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

.DAY ONE...TONIGHT AND WEDNESDAY...

...THUNDERSTORMS...
SEVERE THUNDERSTORMS CAPABLE OF PRODUCING TORNADOES WILL BE
POSSIBLE ACROSS PORTIONS OF MISSISSIPPI TONIGHT...GENERALLY ALONG
AND EAST OF THE NATCHEZ TRACE...INCLUDING A LINE FROM GRENADA TO

A STRONG UPPER LEVEL LOW PRESSURE SYSTEM FROM THE WEST HAS
RESULTED IN WARM TROPICAL AIR SPREADING ACROSS THE AREA. ALTHOUGH
INSTABILITY IS WEAK IN THE TROPICAL AIRMASS...THERE WILL BE JUST
ENOUGH TO PRODUCE SEVERE THUNDERSTORMS. VERY STRONG WIND SHEAR
WILL CREATE A FAVORABLE ENVIRONMENT FOR STORMS TO BECOME SEVERE

THE RISK FOR SEVERE WEATHER WILL CONTINUE TO DIMINISH FROM THE
WEST.

...FLOODING...
A FLASH FLOOD WATCH REMAINS IN EFFECT TONIGHT FOR MUCH OF THE
OUTLOOK AREA ALONG AND EAST OF THE NATCHEZ TRACE. FLASH FLOODING
WILL BE POSSIBLE TONIGHT ALONG AND EAST OF THE NATCHEZ TRACE AS A
VERY MOIST TROPICAL AIRMASS SURGES NORTH AHEAD OF THE APPROACHING
UPPER LEVEL TROUGH. RAINFALL WILL BECOME VERY HEAVY AS A LINE OF
STRONG TO POSSIBLY SEVERE THUNDERSTORMS MOVE OVER THE AREA. REFER
TO THE FLASH FLOOD WATCH FOR MORE DETAIL.

...NON PRECIPITATION...
A LAKE WIND ADVISORY REMAINS IN EFFECT TONIGHT FOR THE OUTLOOK
AREA FOR SUSTAINED WINDS OF 20 TO 25 MPH WITH GUSTS TO AROUND 35
MPH. THIS WILL BE DUE TO A TIGHT PRESSURE GRADIENT OVER THE
REGION FROM A STORM SYSTEM MOVING ACROSS THE AREA TONIGHT.

.DAYS TWO THROUGH SEVEN...WEDNESDAY NIGHT THROUGH TUESDAY...

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 WILL LIKELY BE NEEDED THIS AFTERNOON AND
TONIGHT...OTHERWISE ACTIVATION SHOULD NOT BE NEEDED THROUGH NEXT
MONDAY OCTOBER 23.
