   URGENT - IMMEDIATE BROADCAST REQUESTED
   TORNADO WATCH NUMBER 83
   NWS STORM PREDICTION CENTER NORMAN OK
   750 PM CDT FRI MAR 27 2009
   
   THE NWS STORM PREDICTION CENTER HAS ISSUED A
   TORNADO WATCH FOR PORTIONS OF 
   
          SOUTHEAST LOUISIANA
          SOUTHERN MISSISSIPPI
          COASTAL WATERS
   
   EFFECTIVE THIS FRIDAY NIGHT AND SATURDAY MORNING FROM 750 PM
   UNTIL 200 AM CDT.
   
   TORNADOES...HAIL TO 2.5 INCHES IN DIAMETER...THUNDERSTORM WIND
   GUSTS TO 80 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE
   AREAS.
   
   THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 95 STATUTE
   MILES EAST AND WEST OF A LINE FROM 35 MILES NORTH OF JACKSON
   MISSISSIPPI TO 35 MILES EAST SOUTHEAST OF INTRACOASTAL CITY
   LOUISIANA.  FOR A COMPLETE DEPICTION OF THE WATCH SEE THE
   ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU3).
   
   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 78...WW 79...WW 80...WW
   81...WW 82...
   
   DISCUSSION...COMPLEX AND DANGEROUS SITUATION UNFOLDING ACROSS THE MS
   DELTA REGION TONIGHT. TWO INTENSE CLUSTERS OF CONVECTION WITH
   EMBEDDED SUPERCELLS ARE UNDERWAY ALONG RETURNING WARM
   FRONT/OUTFLOW....ONE NOW NEAR ALLEN PARISH AND ANOTHER OVER AMITE
   COUNTY MS. INCREASINGLY STRONG SLY LOW LEVEL FLOW IN ADVANCE OF
   DEEPENING LARGE SCALE CYCLONE ACROSS THE ARKLATEX REGION WILL
   CONTINUE TO AID WARM MOIST INFLOW INTO THIS CONVECTIVELY ACTIVE
   REGION FOR SEVERAL MORE HOURS. EARLIER EVENING SOUNDINGS SUGGESTED
   THAT LOW LEVEL FLOW WAS RELATIVELY LIMITED TO SUSTAIN MORE INTENSE
   UPDRAFT ROTATION. HOWEVER...NOT ONLY IS THAT EXPECTED TO CHANGE
   DRAMATICALLY OVER THE NEXT FEW HOURS BUT THE EARLIER SOUNDINGS
   PROBABLY DID NOT ADEQUATELY SAMPLE THE LOW LEVEL SHEAR NEAR THE
   FRONT AND WEAK SUB-SYNOPTIC LOWS COINCIDENT WITH THE MOST VIGOROUS
   CONVECTION. THUS...STORMS WILL CONTINUE TO HAVE THE POTENTIAL TO
   PRODUCE TORNADOES...ALONG WITH VERY LARGE HAIL. EVENTUALLY...EXPECT
   ADVANCING COLD FRONT TO SUPPORT MORE SQUALL LINEAR DEVELOPMENT WITH
   DAMAGING WINDS LIKELY LATER TONIGHT.
   
   AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
   SURFACE AND ALOFT TO 2.5 INCHES. EXTREME TURBULENCE AND SURFACE
   WIND GUSTS TO 70 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO
   550. MEAN STORM MOTION VECTOR 24030.
