Special Weather Statement, NWS Jackson, MS

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
940 AM CDT THU JUL 30 2015

.UPDATE...
OVERALL FORECAST IS GENERALLY ON TRACK. SFC ANALYSIS INDICATES
FRONTAL BOUNDARY DRAPED ACROSS THE NORTHERN PORTIONS OF THE REGION.
EXPECT ALONG/S OF THE BOUNDARY TO WARM EFFICIENTLY AS COMPRESSIONAL
HEATING AND POOLING OF MOISTURE AID IN TEMPERATURES IN THE MID/UPPER
90S AND HEAT INDICES TO CLIMB ABOVE 105 DEGREES...WITH AREAS IN THE W
MS DELTA AND NE LA TO CLIMB BETWEEN 111-115 DEGREES. EXCESSIVE HEAT
WARNING FOR W MS/NE LA AND HEAT ADVISORY FOR MOST OF THE AREA WILL
CONTINUE UNTIL 7PM TONIGHT. HWO/GRAPHICS LOOK GOOD AND NPW IS SHIPPED
OUT.

ALSO AS THE S/WV ALOFT MOVES IN PER WATER VAPOR IMAGERY AND PW'S IN
REGIONAL 12Z SOUNDINGS ARE IN THE 1.7-2 INCH RANGE...HI-RES GUIDANCE
INCLUDING ARW/NMM AND SSEO INDICATE CONVECTION TO DEVELOP IN THE E/SE
MS. EXPECT MOST ACTIVITY TO DEVELOP MAINLY AFTER 16-17Z AND LASTING
THROUGH 23-01Z. DUE TO SOME INVERTED V SOUNDING...STEEP 850-700MB
LAPSE RATES AROUND 6-7 DEG C/KM...0-3KM LAPSE RATES AROUND 8-9 DEG C
AND VERTICAL TOTALS AROUND 27-29 DEG C...EXPECT MODERATE TO HIGH
INSTABILITY TO DEVELOP ACROSS THE AREA. WITH SOME NRLY FLOW ALOFT
AROUND 15-20KT ESPECIALLY IN E/SE MS...SOME STRONG/SEVERE STORMS
CAPABLE OF STRONG WINDS ARE POSSIBLE. TIMING IN GRAPHICS LOOKS GOOD
OVERALL BUT SOME STORMS COULD POSSIBLY LINGER PAST 6-7PM.

FOR FORECAST ELEMENTS...ADJUSTED CURRENT HOURLY TEMPS/DEWPOINTS TO
BLEND INTO PREVIOUS FORECAST AS IT SEEMS ON TRACK. REST LOOKS GOOD
OVERALL. REST OF THE PRODUCTS ARE SHIPPED OUT. /DC/

&&

.AVIATION...VFR CONDITIONS WILL EXIST WITH THE ONLY RESTRICTIONS
COMING FROM SCT TSRA. A FEW OF THE STRONGER STORMS COULD HAVE SOME
DAMAGING WINDS. WILL FOCUS THE TIMING OF THE VCTS IN THE 18-23Z
RANGE WITH BETTER POTENTIAL TO SEE THIS ACTIVITY ACROSS THE SOUTH
HALF. WINDS WILL BE N/NE TODAY WITH SOME GUSTS APPROACHING 20KTS.
/17/

&&

.PREV DISCUSSION... /ISSUED 407 AM CDT THU JUL 30 2015/

SHORT TERM...FOCUS AGAIN TODAY WILL BE THE OPPRESSIVE HEAT. WHILE
THERE WILL BE SOME STORMS AROUND DURING THE AFTERNOON...FEELING IS
THAT COVERAGE MAY BE LESS THAN PREV EXPECTED WHICH IS SUPPORTED BY
THE LATEST HI-RES TRENDS AS WELL AS THE NAM/GFS. AS FOR THE
HEAT...THE AREA WILL BE LOCATED JUST AHEAD OF A SFC FRONT AND IN THE
LOW LEVEL THERMAL AXIS. WHILE YESTERDAY OFFERED THE MOST OPTIMAL
ZONE TO REALLY HEAT UP...TODAY WILL BE QUITE GOOD...ESPECIALLY
ACROSS THE S HALF. MORE MID/UPPER 90S ARE EXPECTED FOR HIGHS. THE
DIFFERING FACTOR TODAY WILL BE THE REALLY HIGH DEW PTS. THESE WILL
HOLD IN THE MID/UPPER 70S AS MOISTURE POOLS AHEAD OF THE BOUNDARY.
THIS WILL SERVE TO SUPPORT HEAT INDICES BETWEEN 105-110 FOR NEARLY
ALL OF THE AREA WITH SOME LOCATIONS (MAINLY W-CENTRAL) EXCEEDING
110. DUE TO THIS...WILL ADD AN AREA OF THE CWA TO A EXCESSIVE HEAT
WARNING.

AS FOR STORMS...SFC BASED INSTABILITY WILL BE EXTREME TODAY WITH ALL
THE HIGH SFC DEW PTS. HOWEVER...LOWER LEVEL CONVERGENCE SEEMS TO BE
VERY LIMITED DESPITE THE SFC BOUNDARY PUSHING SOUTH.
ADDITIONALLY...THE MID LEVEL S/WV WILL BE SOUTH OF THE CWA AND THE
MID LEVELS WILL BE CHARACTERIZED BY MORE OF A FLAT RIDGE AXIS. THIS
WILL MAKE FOR A MORE HOSTILE CONVECTIVE ENVIRONMENT DESPITE A
CONDUCIVE THERMO ENVIRONMENT. DUE TO THIS...HAVE LOWER POPS FROM THE
PREV FORECAST...BUT THEY STILL REMAIN IN THE 30-40% RANGE FOR A GOOD
PORTION OF THE CWA (S HALF). DESPITE SOME OF THE PRO/CONS...ENOUGH
INGREDIENTS WILL LIKELY EXIST TO SUPPORT A FEW STRONG/SVR STORMS AND
WILL CONTINUE TO MENTION THE LIMITED THREAT FOR TODAY. TIMING WILL
MAINLY BE 2-6PM. LOOK FOR STORM ACTIVITY TO MOVE OFF TO THE SW.

DRIER AIR WILL FILTER INTO THE REGION TONIGHT AND SUPPORT COOLER
TEMPS FOR FRI MORNING AS WELL AS SAT MORNING. NEARLY ALL GUID IS
OFFERING LOWER DEWPTS THAN THE PREV RUNS WHICH WILL SUPPORT MORE OF
AN OPPORTUNITY TO COOL DURING THE OVERNIGHTS. DUE TO THIS...HAVE
LEANED MORE ON THE LATEST MOS OUTPUT WHICH AS MORE OF THE CWA IN THE
UPPER 60S FOR LOW WITH A FEW MID 60 READINGS. HIGHS ON FRI WILL
AGAIN BE WARM...BUT MORE IN THE 92-95 DEGREE RANGE WHICH IS SOME 5
DEGREES LESS THAN WHAT WE HAVE BEEN EXPERIENCING.

MOST OF TONIGHT AND ESPECIALLY FRI-FRI NGT WILL BE PRECIP FREE AS
DEEP LAYER DRY AIR MOVES IN. LOOK FOR VERY ANOMALOUS PWAT AIR WITH
VALUES OF 1.0 IN OR LESS BY FRI AFTERNOON/NIGHT. /CME/

LONG TERM...AT THE BEGINNING OF THE PERIOD...LIGHT MID LEVEL NW FLOW
REGIME WILL BE IN PLACE OVER THE REGION AS RIDGE HAS RETROGRADED AND
BROAD TROFFINESS MOVES THROUGH THE GREAT LAKES REGION. AT THE
SURFACE... MUCH LOWER DEWPOINTS IN THE 50S/60S WILL BE IN PLACE OVER
THE AREA FROM THE AIRMASS CHANGE THAT OCCURRED ON FRIDAY.

THE PATTERN LOOKS TO REMAIN ABOUT THE SAME THROUGH A GOOD CHUNK OF
THE EXTENDED TIMEFRAME. THE DRY AIR WILL CONTINUE TO BE REINFORCED
OVER THE AREA THROUGH TUESDAY AS LIGHT NORTHEASTERLY WINDS BRING DRY
SLUGS OF DRY AIR SOUTHWARD. WITH THE DRIER AIR IN PLACE...HOT
TEMPERATURES WILL BE MORE EASILY ATTAINED...BUT WITH IT BEING MORE OF
A DRY HEAT...HEAT INDICES WILL NOT BE MUCH HIGHER THAN THE AIR TEMP.

A SLIGHT CHANCE OF CONVECTION WILL CONTINUE OVER THE FAR
SE...HOWEVER...IN BETTER LOW LEVEL MOISTURE CLOSER TO THE COAST.
ELSEWHERE DRY WEATHER WILL PREVAIL THROUGH TUESDAY/WEDNESDAY. /26/
