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

.DAY ONE...TONIGHT AND FRIDAY...

...THUNDERSTORMS...
ISOLATED SEVERE THUNDERSTORMS WILL BE POSSIBLE LATE TONIGHT AND
FRIDAY MORNING ACROSS EXTREME SOUTHEAST ARKANSAS AND PORTIONS OF
CENTRAL MISSISSIPPI ALONG AND NORTH OF A LINE FROM CROSSETT
ARKANSAS TO DE KALB MISSISSIPPI. SCATTERED SEVERE THUNDERSTORMS
WILL BE POSSIBLE LATE TONIGHT AND FRIDAY MORNING ACROSS NORTHEAST
LOUISIANA AND THE REMAINDER OF CENTRAL MISSISSIPPI.

A VERY STRONG UPPER LEVEL DISTURBANCE WILL CONTINUE TO DEEPEN AND
MOVE EAST THROUGH THE CENTRAL UNITED STATES THIS AFTERNOON AND
EVENING. THIS WILL SEND A COLD FRONT ACROSS THE AREA LATE TONIGHT
INTO FRIDAY MORNING. IT APPEARS THAT ENOUGH MOISTURE AND
INSTABILITY WILL BE AVAILABLE ALONG AND JUST AHEAD OF THE COLD
FRONT TO INTERACT WITH STRONG FORCING ALOFT TO GENERATE A LINE OF
SEVERE THUNDERSTORMS.

AT THIS TIME IT APPEARS THE BEST MOISTURE RETURN...AND THE BEST
PROSPECTS FOR SURFACE BASED THUNDERSTORMS...WILL EXIST ROUGHLY
ALONG AND SOUTH OF THE INTERSTATE 20 CORRIDOR. IN THIS
AREA...DAMAGING STRAIGHT LINE WINDS...HAIL IN EXCESS OF THREE
QUARTERS OF AN INCH AND A FEW TORNADOES WILL BE POSSIBLE. ACROSS
NORTHERN PORTIONS OF THE AREA...IT IS MORE UNCERTAIN IF
THUNDERSTORMS CAN BECOME ROOTED AT THE SURFACE. THE PRIMARY RISK
OF SEVERE WEATHER IN THIS AREA WILL BE LARGE HAIL. HOWEVER...AN
ISOLATED DAMAGING WIND GUST AND A TORNADO OR TWO CANNOT BE RULED
OUT IN AREAS ALONG AND WEST OF A LINE FROM CROSSETT ARKANSAS TO
GREENWOOD MISSISSIPPI.

...NON PRECIPITATION...
GUSTY WINDS WILL SPREAD ACROSS THE AREA ON FRIDAY BEHIND A STRONG
COLD FRONT. A STRONG PRESSURE GRADIENT WILL EXIST OVER THE LOWER
MISSISSIPPI RIVER VALLEY REGION AS LOW PRESSURE MOVES OFF TO OUR
NORTHEAST AND HIGH PRESSURE BUILDS IN FROM THE WEST. SUSTAINED
WINDS OF 15 TO 20 MPH WILL BE COMMON WITH FREQUENT GUSTS UP TO 30
MPH.

.DAYS TWO THROUGH SEVEN...FRIDAY NIGHT THROUGH THURSDAY...

...DAYS TWO AND THREE...FRIDAY NIGHT THROUGH SUNDAY NIGHT...
NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

...DAYS FOUR THROUGH SEVEN...SUNDAY NIGHT THROUGH THURSDAY...
ANOTHER STRONG UPPER LEVEL SYSTEM AND COLD FRONT WILL APPROACH
THE REGION ON MONDAY. AS THE UPPER LEVEL WAVE SINKS FURTHER
SOUTH...WARM MOIST AIR WILL BE PUMPED INTO THE REGION. STRONG
UPPER LEVEL WINDS AT ALL LEVELS WILL HELP ADD TO THE STRENGTH OF
THE SYSTEM. A SURFACE WAVE WILL DEVELOP AHEAD OF THE BOUNDARY
MONDAY AFTERNOON...BRINGING A WAVE OF STORMS THROUGH THE REGION.
A LINE OF THUNDERSTORMS WAS EXPECTED TO DEVELOP ALONG THE RIVER
AND MOVE THROUGH THE AREA...COMBINED WITH RAPIDLY DECREASING
TEMPERATURES ALOFT THE POTENTIAL FOR HAIL AND WINDS WILL
INCREASE. AT THIS TIME THE AMOUNT OF MOISTURE AND INSTABILITY
REMAIN UNCERTAIN WITH THIS SYSTEM.

SINCE THIS IS A HOLIDAY WEEKEND PERSONS ARE ENCOURAGED TO
CONTINUE MONITOR WEATHER FOR FURTHER DEVELOPMENTS.

.SPOTTER CALL TO ACTION STATEMENT...
THE ACTIVATION OF STORM SPOTTERS...HAM RADIO OPERATORS...AND
EMERGENCY MANAGEMENT PERSONNEL...WILL LIKELY BE NEED AFTER
MIDNIGHT TONIGHT THROUGH FRIDAY MORNING IN SUPPORT OF SEVERE
WEATHER OPERATIONS. OTHERWISE...ACTIVATION IS NOT ANTICIPATED
THROUGH NEXT THURSDAY.
