AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE JACKSON MS
500PM CDT TUE AUG 23 2005

.DISCUSSION...NUMEROUS SHOWERS AND THUNDERSTORMS HAVE
DEVELOPED AND ARE CONTINUING OVER NORTHERN LOUISIANA...NORTHERN
MISSISSIPPI...AND MUCH OF ARKANSAS. THIS HAS ALLOWED MANY AREAS
ACROSS CENTRAL MISSISSIPPI...AND NORTHEASTERN LOUISIANA TO AGAIN GET
INTO THE UPPER 90S. WITH THE TEMPS THIS WARM AND DEWPOINTS IN THE
LOWER 70S THE ATMOSPHERE HAS BECOME VERY UNSTABLE AND UNTAPPED.

THIS EVENING AS OUTFLOW BOUNDARIES FROM EARLIER THUNDERSTORMS MOVE
ACROSS THIS UNTAPPED REGION LOOK FOR ADDITIONAL THUNDERSTORM
DEVELOPMENT LIKELY LASTING INTO THE LATTER EVENING HOURS. WITH THE
AMOUNT OF INSTABILITY IN THE AIR...A FEW OF THESE THUNDERSTORMS MAY
BECOME STRONG AND POSSIBLY SEVERE WITH STRONG WINDS THE MAIN THREAT.
ANOTHER THREAT FROM THESE STORMS WILL BE MODERATE TO HEAVY RAINFALL
AND FREQUENT TO ALMOST CONSTANT LIGHTNING.

AS THE 9 PM APPROACHES SHOWERS AND THUNDERSTORMS SHOULD START TO DIE
DOWN...ESPECIALLY WITH THE LOSS OF DAYTIME HEATING. THAT SAID OVERALL
ACTIVITY WILL STILL LIKELY LAST PAST 9 PM.

ACROSS SOUTHEASTERN MISSISSIPPI...SHOWERS AND THUNDERSTORMS WILL
HAVE A HARDER TIME DEVELOPING MAINLY DUE TO THE LACK OF LOW LEVEL
MOISTURE. THERE MAY BE A FEW STORMS ACROSS THAT AREA LATE TONIGHT AS
STORMS ACROSS CENTRAL MISSISSIPPI PUSH SOUTH. /24/

&&

.PREV DISCUSSION...EXPECT MOST OF THE CONVECTION TO DISSIPATE THIS
EVENING BY SUNSET BUT THERE SHOULD STILL BE SOME LINGERING ACTIVITY
IN THE NORTHERN AREAS ALONG THE FRONTAL BOUNDARY. BY TOMORROW THE
FRONTAL BOUNDARY WILL STILL BE LOCATED OVER NORTH CENTRAL
MISSISSIPPI AND WILL CONTINUE TO SLOWLY DRIFT SOUTH DURING THE DAY.
THE GFS IS ALSO INDICATING THAT A SHORT WAVE WILL MOVE ACROSS
NORTHERN MISSISSIPPI TOMORROW AFTERNOON. PRECIPITABLE WATER VALUES
ACROSS THE AREA WILL STILL BE NEAR 2.2 INCHES...ML CAPES WILL BE
BETWEEN 2000 TO 2400. WITH THESE FACTORS EXPECT AFTERNOON AND
EVENING CONVECTION TO ONCE AGAIN FORM WITH THE HIGHEST POPS IN THE
SOUTH WITH THE SEA BREEZE. FEEL THERE WILL NOT BE ENOUGH INSTABILITY
FOR SEVERE BUT A STRONG STORM CANNOT BE RULED OUT. WILL GO AHEAD AND
ISSUE ANOTHER HEAT ADVISORY FOR TOMORROW FOR THE WESTERN AREAS
...TEMPS IN THE MID 90S AND DEW POINTS REMAINING IN THE LOW 70S
COMBINE FOR HEAT INDICES IN THE 105 TO 110 RANGE./#15/

THURSDAY THROUGH TUESDAY...MODELS ARE CONTINUING TO BE CONSISTENT
WITH THE SEASONAL UPPER PATTERN THROUGH THE LONG TERM PERIOD.
HOWEVER THE UK...EUROPEAN...NOGAPS AND THE CANADIAN MODELS WERE
SHOWING SOME TYPE OF TROPICAL SYSTEM PUSHING INTO THE GULF OF MEXICO
AREA FOR THE LATER PART OF THIS WEEKEND INTO EARLY NEXT WEEK...WHILE
THE GFS TAKES IT UP THE EAST COAST. MANUAL PROGS TAKES THE SYSTEM TO
THE CENTRAL GULF THIS WEEKEND INTO EARLY NEXT WEEK. SO EACH MODEL
HAD SOME DIFFERING SOLUTIONS ON THE PATH OF THE SYSTEM. SO HAVE
LITTLE CONFIDENCE ON THE AFFECTS OF THIS SYSTEM AT THIS TIME.
OTHERWISE BROAD UPPER RIDGE WILL CONTINUE OVER THE REGION. THERE
WILL BE ENOUGH INSTABILITY FOR DIURNAL CONVECTION THROUGH THE
PERIOD. THE WEAK SURFACE BOUNDARY WILL PUSH TO THE SOUTH ON
THURSDAY. PRECIPITABLE WATER WILL RANGE FROM 1.7 TO 2.2 INCHES
THROUGH THE PERIOD. THE GFS TRIES TO SHOW AN MCS MOVING IN FROM THE
NORTHWEST ON FRIDAY NIGHT INTO SATURDAY WITH A SHORT WAVE. WILL KEEP
SCATTERED POPS ONLY WITH THIS FEATURE. UPPER LEVEL FLOW WILL REMAIN
WEAK AS WELL...WITH THE UPPER JET STAYING NORTH. BY SATURDAY...THE
UPPER RIDGE AXIS WILL BE REDEVELOPING FROM THE WEST. WITH UPPER
RIDGE AROUND KEPT WITH LOW SCATTERED POPS DURING THE DAY AND MAINLY
ISOLATED POPS IN THE EVENING. THE GFS WAS GENERATING SOME
PRECIPITATION. SUNDAY THROUGH TUESDAY LOOKS GENERALLY DRY WITH LOW
CHANCES OF DIURNAL CONVECTION. SO WENT CLOSE TO LOW POPS ON
GUIDANCE. AS FAR AS THE TROPICAL FEATURE IS CONCERN SINCE IT APPEARS
TO STAY EAST OF THE REGION...GOING TO LOWER POPS APPEARS TO BE THE
ROUTE TO TAKE...SINCE WE WILL BE ON THE DRY SIDE. GENERALLY WENT
WITH WITH GUIDANCE TEMPS AND ADJUSTED DEWPOINTS AND SKY COVER A
LITTLE.
