Severe Thunderstorm Warning 32, NWS Jackson, MS

AREA FORECAST DISCUSSION...MESOSCALE UPDATE
NATIONAL WEATHER SERVICE JACKSON MS
759 PM CST WED MAR 05 2003

AN UPDATE TO THE FORECAST WILL BE FORTHCOMING.

ITS KIND OF A COMPLEX WEATHER PATTERN...AT LEAST BY LOOKING AT THE
SURFACE CHART.  AS OF 700 PM...THE FRONT ITSELF EXTENDED FROM
GREENWOOD MISSISSIPPI TO ABOUT ANHUAC TEXAS.  A COUPLE OF WAVES OF
LOW PRESSURE WERE LOCATED ON THE FRONT...ONE BETWEEN GREENWOOD AND
TUPELO...AND ANOTHER JUST WEST OF ALEXANDRIA LOUISIANA.  EAST FROM
THE MOST SOUTHERN SURFACE LOW WAS A WARM FRONT...WHICH EXTENDED
ACROSS SOUTH MISSISSIPPI...PRETTY CLOSE TO THE U.S. HIGHWAY 84
CORRIDOR.

NOW WITH THESE DETAILS OUT OF THE WAY...ANOTHER DISTURBANCE SWINGING
THROUGH THE ARKLATEX HAS ALREADY BEGUN TO FIRE MORE STORMS OVER EAST
TEXAS AND WEST LOUISIANA.  IN GENERAL...THE FRONT HAS SHOWN LITTLE
MOVEMENT OVER THE PAST COUPLE OF HOURS.  WITH THE LOW-LEVEL JET
EXPECTED TO STRENGTHEN NEAR THE AREA TONIGHT...850 MB THETA-E VALUES
WILL REMAIN AT OR ABOVE 320K.  IN ADDITION...WE SHOULD REMAIN UNDER
THE RIGHT ENTRANCE REGION OF THE UPPER JET (WHICH...BY THE WAY...HAS
WIND SPEEDS IN EXCESS OF 100 KNOTS).  ALL-IN-ALL...THIS SUGGESTS THE
POSSIBILITY OF ANOTHER ROUND OF SEVERE STORMS LATER TONIGHT.

SO HERES THE CURRENT GAMEPLAN.  AFTER COORDINATION WITH THE STORM
PREDICTION CENTER...TORNADO WATCH NUMBER 27 WILL BE ALLOWED TO
EXPIRE AT 8 PM.  HOWEVER...WITH THE POSSIBILITY OF MORE SEVERE
WEATHER (MAINLY AFTER 900 PM)...ANOTHER SEVERE WEATHER WATCH MAY BE
ISSUED FOR LATER TONIGHT.  STAY TUNED.

THIS UPDATE WILL MAINLY BE TO REMOVE THE TORNADO WATCH FROM THE
CURRENT TEXT FORECAST PRODUCT (ZONES AND STATE).  THE GRIDS APPEAR
TO BE IN DECENT SHAPE AND WILL NOT TWEAK THEM MUCH AT THIS TIME.

.JAN...
AR...NONE.
MS...NONE.
LA...NONE.

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE JACKSON MS
730 PM CST WED MAR 05 2003

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

.DAY ONE...TODAY AND TONIGHT...

...THUNDERSTORMS...
...ANOTHER ROUND OF SEVERE WEATHER WILL BE POSSIBLE LATER
TONIGHT...

ISOLATED SEVERE THUNDERSTORMS WILL BE POSSIBLE AFTER 9 PM ACROSS
EXTREME SOUTHEAST ARKANSAS...EAST LOUISIANA...AND MUCH OF

LATER TONIGHT WILL BE LARGE HAIL GREATER THAN THREE-QUARTERS OF
AN INCH IN DIAMETER AND DAMAGING WINDS IN EXCESS OF 60 MILES AN
HOUR.  IN ADDITION...A FEW TORNADOES CANNOT BE RULED OUT.

EARLY THIS EVENING...A COLD FRONT EXTENDED FROM GREENWOOD
MISSISSIPPI TO JUST WEST OF ALEXANDRIA LOUISIANA.  EVEN THOUGH
THE THREAT OF SEVERE WEATHER HAS TEMPORARILY DIMINISHED...ANOTHER
DISTURBANCE IN THE UPPER ATMOSPHERE IS FORECAST TO MOVE INTO THE
REGION AFTER 9 PM.  AS THIS DISTURBANCE INTERACTS WITH THE
EASTWARD-MOVING FRONT...PLENTY OF MOISTURE...AND POWERFUL JET
STREAM DYNAMICS TO RESULT IN THE POSSIBILITY OF SEVERE
THUNDERSTORMS ACROSS THE REGION.  WITH THE CHANGE IN WIND
DIRECTION AND SPEED WITH HEIGHT...OR WIND SHEAR...A FEW TORNADOES
WILL BE POSSIBLE...MAINLY NEAR ANY BOUNDARIES LEFT OVER FROM THE
THUNDERSTORMS THAT HAVE ALREADY OCCURRED.

SHOWERS AND THUNDERSTORMS HAVE ALREADY BEGUN TO DEVELOP ACROSS
EASTERN TEXAS AND WESTERN LOUISIANA WITH THE APPROACH OF THE NEXT
UPPER ATMOSPHERIC DISTURBANCE.	YOU ARE URGED TO KEEP ABREAST OF
THE WEATHER CONDITIONS TONIGHT AS THIS NEXT ROUND OF STORMS
APPROACHES THE AREA.

...FLOODING...
HEAVY RAINFALL...WHICH MAY RESULT IN THE PONDING OF WATER...WILL
BE POSSIBLE SOUTH OF A LINE FROM WINNSBORO LOUISIANA TO CANTON
AND DEKALB MISSISSIPPI.

ANOTHER UPPER ATMOSPHERIC DISTURBANCE WILL COMBINE WITH AN
EASTWARD-MOVING COLD FRONT AND A STRONG JET STREAM TO ALLOW
SHOWERS AND THUNDERSTORMS TO REMAIN A POSSIBILITY LATER TONIGHT.
WITH PLENTY OF GULF MOISTURE IN PLACE...HEAVY RAINFALL WILL
REMAIN POSSIBLE IN THE STRONGER THUNDERSTORMS LATER TONIGHT.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

.SPOTTER CALL TO ACTION STATEMENT...
THE ACTIVATION OF STORM SPOTTERS...HAM RADIO OPERATORS...AND
