.UPDATE...ADDED AVIATION SECTION FOR 06Z TAF'S.

&&

.AVIATION...BNA/CSV...LARGE AREA OF SHOWERS AND THUNDERSTORMS
RACING INTO MIDDLE TENNESSEE AHEAD OF A STRONG COLD FRONT.
EXPECT WIDESPREAD THUNDERSTORMS OVERNIGHT, WITH A MODERATE SEVERE
POTENTIAL. IN ADDITION TO LOW CIGS AND SOME LLWS, STRONG

&&

.PREV DISCUSSION... /ISSUED 851 PM CST SUN JAN 22 2012/

UPDATE...SEVERE THUNDERSTORMS ARE EXPECTED IN THE MID STATE
OVERNIGHT...AND ISOLATED TORNADOES ARE A REAL POSSIBILITY. A
LINE OF THUNDERSTORMS WAS OVER EASTERN ARKANSAS EARLY TONIGHT

FOR THE DEVELOPMENT OF ROTATING SUPERCELLS. TORNADO WARNINGS HAVE
ALREADY BEEN ISSUED TONIGHT BY THE WEATHER OFFICE IN LITTLE ROCK,
ARKANSAS AND DOPPLER SRM DATA HAVE SHOWN SOME IMPRESSIVE GATE-TO-
GATE COUPLETS WITH SOME OF THESE STORMS.

A SPECIAL WEATHER STATEMENT WAS RECENTLY RE-RELEASED ADVISING
MIDDLE TENNESSEANS TO REMAIN VIGILANT OVERNIGHT AND TO LISTEN FOR
SEVERE WEATHER WARNINGS.

HIGH HELICITY ENVIRONMENT CONTINUES IN DEVELOP IN THE MID STATE,
AHEAD OF APPROACHING COLD FRONT AND ALL PARTS OF OUR FORECAST
AREA REMAIN UNDER AN SPC SEVERE WEATHER OUTLOOK, RANGING FROM A
"SLIGHT RISK" OVER EASTERN SECTIONS TO A "MODERATE RISK" WEST.

HAVE UPDATED GRIDDED FORECAST DATA TO KEEP CONDITIONS CLOUDIER
LONGER (INTO THE MIDDLE PART OF MONDAY), AND HAVE MADE SOME CHANGES
TO HOURLY TEMPERATURE AND DEW POINT DATA TO FAVOR AN EASTWARD
PROGRESSION OF WHAT CURRENTLY SHOWS UP ON MSAS DATA (I.E., WARM
AHEAD OF MAIN LINE WITH ONLY MODEST COOLING AND LOWERING OF DEW
POINTS BEHIND IT).

EVEN THOUGH CHANGES TO ZFP ARE SMALL, WILL GO AHEAD AND SEND OUT
AN UPDATED ZFP SHORTLY.

TENNESSEE TONIGHT...

...CONDITIONS WILL FAVOR THE DEVELOPMENT OF ISOLATED TORNADOES...

...VIGILANCE IS ADVISED OVERNIGHT...

EARLY TONIGHT A LINE OF THUNDERSTORMS...SOME SEVERE...WAS PUSHING
ACROSS EASTERN ARKANSAS. THE NATIONAL WEATHER SERVICE IN LITTLE
ROCK, ARKANSAS ISSUED TORNADO WARNINGS FOR SEVERAL OF THESE
STORMS...AND DAMAGE TO HOUSES AND TREES REPORTEDLY OCCURRED NEAR
THE TOWN OF FORDYCE, ARKANSAS. CONDITIONS WILL REMAIN FAVORABLE
FOR THE DEVELOPMENT OF SEVERE THUNDERSTORMS...AND ISOLATED
TORNADOES...AS THIS LINE OF THUNDERSTORMS CONTINUES TO MARCH
EASTWARD INTO MIDDLE TENNESSEE LATER TONIGHT.

IT STILL LOOKS LIKE THE GREATEST CHANCE FOR SEVERE THUNDERSTORMS
AND ISOLATED TORNADOES IN THE MID STATE WILL BE AFTER MIDNIGHT.
NIGHTTIME TORNADOES ARE ESPECIALLY DANGEROUS SINCE DARKNESS MAKES
IT DIFFICULT TO SEE THEM. IN ADDITION...IT IS THE TIME WHEN MOST
PEOPLE ARE THINKING OF GOING TO BED.

NOW IS THE TIME TO REVIEW YOUR SEVERE WEATHER SAFETY PLANS. KNOW
WHERE YOUR SAFE SHELTER IS LOCATED AND HOW YOU ARE GOING TO
RECEIVE WARNINGS IF ONE IS ISSUED FOR YOUR AREA. A BATTERY POWERED
WEATHER RADIO IS ESPECIALLY USEFUL IF A POWER OUTAGE OCCURS. A
BATTERY POWERED FLASH LIGHT CAN ALSO COME IN HANDY.

TRAINED STORM SPOTTERS...EMERGENCY MANAGEMENT...ALONG WITH FIRE
AND LAW ENFORCEMENT OFFICIALS ARE URGED TO REPORT ANY SEVERE
WEATHER OR DAMAGE TO THE NATIONAL WEATHER SERVICE OFFICE IN
NASHVILLE.

PLEASE STAY TUNED FOR THE LATEST INFORMATION REGARDING THIS
POTENTIAL SEVERE WEATHER EVENT.
