THE HAZARDOUS WEATHER OUTLOOK FOR NORTH AND CENTRAL ALABAMA...

...SEVERE THUNDERSTORMS STILL POSSIBLE LATER TONIGHT...

THIS EVENING...A STRONG UPPER LEVEL DISTURBANCE CONTINUES TO
MOVE RAPIDLY EASTWARD OUT OF TEXAS AND OKLAHOMA...TOWARD ALABAMA.
THIS SYSTEM SHOULD APPROACH THE AREA BY AROUND MIDNIGHT TONIGHT...AND
MOVE ACROSS THE STATE BEFORE DAWN.  AT THE SURFACE...A STRONG WARM
FRONT STRETCHES EAST-WEST ACROSS CENTRAL MISSISSIPPI AND THE CENTRAL
COUNTIES OF ALABAMA.  THIS BOUNDARY SEPARATES WARM...UNSTABLE AIR OVER
THE SOUTHERN HALF OF ALABAMA...FROM COOLER...MORE STABLE AIR OVER THE
FAR NORTHERN COUNTIES.

AS THE UPPER LEVEL DISTURBANCE APPROACHES FROM THE WEST LATER TONIGHT...
SEVERE THUNDERSTORMS MAY DEVELOP NEAR THE WARM FRONT OVER CENTRAL
MISSISSIPPI...THEN MOVE EASTWARD ACROSS NORTHERN AND CENTRAL ALABAMA
DURING THE PRE DAWN HOURS.  IN RESPONSE TO THE STRONG UPPER LEVEL
SYSTEM...THE UPPER LEVEL WINDS OVER ALABAMA ARE EXPECTED TO BECOME
FAVORABLE FOR THE DEVELOPMENT OF SEVERE THUNDERSTORMS...OR EVEN
TORNADOES LATER TONIGHT.

SCATTERED SHOWERS AND THUNDERSTORMS ARE PRESENTLY OCCURRING OVER CENTRAL
ALABAMA...NEAR A LIVINGSTON TO SYLACAUGA TO ANNISTON LINE.  THE AIRMASS
IN THIS AREA IS MODERATELY UNSTABLE...AND THERE IS A CHANCE A FEW OF
THESE STORMS MAY BRIEFLY BECOME SEVERE THROUGH MIDNIGHT.  HOWEVER...A
BETTER CHANCE OF SEVERE WEATHER WILL EXIST OVER NORTH CENTRAL ALABAMA
AFTER MIDNIGHT TONIGHT.

AT THIS TIME...IT APPEARS THE BEST CHANCE OF SEVERE THUNDERSTORMS WILL
BE SOUTH OF A LINE FROM HAMILTON TO CULLMAN TO CHEROKEE...AND NORTH OF A
LIVINGSTON TO CLANTON TO ROANOKE LINE.  THE THUNDERSTORMS...IF THEY DO
DEVELOP...WILL MOST LIKELY AFFECT WESTERN ALABAMA BETWEEN MIDNIGHT AND
2 AM...AND THE EASTERN COUNTIES BETWEEN 2 AM AND 5 AM.  DAMAGING WINDS
WILL BE THE MOST LIKELY TYPE OF SEVERE WEATHER ENCOUNTERED...BUT
ISOLATED TORNADOES ARE ALSO POSSIBLE.

THIS WEATHER SITUATION REMAINS VERY UNCERTAIN...AS A NUMBER OF
ELEMENTS HAVE TO COME TOGETHER FOR THE DEVELOPMENT OF THE SEVERE
THUNDERSTORMS LATER TONIGHT.  EMERGENCY MANAGEMENT AGENCIES AND STORM
SPOTTER GROUPS THROUGHOUT NORTHERN AND CENTRAL ALABAMA SHOULD CONTINUE
TO MONITOR THE LATEST WEATHER CONDITIONS AND BE READY FOR POSSIBLE
ACTIVATION OVERNIGHT.  ACTIVATION OF STORM SPOTTERS AND EMERGENCY
MANAGEMENT PERSONNEL REMAINS LIKELY OVERNIGHT.
