420 PM EST FRI MAR 2 2012

THE NWS STORM PREDICTION CENTER HAS ISSUED A
TORNADO WATCH FOR PORTIONS OF

       EASTERN KENTUCKY
       SOUTHEAST OHIO
       WESTERN VIRGINIA
       WESTERN AND CENTRAL WEST VIRGINIA

EFFECTIVE THIS FRIDAY AFTERNOON FROM 420 PM UNTIL MIDNIGHT EST.

...THIS IS A PARTICULARLY DANGEROUS SITUATION...

DESTRUCTIVE TORNADOES...LARGE HAIL TO 1.5 INCHES IN DIAMETER...
THUNDERSTORM WIND GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE
POSSIBLE IN THESE AREAS.

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 75 STATUTE
MILES EAST AND WEST OF A LINE FROM 70 MILES SOUTH SOUTHEAST OF
JACKSON KENTUCKY TO 25 MILES EAST NORTHEAST OF PARKERSBURG WEST
VIRGINIA.  FOR A COMPLETE DEPICTION OF THE WATCH SEE THE
ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU2).

REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS.

OTHER WATCH INFORMATION...CONTINUE...WW 57...WW 58...WW 59...WW
60...WW 61...

DISCUSSION...MULTIPLE SUPERCELLS WITH A HISTORY OF TORNADOES OVER
CNTRL KY ARE EXPECTED TO SPREAD EWD INTO THE WATCH AREA LATE THIS
AFTERNOON INTO TONIGHT WITHIN EXPANDING WARM SECTOR OF INTENSIFYING
EXTRATROPICAL CYCLONE.  THOUGH REGION WILL REMAIN ON THE ERN
ENVELOPE OF STRONGER INSTABILITY...THE PRESENCE OF VERY STRONG
VERTICAL SHEAR AND ESTABLISHED SUPERCELL STRUCTURES INDICATES A HIGH
LIKELIHOOD FOR SIGNIFICANT TORNADOES.  SOME CONSOLIDATION OF
NRN-MOST SUPERCELLS INTO A FAST-MOVING BOW ECHO SYSTEM IS POSSIBLE
WHICH WOULD SIGNIFICANTLY ENHANCE THE POTENTIAL FOR WIDESPREAD
DAMAGING WINDS.  LARGE HAIL WILL ALSO BE POSSIBLE WITH ANY SUSTAINED
SUPERCELLS.

SURFACE AND ALOFT TO 1.5 INCHES. EXTREME TURBULENCE AND SURFACE
