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

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

...THUNDERSTORMS...
STRONG THUNDERSTORMS WILL BE POSSIBLE ACROSS EXTREME SOUTHEAST
ARKANSAS...EAST LOUISIANA...AND MUCH OF MISSISSIPPI LATE THIS
AFTERNOON AND EVENING.	THE PRIMARY RISK FROM ANY STRONG STORMS
WILL BE WIND GUSTS AROUND 45 MILES AN HOUR AND HAIL SMALLER THAN
THREE-QUARTERS OF AN INCH.

A LARGE CONVECTIVE COMPLEX...OVER THE SOUTHERN PLAINS THIS
MORNING...IS EXPECTED TO WEAKEN AS IT HEADS INTO THE LOWER
MISSISSIPPI VALLEY TODAY.  THIS COMPLEX WILL PLACE SEVERAL
OUTFLOW BOUNDARIES OVER THE REGION...WHICH MAY SERVE AS A FOCUS
FOR THUNDERSTORM DEVELOPMENT BY THIS AFTERNOON.  WHEN COMBINED
WITH A WEAK TROUGH OF LOW PRESSURE IN THE UPPER ATMOSPHERE AND A
WARM...MOIST...AND UNSTABLE AIRMASS...SOME OF THESE THUNDERSTORMS
MAY BE QUITE STRONG.

BECAUSE STRONG THUNDERSTORM DEVELOPMENT MAY BE DEPENDENT UPON
WHERE THESE BOUNDARIES ARE LOCATED...IT IS DIFFICULT TO PINPOINT
THE EXACT LOCATION OF STRONG THUNDERSTORMS AT THIS TIME.  YOU ARE
ADVISED TO MONITOR LATER FORECASTS FROM YOUR NATIONAL WEATHER
SERVICE IN JACKSON.

MUCH OF THE THUNDERSTORM ACTIVITY IS EXPECTED TO WEAKEN A COUPLE
OF HOURS AFTER SUNSET.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY...

...DAYS TWO AND THREE...TUESDAY AND WEDNESDAY...
THE NATIONAL HURRICANE CENTER IS CURRENTLY ISSUING ADVISORIES ON
TROPICAL DEPRESSION NUMBER 3 OVER THE YUCATAN. THERE IS
CONSIDERABLE DISAGREEMENTS WITH THE TRACK AND STRENGTH OF THIS
SYSTEM BUT THE BEST FORECAST RIGHT NOW BRINGS TROPICAL DEPRESSION
NUMBER 3 UP TO TROPICAL STORM STATUS...NAMED CINDY...AND MAKING
LANDFALL JUST TO THE EAST OF CAMERON...LOUISIANA. AFTER LANDFALL
THE FORECAST CURVES THE SYSTEM INTO CENTRAL MISSISSIPPI. IF THIS
PROVES TO BE CORRECT A GOOD PORTION OF NORTHEAST LOUISIANA...AND
CENTRAL MISSISSIPPI COULD SEE TORRENTIAL RAINS AND GUSTY WINDS.
PLEASE STAY TUNED FOR FURTHER UPDATES ON THIS SITUATION.

...DAYS FOUR THROUGH SEVEN...THURSDAY THROUGH SUNDAY...
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 IS NOT ANTICIPATED THROUGH THE MORNING OF
