SPECIAL WEATHER STATEMENT...CORRECTED EXPIRATION TIME NATIONAL WEATHER SERVICE JACKSON MS 836 AM CST TUE DEC 25 2012 ...DANGEROUS SEVERE WEATHER OUTBREAK WITH THE POTENTIAL FOR STRONG...LONG TRACKED TORNADOES...IS LIKELY THIS AFTERNOON AND EVENING ACROSS PARTS OF NORTHEAST LOUISIANA AND CENTRAL AND SOUTHERN MISSISSIPPI... A POWERFUL STORM SYSTEM IS EXPECTED TO MOVE THROUGH THE MID-SOUTH REGION THIS AFTERNOON AND TONIGHT...AND PRODUCE AN ENVIRONMENT FAVORABLE FOR THE DEVELOPMENT OF SEVERE THUNDERSTORMS ACROSS CENTRAL AND SOUTHERN MISSISSIPPI...AND NORTHEAST LOUISIANA. AT THE PRESENT TIME...THE GREATEST RISK OF SEVERE WEATHER APPEARS AS THOUGH IT WILL BE SOUTHEAST OF A LINE FROM WINNSBORO LA...TO CANTON...TO MACON. TORNADOES...A FEW OF WHICH COULD BE STRONG AND LONG TRACKED...ALONG WITH DAMAGING WINDS OF 75 MPH AND HALF DOLLAR SIZED HAIL...ARE POSSIBLE WITH THE MOST INTENSE SEVERE THUNDERSTORMS. THE MAIN QUESTION STILL REMAINING WITH THIS SEVERE WEATHER EPISODE IS HOW FAR NORTH AND WEST THE THREAT OF SIGNIFICANT SEVERE WEATHER WILL SPREAD. THIS WILL BE CONTINGENT UPON HOW FAR NORTH A WARM FRONT CURRENTLY OVER SOUTHERN LOUISIANA AND MISSISSIPPI CAN MOVE THIS AFTERNOON. AT THIS POINT...THE AREA WITH THE HIGHEST CONFIDENCE FOR BEING SOUTH OF THE WARM FRONT IS IN THE AREA OF ENHANCED RISK OF SEVERE WEATHER OUTLINED ABOVE...BUT IT IS POSSIBLE THAT THE THREAT COULD SPREAD AS FAR NORTH AS THE GOLDEN TRIANGLE AREA AND PARTS OF NORTH CENTRAL MISSISSIPPI LATE THIS AFTERNOON AND EVENING. THE DELTA REGION...PARTICULARLY THE UPPER DELTA OF SOUTHEAST ARKANSAS AND FAR NORTHWEST MISSISSIPPI...HAS THE LEAST RISK OF SIGNIFICANT SEVERE STORM ACTIVITY. HOWEVER...HEAVY RAIN COULD CAUSE FLASH FLOODING THERE AND ANYWHERE ACROSS THE REGION TODAY. THIS IS A POTENTIALLY DANGEROUS WEATHER SITUATION. PEOPLE ARE URGED TO ENSURE THEY HAVE A WAY TO GET WEATHER WARNING INFORMATION AS THEY GO ABOUT THEIR CHRISTMAS ACTIVITIES TODAY AND THIS EVENING.

THESE STORMS WILL DEVELOP AS A STRONG AREA OF LOW PRESSURE MOVES THROUGH THE ARKLAMISS DELTA REGION DURING THE AFTERNOON AND EVENING HOURS. THE MAGNITUDE AND AREAL EXTENT OF THE SEVERE WEATHER THREAT WILL GREATLY DEPEND ON HOW FAR NORTH A WARM FRONT ASSOCIATED WITH THE LOW PRESSURE CAN MAKE IT INTO THE REGION. IF THE WARM FRONT PUSHES NORTH OF THE AREA...A SIGNIFICANT SEVERE WEATHER EVENT WOULD BECOME MORE LIKELY...WHILE IF THE FRONT STAYS SOUTH OF THE AREA THE THREAT FOR SEVERE WEATHER WILL BE REDUCED. IN ADDITION TO THE SEVERE WEATHER THREAT...HEAVY RAINFALL IS ALSO EXPECTED ACROSS THE AREA. WIDESPREAD RAINFALL OF 2 TO 3 INCHES...WITH LOCALIZED HEAVIER AMOUNTS...IS ANTICIPATED. WITH INTENSE DOWNPOURS OF RAIN EXPECTED...SOME FLASH FLOODING COULD OCCUR. A WIND ADVISORY IS IN EFFECT TONIGHT AS NORTHWEST WINDS OF 25 TO 30 MPH WITH GUSTS TO 40 MPH WILL DEVELOP GENERALLY ALONG THE MISSISSIPPI RIVER AND WEST. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW. .SPOTTER CALL TO ACTION STATEMENT...
