Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Lake Charles Mun, LA (KLCH), launched 12:00Z, 7.9 hours before the alert went out and 191 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
1045 AM CDT TUE JUN 3 2003

LATEST SATELLITE IMAGERY SHOWS THE UPPER LEVEL TROUGH DRAPED ACROSS
CENTRAL MISSISSIPPI ALONG A LINE THAT EXTENDS FROM MACON SOUTHWEST
TO BROOKHAVEN. THE SURFACE FRONTAL BOUNDARY EXTENDS ROUGHLY FROM
MERIDIAN SOUTHWEST TO MONTICELLO. NEITHER THE GFS OR THE ETA MODEL
APPEAR TO BE HANDLING THE SOUTHEASTWARD PROGRESSION OF THIS SYSTEM
PARTICULARLY WELL. BOTH MODELS PROJECTED THAT THE SYSTEM WOULD STALL
FURTHER NORTH THAN IT HAS. BASED ON THE DISCREPANCY BETWEEN MODEL
AND REAL TIME DATA...ADJUSTED THE FRONTS POSITION...AND
CORRESPONDING PRECIPITATION...SLIGHTLY MORE TOWARDS THE SOUTHEAST
THAN WHAT THE MODELS INDICATED FOR TODAY. ZONE FORECAST HAS BEEN
UPDATED TO REFLECT THIS. HENRY

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE JACKSON MS
1057 AM CDT TUE JUN 03 2003

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

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

...THUNDERSTORMS...
GENERAL THUNDERSTORMS ARE POSSIBLE ACROSS ALL OF SOUTHEAST
ARKANSAS...NORTHEAST LOUISIANA...AND CENTRAL MISSISSIPPI TUESDAY.
A SLOW MOVING COLD FRONT APPROACHING THE ARKLAMISS TUESDAY
MORNING WILL MAKE ONLY GRADUAL PROGRESS INTO CENTRAL MISSISSIPPI
BY LATE AFTERNOON. THE AIR MASS ALONG AND AHEAD OF THE FRONT WILL
CONTINUE TO BE UNSTABLE...ESPECIALLY DURING THE AFTERNOON HOURS.
SCATTERED THUNDERSTORMS WILL BE MOST LIKELY SOUTH OF INTERSTATE
20 WHILE ACTIVITY ELSEWHERE IN THE AREA SHOULD BE MORE ISOLATED
IN NATURE. DURING THE EVENING...REMAINING SHOWERS AND
THUNDERSTORMS SHOULD BE CONFINED TO SOUTHEAST MISSISSIPPI AND
THESE ARE EXPECTED TO DIMINISH OVERNIGHT.

ALTHOUGH RELATIVELY HIGH LEVELS OF MOISTURE AND ATMOSPHERIC
INSTABILITY WILL PERSIST IN THE LOWER MISSISSIPPI VALLEY
TUESDAY...WIND FIELDS ALOFT AND SURFACE TEMPERATURES WILL BE
LOWER THAN THOSE EXPERIENCED MONDAY. THEREFORE...STORMS ACROSS
THE AREA ARE NOT EXPECTED TO BECOME SEVERE...BUT STILL COULD BE
CAPABLE OF BRIEF GUSTY WINDS...FREQUENT LIGHTNING...AND HEAVY
DOWNPOURS.

...FLOODING...
MOISTURE LEVELS TUESDAY ARE EXPECTED TO REMAIN PARTICULARLY HIGH
ACROSS SOUTHEAST MISSISSIPPI. STORMS FORMING IN THIS AREA WILL
HAVE AN ENHANCED POTENTIAL FOR PRODUCING HEAVY DOWNPOURS...AND
RAINFALL AMOUNTS WITH SOME STORMS COULD EXCEED ONE INCH. ALTHOUGH
WIDESPREAD OR MAJOR FLOODING IS NOT ANTICIPATED...PONDING OF
WATER UPON ROADWAYS AND OTHER LOW LYING AREAS IS POSSIBLE IN
SOUTHEAST MISSISSIPPI THROUGH TUESDAY EVENING.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY...

...DAYS TWO AND THREE...
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS EXTREME
NORTHEAST LOUISIANA...SOUTHEAST ARKANSAS...AND PORTIONS OF
NORTHWEST MISSISSIPPI LATE THURSDAY INTO FRIDAY MORNING.

A WEAK FRONTAL BOUNDARY WILL REMAIN BASICALLY STALLED NEAR THE
GULF COAST WEDNESDAY AND THURSDAY. THERE IS A SLIGHT CHANCE THE
BOUNDARY COULD BEGIN PUSHING BACK NORTH INTO THE LOWER
MISSISSIPPI VALLEY AS A WARM FRONT AS EARLY AS THURSDAY
AFTERNOON. IF THIS OCCURS THEN MID-LEVEL ENERGY FORECAST TO BE
MOVING THROUGH THE SOUTHERN PLAINS BY THIS TIME COULD TRIGGER
THUNDERSTORMS ALONG THE BOUNDARY...AS FAR EAST AS THE DELTA AREAS
OF NORTHEAST LOUISIANA...SOUTHEAST ARKANSAS...AND NORTHWEST
MISSISSIPPI. ATMOSPHERIC WIND FIELDS SHOULD BE SUFFICIENT TO
BRING ANY THUNDERSTORMS IN THIS AREA LATE THURSDAY AND FRIDAY
MORNING TO SEVERE LIMITS.

...DAYS FOUR THROUGH SEVEN...
ANOTHER WEAK COLD FRONT SHOULD MOVE INTO THE LOWER MISSISSIPPI
VALLEY LATE FRIDAY AND INTO SATURDAY. THE ATMOSPHERE ACROSS THE
AREA SHOULD BE MOIST AND UNSTABLE BY THIS TIME...BUT WIND FIELDS
ARE EXPECTED TO BE RELATIVELY WEAK...AS WELL AS THE UPPER LEVEL
DISTURBANCE ACCOMPANYING THE FRONT. THEREFORE...WIDESPREAD SEVERE
WEATHER IS NOT ANTICIPATED FRIDAY AFTERNOON AND INTO SATURDAY
ALTHOUGH ISOLATED STORMS ACROSS SOUTHEAST ARKANSAS...NORTHEAST
LOUISIANA...AND CENTRAL MISSISSIPPI DURING THIS TIME FRAME COULD
BE LOCALLY STRONG.

A STRONGER SYSTEM LOOKS TO AFFECT THE AREA LATER IN THE WEEKEND
WITH A MORE SUBSTANTIAL COLD FRONT NOW EXPECTED TO MOVE ACROSS
THE LOWER MISSISSIPPI VALLEY MONDAY. AT THIS TIME THERE IS A MUCH
GREATER POSSIBILITY THAT THE COMBINATION OF UPPER LEVEL
DYNAMICS...MOISTURE...AND WIND SHEAR ASSOCIATED WITH THIS SYSTEM
COULD BRING SEVERE WEATHER TO PORTIONS OF SOUTHEAST
ARKANSAS...NORTHEAST LOUISIANA...AND CENTRAL MISSISSIPPI.

.SPOTTER CALL TO ACTION STATEMENT...
THE ACTIVATION OF STORM SPOTTERS...HAM RADIO OPERATORS...AND
EMERGENCY MANAGEMENT PERSONNEL...IN SUPPORT OF SEVERE WEATHER
OPERATIONS...WILL NOT BE NEEDED FOR THE REST OF TODAY.
