FRANKLIN TN-520 AM CDT THU OCT 18 2007

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH ALABAMA AND
PORTIONS OF SOUTHERN MIDDLE TENNESSEE.

.DAY ONE...TODAY AND TONIGHT...

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS...
INCLUDING DAMAGING WINDS AND ISOLATED TORNADOES THIS
AFTERNOON IN NORTHWEST ALABAMA...AND TONIGHT OVER THE
ENTIRE AREA.

SOUTHERLY WINDS AHEAD OF A STRONG SYSTEM WILL CONTINUE
TO PUMP WARM AND HUMID AIR INTO THE CENTRAL TENNESSEE
VALLEY TODAY AND TONIGHT. WEAK TO MODERATE INSTABILITY
WILL CONTINUE TO GENERATE MAINLY SCATTERED SHOWERS AND
A FEW THUNDERSTORMS THIS MORNING.

AS SURFACE HEATING COMMENCES TODAY...ISOLATED TO
SCATTERED STRONG TO POSSIBLY SEVERE THUNDERSTORMS ARE
EXPECTED TO DEVELOP...MAINLY THIS AFTERNOON. AT THIS
TIME...THE LIKELIEST LOCATION FOR THUNDERSTORM
DEVELOPMENT WILL BE IN CENTRAL MISSISSIPPI INTO EXTREME
NORTHWESTERN ALABAMA. ANY STORMS THAT DEVELOP WILL BE
STEERED QUICKLY TO THE NORTHEAST AT ABOUT 40 MPH. THESE
STORMS MAY BE CAPABLE OF PRODUCING DAMAGING WINDS...
SMALL HAIL...AND EVEN ISOLATED TORNADOES.

A COLD FRONT WILL SWEEP ACROSS THE REGION TONIGHT...
PRODUCING A LINE OF THUNDERSTORMS POSING A THREAT FOR
DAMAGING WINDS AND ISOLATED TORNADOES. THE FRONT AND
STORM THREAT SHOULD PUSH INTO NORTHWEST ALABAMA SHORTLY
AFTER MIDNIGHT...CROSSING THE I-65 CORRIDOR BY 5 AM...
AND THEN PUSHING OUT OF NORTHEAST ALABAMA AND SOUTH
CENTRAL TENNESSEE DURING THE MID MORNING HOURS.

RESIDENTS OF THE TENNESSEE VALLEY SHOULD MONITOR FUTURE
UPDATED ON THE DEVELOPING WEATHER SITUATION.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...

THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW.

A COLD FRONT IS EXPECTED TO MOVE THROUGH THE TENNESSEE
VALLEY EARLY NEXT WEEK...BRINGING ANOTHER ROUND OF
SHOWERS AND THUNDERSTORMS TO THE AREA. GREAT UNCERTAINTY
STILL EXISTS WITH THE TIMING OF THIS FRONT. AT THIS
TIME...THE FRONTAL PASSAGE LOOKS MOST LIKELY TO OCCUR
LATE MONDAY INTO EARLY TUESDAY.

.SPOTTER CALL TO ACTION STATEMENT...

ACTIVATION OF STORM SPOTTERS AND EMERGENCY MANAGEMENT
PERSONNEL MAY BE REQUIRED.
