AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
1103 AM CDT FRI APR 30 2004

.UPDATE...LATEST SATELLITE AND RADAR IMAGERY AGAIN INDICATE THAT THE
MODELS ARE HAVING DIFFICULTY HANDLING THE CONVECTIVE ACTIVITY OVER
THE REGION THIS MORNING. MODEL PLACEMENT AND COVERAGE IS UNDERDONE.
LATEST RADAR IMAGERY SHOWS A LARGE AREA OF SHOWERS AND THUNDERSTORMS
DEVELOPING OVER LOUISIANA AND MOUTHERN MISSISSIPPI. LATEST SATELLITE
IMAGERY SHOWS TWO WELL DEVELPED OUTFLOW BOUNDARIES MOVING TOWARDS
EACHOTHER. IF CURRENT TRAJECTORY HOLDS...THEY SHOULD HIT EACHOTHER
HEAD ON OVER EASTERN LOUISIANA.

WHILE THE MODEL DATA CONTINUES TO UNDERESTIMATE THE PRECIPITATION
AMOUNTS AND COVERAGE...THEY DO APPEAR TO HAVE A PRETTY GOOD HANDLE
ON THE INSTABILITY AND SHEAR OVER THE REGION. HAVE UPDATED THE ZONES
TO INCREASE POPS AND CLOUDCOVER TODAY...AND HAVE LOWERED AFTERNOON
TEMPERATURES IN CENTRAL MISSISSIPPI. GIVEN THE HIGH MOISTURE AND
INSTABILITY AS WELL AS THE BOUNDARIES IN THE AREA...STILL THINK THAT
ISOLATED SEVERE THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON AND
EVENING...BUT NOT NEARLY AS MUCH SEVERE ACTIVITY AS LAST NIGHT. THE
MAIN CONCERN TODAY WILL BE FOR HAIL AND WINDS.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR CENTRAL MISSISSIPPI...
NORTHEAST LOUISIANA...AND EXTREME SOUTHEAST ARKANSAS

.DAY ONE...TONIGHT AND SATURDAY...

...THUNDERSTORMS...
THERE IS A SLIGHT CHANCE FOR SOME STRONG TO SEVERE THUNDERSTORM
ACTIVITY IN THE DELTA REGION AND OVER THE EASTERN PARISHES OF
LOUISIANA THIS EVENING. THE MAIN SEVERE THUNDERSTORM CONCERN WILL BE
FOR STRONG WINDS AND HAIL AS A SOUTHWARD MOVING OUTFLOW BOUNDARY
MOVES OVER A HIGHLY UNSTABLE AND MOIST  ATMOSPHERE. DUE TO WEAK
ATMOSPHERIC WIND PROFILE TODAY...SUPERCELL DEVELOPMENT IS NOT
ANTICIPATED THIS AFTERNOON.

THE REAL CONCERN DURING THE DAY ONE PERIOD WILL ACTUALLY COME
TOMORROW AS A STRONG...YET DISORGANIZED COLD FRONT MOVES INTO THE
REGION. BEGINNING AROUND NOON SATURDAY...STRONG TO SEVERE
THUNDERSTORMS ARE EXPECTED TO MOVE THROUGH THE REGION...STARTING
IN THE DELTA AS A SERIES OF BROKEN SQUALL LINES MOVES THROUGH THE
AREA. SOME BOWING SEGMENTS CAN BE EXPECTED. THE MAIN CONCERN FOR
THIS SYSTEM WILL BE FOR WINDS...HAIL AND FLASH FLOODING. GIVEN THE
ANTICIPATED WIND PROFILES...DO NOT EXPECT VERY MANY SUPERCELLS TO
DEVELOP.

GIVEN THE PRESENCE OF NUMEROUS BOUNDARIES OVER THE REGION...WHICH
COULD COMPLETELY ALTER THE ORGANIZATION OF THIS SYSTEM...AND
GIVEN THE WIDESPREAD DISAGREEMENT IN THE MODELS WITH THE PATH AND
ORGANIZATION OF THIS SYSTEM...THERE IS SOME UNCERTAINTY REGARDING
THE MAIN FOCUS OF THE CONVECTION.

...FLOODING...
IN ADDITION TO THE STRONG TO SEVERE THUNDERSTORM ACTIVITY THAT IS
EXPECTED TO OCCUR TOMORROW...SOME FLASH FLOODING IS ALSO
POSSIBLE...ESPECIALLY IN THE MISSISSIPPI DELTA REGION.
AGAIN...GIVEN THE UNCERTAINTY WITH THE PATH AND ORGANIZATION OF
THIS SYSTEM...AREAS SOUTH AND EAST OF THE DELTA SHOULD MONITOR
WEATHER CONDITIONS SATURDAY AFTERNOON AS WELL.

.DAYS TWO THROUGH SEVEN...SATURDAY NIGHT THROUGH FRIDAY...

...DAYS TWO AND THREE...SATURDAY NIGHT THROUGH MONDAY NIGHT...
AS THE FRONT SLOWLY MOVES THROUGH THE AREA ON SATURDAY EVENING
AND SUNDAY MORNING...A SERIES OF DISTURBANCES WILL MOVE NORTHWARD
ALONG THE FRONT. THIS WILL SERVE TO REFOCUS THE DEVELOPMENT AND
TRACKS OF THE SQUALL LINES. THE SEVERE CONCERNS WILL CONTINUE TO
BE FOR WINDS...HAIL AND FOR FLASH FLOODING. BY SUNDAY
MORNING...THE FOCUS OF THE ACTIVITY SHOULD SHIFT TO BE MOSTLY
EAST OF THE NATCHEZ TRACE.

THE PRECIPITATION SHOULD TAPER OFF SUNDAY EVENING AS THE FRONT
FINALLY MOVES TO THE SOUTHEAST AND OUT OF THE AREA. AN EXTENDED
PERIOD OF DRIER AND COOLER WEATHER SHOULD FOLLOW.

...DAYS FOUR THROUGH SEVEN...MONDAY NIGHT THROUGH FRIDAY...
NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

.SPOTTER CALL TO ACTION STATEMENT...
THE ACTIVATION OF STORM SPOTTERS...HAM RADIO OPERATORS AND
EMERGENCY MANAGEMENT PERSONNEL...IN SUPPORT OF SEVERE WEATHER
OPERATIONS...MAY BE NEEDED  SATURDAY THROUGH SUNDAY AFTERNOON...
OTHERWISE ACTIVATION IS NOT EXPECTED THROUGH 6 PM  FRIDAY MAY 7.
