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

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

...THUNDERSTORMS...
STRONG THUNDERSTORMS WILL BE POSSIBLE ALONG AND SOUTH OF THE I-20
CORRIDOR OVERNIGHT TONIGHT. A LOW IS EXPECTED TO DEVELOP ALONG
THE STALLED FRONT THAT WILL BE	ACROSS THE SOUTHERN PORTIONS OF
THE REGION OVERNIGHT TONIGHT. THIS WILL RESULT IN ANOTHER CLUSTER
OF THUNDERSTORMS TO TRACK EAST INTO THE ARKLAMISS FROM OUT OF THE
ARKLATEX REGION. INSTABILITY LEVELS AND WIND SHEAR WILL BE
MARGINAL OVERNIGHT TONIGHT...BUT THERE COULD BE ENOUGH FOR STRONG
THUNDERSTORMS TO DEVELOP WITH THE MAIN RISK BEING SMALL HAIL AND
WIND GUSTS TO 40 MPH.

AS THE LOW AND ASSOCIATED UPPER LEVEL DISTURBANCE CONTINUES TO
MOVE EAST TOMORROW THE FOCUS OF THUNDERSTORMS WILL SHIFT OVER THE
SOUTHEASTERN AREAS. THERE MAY BE ENOUGH INSTABILITY AND SHEAR FOR
AREAS MAINLY EAST OF I-55 AND SOUTH OF HIGHWAY 84 TO SUPPORT
STRONG THUNDERSTORMS TOMORROW AFTERNOON. MOST OF THE
THUNDERSTORMS SHOULD MOVE EAST OF THE AREA EARLY TOMORROW
EVENING.

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

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

...DAYS FOUR THROUGH SEVEN...TUESDAY NIGHT THROUGH SATURDAY...
A RATHER STRONG UPPER LEVEL SYSTEM...FOR EARLY MAY...WILL MOVE
ACROSS THE REGION TUESDAY NIGHT THROUGH EARLY THURSDAY. THIS
SYSTEM WILL MOVE INTO INCREASING MOISTURE AND INSTABILITY
RESULTING IN A COUPLE ROUNDS OF THUNDERSTORMS. DUE TO THE
STRENGTH OF THE SYSTEM...ANY ROUND OF STORMS WILL HAVE THE
POTENTIAL TO PRODUCE ISOLATED STRONG OR SEVERE THUNDERSTORMS.

.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 UNTIL THE MIDDLE OF NEXT WEEK.
