MISSISSIPPI...

AN EXPLOSIVE SEVERE WEATHER SITUATION IS SETTING UP OVER MISSISSIPPI
AS NEAR RECORD HIGH TEMPERATURES ARE CREATING VERY UNSTABLE CONDITIONS
OVER THE AREA.  STRONG WINDS IN THE UPPER-LEVELS OF THE ATMOSPHERE AND
SEVERAL STRONG UPPER-LEVEL DISTURBANCES WILL FURTHER ENHANCE THE
SEVERE WEATHER POTENTIAL BY THIS AFTERNOON.  SEVERE WEATHER WAS
ALREADY BREAKING OUT OVER LOUISIANA AND WILL LIKELY MOVE INTO SECTIONS
OF AT LEAST WESTERN MISSISSIPPI THIS AFTERNOON.  TORNADOES
ARE A STRONG POSSIBILITY AS THIS WEATHER SYSTEM APPROACHES FROM THE
WEST.

PARTS OF NORTHERN MISSISSIPPI RECEIVED HEAVY RAINS YESTERDAY AND WITH
THE THREAT OF MORE HEAVY RAINS THIS AFTERNOON...A FLASH FLOOD WATCH
REMAINS IN EFFECT FOR THE NORTHERN THIRD OF THE STATE.

A VERY COLD ARCTIC AIR MASS CONTINUES TO SLIDE SOUTHEASTWARD INTO
NORTHWESTERN ARKANSAS AND NORTHEASTERN TEXAS EARLY THIS AFTERNOON.
THIS AIR MASS IS NOW EXPECTED TO ENTER SECTIONS OF NORTHWEST
MISSISSIPPI LATE TONIGHT...AND ALL BUT PERHAPS EXTREME SOUTHEAST
MISSISSIPPI DURING THE DAY SATURDAY.  TEMPERATURES WILL DROP SHARPLY
INTO THE 30S AND 40S AS THE ARCTIC FRONT PLOWS THROUGH THE STATE.

LINGERING PRECIPITATION SATURDAY AFTERNOON INTO SUNDAY WILL PROBABLY
BE IN THE FORM OF FREEZING RAIN AND DRIZZLE.  AT THIS TIME...THIS
FREEZING PRECIPITATION IS EXPECTED TO BE PATCHY...BUT COULD STILL
MAKE TRAVELING DIFFICULT DURING THE UPCOMING CHRISTMAS WEEKEND.
THOSE PLANNING TRIPS THIS WEEKEND ARE ADVISED TO KEEP UP WITH THE
LASTEST FORECASTS AND STATEMEDNTS.
