MESOSCALE DISCUSSION 0183
  NWS STORM PREDICTION CENTER NORMAN OK
  0113 PM CST THU MAR 11 2010
 
  AREAS AFFECTED...CENTRAL FL PENINSULA
 
  CONCERNING...TORNADO WATCH 29...
 
  VALID 111913Z - 112015Z
 
  THE SEVERE WEATHER THREAT FOR TORNADO WATCH 29 CONTINUES.
 
  LATEST SFC ANALYSIS SUGGESTS A WEAK MESO LOW IS RIPPLING EAST ALONG
  THE BOUNDARY NEAR SUMTER COUNTY IN THE CNTRL FL PENINSULA.  THIS
  FEATURE WILL SOON BE DISPLACED OFF THE EAST COAST AS LLJ REFOCUSES
  DOWNSTREAM NEAR THE GA/SC BORDER.  IN THE SHORT TERM SQUALL LINE/MCS
  IS PROGRESSING STEADILY ESEWD AT ROUGHLY 25KT...PERHAPS A BIT
  QUICKER AT TIMES...WHICH WILL OVERSPREAD MUCH OF THE CNTRL PENINSULA
  BY 12/00Z.  18Z SOUNDING FROM MFL INDICATES WARM SECTOR BOUNDARY
  LAYER PARCELS ARE NOT INHIBITED AND NEAR-SFC BASED UPDRAFTS SHOULD
  BE COMMON WITHIN 70+ TEMPERATURE ENVIRONMENT.  NEEDLESS TO
  SAY...STRONG SHEAR REMAINS FAVORABLE FOR SUPERCELL DEVELOPMENT AHEAD
  OF SQUALL LINE AND ISOLATED TORNADOES ARE MORE LIKELY WITH THIS
  DISCRETE ACTIVITY.
