK UP AFTER MIDNIGHT OVER THE NW/N
AREAS. THE S HALF LOOKS TO SEE LESS ACTIVITY THAN PREV EXPECTED AS
DRIER AIR MOVES NORTHWARD IN THE WAKE OF THE MAIN S/WV.

SUNDAY LOOKS TO BE LESS ACTIVE AS WELL THANKS TO THE DRIER AIR
MOVING UP FROM THE S/SE AROUND THE EVOLVING RIDGE. STILL...ENOUGH
MOISTURE WILL EXIST FOR SOME ISO/SCT ACTIVITY. THE GFS WAS REALLY LOW
WITH POPS AND I USED A BLEND OF THE GFS/EURO FOR THE POP FORECAST.
WITH LESS PRECIP AROUND...LOOK FOR WARMER TEMPS (90-95). /CME/

LONG TERM...MONDAY THROUGH NEXT SATURDAY

NEAR TO SLIGHTLY ABOVE NORMAL TEMPERATURES IN THE LOW TO MID 90S AND
TYPICAL 20-30% AFTERNOON CHANCES OF SHOWERS/STORMS THROUGH MOST OF
THE WEEK AS A HIGH PRESSURE RIDGE BUILDS OVER THE SE/CENTRAL CONUS.

THE CURRENT SYSTEM RESPONSIBLE FOR ELEVATED RAIN CHANCES THIS
WEEKEND WILL PULL OFF TO THE NE BY LABOR DAY AND A SUBTROPICAL H7-H5
RIDGE LOOKS TO BUILD IN FROM THE ATLANTIC WHILE THE NRN STREAM FLOW
BECOMES MOSTLY ZONAL. DESPITE LOW-LVL HIGH PRESSURE AXIS AND SLOWLY
BUILDING HEIGHT INFLUENCE OVER REGION MOST OF THE WEEK, PWATS WILL
REMAIN ELEVATED /NEAR 2"/ AND COMBINED WITH DAILY AFTERNOON
INSTABILITY /2000 J/KG+/, ISOLATED/SCATTERED SHOWERS/STORMS WILL BE
LIKELY. OVERALL COVERAGE WONT BE GREAT BUT FEEL BEST COVERAGE WILL
BE IN S/SE/E WHERE SEA-BREEZE CONVERGENCE AND HIGHEST PWATS WILL
EXIST. HEAT INDICES MONDAY AND TUESDAY SHOULD REACH INTO THE LOW
100S FOR A FEW HOURS WITH LOWS ONLY FALLING INTO THE LOW TO MID 70S
THROUGH MUCH OF THE WEEK.

ON TUESDAY, A SLIGHTLY STRONGER S/WV TROUGH ACROSS THE CORN BELT
WILL ATTEMPT TO BRING A BOUNDARY SOUTH TOWARDS THE REGION BUT FEEL
IT STAY NORTH AND THUS KEPT POPS/SHOWERS OUT OF FORECAST FOR
NORTHERN AREAS. FOR WEDNESDAY THROUGH FRIDAY, RIDGING WILL REMAIN
OVER AREA AND STRENGTHEN SLIGHTLY BUT SEA-BREEZE INITIATED AND
DIURNAL ACTIVITY SHOULD CONTINUE TO BE A GOOD POSSIBILITY EACH DAY.
BY SATURDAY, THE RIDGING SLIPS FARTHER WEST AND PLACES REGION IN
SLIGHTLY GREATER N/NE FLOW THAT COULD ENHANCE SHOWER COVERAGE
POSSIBILITIES.  /ALLEN/

.AVIATION...RAIN WILL BE A MORE HIT OR MISS FOR THE EASTERN AREAS
THROUGH TONIGHT. CLOUDS WERE DISSIPATING FOR HBG...GTR AND MEI. AT
THIS TIME...EXPECTING SCT-BKN CLOUDS WITH CEILINGS ABOUT 3000FT.
THUNDERSTORMS MAY DEVELOP AFTER 18Z...SO INTERMITTENT LOW CLOUDS AND
HEAVY RAIN WILL BE POSSIBLE. MAY ADD SOME TEMPO GROUPS FOR RAIN
THROUGH 3Z. GLH WILL LIKELY HAVE RAIN THROUGH THE EVENING...WITH
SOME SHORT BREAKS. EXPECTING RAIN AND/OR FOG TO MAINTAIN MVFR
CONDITIONS THROUGH MUCH OF THE FORECAST PERIOD. THROUGH THE
AFTERNOON AND EVENING LOW CLOUDS AND HEAVY RAIN MAY BRIEFLY LEAD TO
LIFR...MAYBE IFR CONDITIONS. GWO...HKS...JAN WILL SEE MORE
WIDESPREAD RAIN AFTER 18Z. WILL CONTINUE WITH VCTS...ESPECIALLY FOR
JAN/HKS BY LATE AFTERNOON. MVFR/LIFR CONDITIONS WILL BE LIKELY WITH
PERIODS OF HEAVY RAIN AND LOW CLOUDS. WILL ADD PATCHY FOG AND
STRATUS TO ALL SITES FROM 9-12Z. /7/

.PREV DISCUSSION... /ISSUED 336 AM CDT SAT AUG 30 2014/

SHORT TERM...ACTIVE WEATHER DAY ON TAP AS HIGHLY MOIST AIRMASS WILL
FUEL SHRA/TSRA TODAY AS A DISTURBANCE LIFTS NORTHWARD OUT OF THE
NORTHER GULF AND S-CENTRAL SECTIONS OF LA. RECENT DAYS WE HAVE BEEN
ADVERTISING THE POTENTIAL FOR LOCALLY HEAVY RAINFALL AND SOME
POTENTIAL FOR FLASH FLOODING. THIS RISK STILL EXISTS AS EFFICIENT
RAINS WILL BE POSSIBLE AS FORCING FOR ASCENT WILL MAKE THE MOST OF
THE 2.2-2.4 IN PW AIRMASS. HOWEVER...AN ADDITIONAL THREAT FOR GUSTY
AND POSSIBLY DAMAGING WINDS EXISTS AS WELL. THE REASON FOR THIS NEW
THREAT RESIDES IN THE INCREASED FLOW BETWEEN THE 2-12 KFT LAYER.
NEARLY ALL GUIDANCE INDICATES THIS LAYER WILL CONTAIN 30-40 KTS OF
FLOW. WHILE HEATING TODAY WILL BE LIMITED AND THE THERMODYNAMIC
PROFILE WILL BE QUITE TAME...MID/UPPER 80S DEGREE TEMPS WILL SUPPORT
SBCAPE NEAR 2000 J/KG AND THIS WILL BE MORE THAN ENOUGH ENERGY TO
SUPPORT DEEP CONVECTION (ESP WITH THE DISTURBANCE PROVIDING STRONG
FORCING). FURTHERMORE...ORGANIZING CONVECTION WILL BE ABLE TO
UTILIZE THE INCREASED FLOW TO ORGANIZE COLD POOLS. IF ANY COLD POOL
ORGANIZES IN A FASHION WHERE IT MOVES IN TANDEM WITH THE FLOW BELOW
12KFT (WHICH LOOKS TO BE IN A NNE DIRECTION) BOWING SEGMENTS WILL BE
POSSIBLE AND LIKELY EFFICIENTLY BRING DOWN THE STRONGER WINDS ALOFT. IN
TURN...THIS WILL INCREASE THE WIND DAMAGE POTENTIAL. IT IS ALSO WORTH
NOTING THAT THE INCREASED FLOW WILL ALSO INCREASE THE LOW LEVEL
HELICITY TO VALUES THAT COULD SUPPORT A BRIEF TORNADO. WHILE THIS IS
NOT A PRIMARY THREAT...IT CAN`T BE RULED OUT. DUE TO ADDED
RISKS...WILL INTRODUCE A LIMITED SVR RISK FOR DAMAGING WINDS. AS FOR
A LOCATION...MOST OF THE AREA WILL HAVE A RISK...THE EXCEPTIONS LOOK
TO THE BE THE FAR SW AND THE I-59 CORRIDOR. BEST TIMING WOULD BE FROM
11AM TO 5PM. THE HWO/GRAPHICS WILL HIGHLIGHT THE TIMING AND THREAT
AREA.

AS FOR OTHER FORECAST ELEMENTS (POPS AND WEATHER)...GUIDANCE POPS
WERE HIGHER FROM THE PREV RUNS AND I FOLLOWED THOSE HIGH VALUES AND
INCREASED SOME LOCATIONS TO STAY IN LINE WITH PREV FORECASTS. THE
MAIN TIMING FOR THIS ACTIVITY WAS ADJUSTED...THE SW LOOKS TO BE THE
AREA THAT GETS IT FIRST AND EARLIEST WITH THE REMAINDER OF THE AREA
SOMETIME BETWEEN LATE MORNING AND LATE AFTERNOON. FOR THIS
EVE/OVERNIGHT...MUCH MORE OF TRICKY FORECAST EXISTS FOR TONIGHT. IT
SEEMS LIKE THERE WILL BE A LULL PERIOD FROM LATE AFTERNOON INTO MOST
OF THE EVE...THEN ACTIVITY COULD PICK UP AFTER MIDNIGHT OVER THE NW/N
AREAS. THE S HALF LOOKS TO SEE LESS ACTIVITY THAN PREV EXPECTED AS
DRIER AIR MOVES NORTHWARD IN THE WAKE OF THE MAIN S/WV.

SUNDAY LOOKS TO BE LESS ACTIVE AS WELL THANKS TO THE DRIER AIR
MOVING UP FROM THE S/SE AROUND THE EVOLVING RIDGE. STILL...ENOUGH
MOISTURE WILL EXIST FOR SOME ISO/SCT ACTIVITY. THE GFS WAS REALLY LOW
WITH POPS AND I USED A BLEND OF THE GFS/EURO FOR THE POP FORECAST.
WITH LESS PRECIP AROUND...LOOK FOR WARMER TEMPS (90-95). /CME/

LONG TERM...MONDAY THROUGH NEXT SATURDAY

NEAR TO SLIGHTLY ABOVE NORMAL TEMPERATURES IN THE LOW TO MID 90S AND
TYPICAL 20-30% AFTERNOON CHANCES OF SHOWERS/STORMS THROUGH MOST OF
THE WEEK AS A HIGH PRESSURE RIDGE BUILDS OVER THE SE/CENTRAL CONUS.

THE CURRENT SYSTEM RESPONSIBLE FOR ELEVATED RAIN CHANCES THIS
WEEKEND WILL PULL OFF TO THE NE BY LABOR DAY AND A SUBTROPICAL H7-H5
RIDGE LOOKS TO BUILD IN FROM THE ATLANTIC WHILE THE NRN STREAM FLOW
BECOMES MOSTLY ZONAL. DESPITE LOW-LVL HIGH PRESSURE AXIS AND SLOWLY
BUILDING HEIGHT INFLUENCE OVER REGION MOST OF THE WEEK, PWATS WILL
REMAIN ELEVATED /NEAR 2"/ AND COMBINED WITH DAILY AFTERNOON
INSTABILITY /2000 J/KG+/, ISOLATED/SCATTERED SHOWERS/STORMS WILL BE
LIKELY. OVERALL COVERAGE WONT BE GREAT BUT FEEL BEST COVERAGE WILL
BE IN S/SE/E WHERE SEA-BREEZE CONVERGENCE AND HIGHEST PWATS WILL
EXIST. HEAT INDICES MONDAY AND TUESDAY SHOULD REACH INTO THE LOW
100S FOR A FEW HOURS WITH LOWS ONLY FALLING INTO THE LOW TO MID 70S
THROUGH MUCH OF THE WEEK.

ON TUESDAY, A SLIGHTLY STRONGER S/WV TROUGH ACROSS THE CORN BELT
WILL ATTEMPT TO BRING A BOUNDARY SOUTH TOWARDS THE REGION BUT FEEL
IT STAY NORTH AND THUS KEPT POPS/SHOWERS OUT OF FORECAST FOR
NORTHERN AREAS. FOR WEDNESDAY THROUGH FRIDAY, RIDGING WILL REMAIN
OVER AREA AND STRENGTHEN SLIGHTLY BUT SEA-BREEZE INITIATED AND
DIURNAL ACTIVITY SHOULD CONTINUE TO BE A GOOD POSSIBILITY EACH DAY.
BY SATURDAY, THE RIDGING SLIPS FARTHER WEST AND PLACES REGION IN
SLIGHTLY GREATER N/NE FLOW THAT COULD ENHANCE SHOWER COVERAGE
POSSIBILITIES.  /ALLEN/

.AVIATION...LOOK FOR CEILINGS TO TREND DOWNWARD TO MVFR WITH A SITE

NORTHWARD WHICH WILL SERVE TO KEEP CEILINGS IN THE MVFR CATEGORY

14-21Z FOR THE TAF SITES AND I WILL FOCUS THE WORST CONDITIONS THEN.
THERE WILL ALSO BE THE RISK FOR GUSTY WINDS WITH SOME STRONGER
