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

.DAY ONE...TONIGHT AND SUNDAY...

...THUNDERSTORMS...
ISOLATED SEVERE THUNDERSTORMS WILL BE POSSIBLE ACROSS THE ENTIRE
OUTLOOK AREA FOR THE REMAINDER OF THE AFTERNOON AND EARLY THIS
EVENING. THE PRIMARY RISK WITH THESE STORMS WILL BE DAMAGING
WINDS OF AROUND 60 MPH...ALTHOUGH LARGE HAIL AND ISOLATED
TORNADOES MAY ALSO BE POSSIBLE.

SCATTERED THUNDERSTORMS ACROSS SOUTHERN AND CENTRAL MISSISSIPPI
WILL CONTINUE THROUGH THE REMAINDER OF THE AFTERNOON AND INTO THE
EARLY EVENING HOURS. ALSO THIS EVENING A COLD FRONT WITH A
DEVELOPING SQUALL LINE WILL BEGIN TO APPROACH NORTHWESTERN
PORTIONS OF THE OUTLOOK AREA.

THE SCATTERED THUNDERSTORMS IN THE SOUTH HAVE DEVELOPED IN AN
AREA WITH MODERATE INSTABILITY AND GOOD SHEAR. THIS WILL ALLOW A
FEW STORMS TO REACH SEVERE LIMITS AND BRING A THREAT OF STRONG
STRAIGHT LINE WINDS AROUND 60 MPH. THERE IS ALSO A SMALL THREAT
OF AN ISOLATED TORNADO OR TWO DUE TO THE DECENT BUT WEAKENING
SHEAR.

TONIGHT THE RISK OF SEVERE WEATHER WILL THEN SHIFT TO THE
NORTHWEST AS A COLD FRONT APPROACHES. AT THAT TIME THE MAIN AREA
OF CONCERN WILL REMAIN NORTH AND EAST OF A LINE FROM SICILY
ISLAND...LOUISIANA TO YAZOO CITY TO GRENADA...MISSISSIPPI. THERE
WILL STILL BE JUST ENOUGH SHEAR...INSTABILITY AND FORCING TO GET
A FEW STORMS TO APPROACH SEVERE LIMITS WITH THE MAIN CONCERN
BEING DAMAGING STRAIGHT LINE WINDS.

THIS SQUALL LINE WILL WEAKEN OVERNIGHT AND THUS THE SEVERE RISK
WILL DIMINISH. THAT SAID THERE WILL STILL BE ENOUGH FORCING TO
GET A FEW STORMS TO APPROACH STRONG LIMITS ACROSS CENTRAL
MISSISSIPPI AFTER MIDNIGHT AND ACROSS SOUTHEASTERN MISSISSIPPI
AND CONTINUE THE POTENTIAL FOR STRONG WINDS IN EXCESS OF 40 MPH.

.DAYS TWO THROUGH SEVEN...SUNDAY NIGHT THROUGH SATURDAY...

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 TONIGHT AND SUNDAY. OTHERWISE
ACTIVATION IS NOT EXPECT THROUGH FRIDAY SEPTEMBER 29.
