MISSISSIPPI THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE JACKSON MS
1000 AM CST WED JAN 8 1997

A DEVELOPING STORM SYSTEM OVER THE GULF OF MEXICO IS SPREADING
ABUNDANT MOISTURE NORTHWARD OVER THE LOWER MISSISSIPPI VALLEY. THIS
MOISTURE IS RISING UP AND OVER A COLD LAYER OF AIR AT THE SURFACE...
BUT CAN STILL RESULT IN THUNDERSTORMS BECAUSE OF THE INSTABILITY OF
THE AIR ABOVE THE COLD AIR.

SOME OF THE THUNDERSTORMS TODAY AND TONIGHT MAY BECOME SEVERE... WITH
THE PRIMARY THREAT LARGE HAIL. HOWEVER... AS WARMER AIR BEGINS TO MOVE
NORTHWARD AT THE SURFACE FROM THE GULF OF MEXICO... STRONG SURFACE
BASED THUNDERSTORMS WILL BE POSSIBLE OVER THE SOUTHERN PART OF
MISSISSIPPI LATER TODAY AND TONIGHT AS WELL.

ACTIVATION OF STORM SPOTTERS...HAM RADIO AND EMERGENCY MANAGEMENT
PERSONNEL WILL LIKELY BE REQUIRED MAINLY OVER THE CENTRAL AND SOUTH
COUNTIES OF MISSISSIPPI TODAY AND TONIGHT.
