Marginal tornado threat for FL Panhandle
Posted by JAC on 11/10/2009, 6:26 am


MESOSCALE DISCUSSION 2173
  NWS STORM PREDICTION CENTER NORMAN OK
  0427 AM CST TUE NOV 10 2009
 
  AREAS AFFECTED...FL PANHANDLE...FAR SE AL AND FAR SW GA
 
  CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
 
  VALID 101027Z - 101200Z
 
  AN ISOLATED TORNADO THREAT MAY DEVELOP ACROSS THE FL PANHANDLE...FAR
  SE AL AND FAR SW GA EARLY THIS MORNING. THE THREAT IS EXPECTED TO
  REMAIN TOO MARGINAL FOR WW ISSUANCE.
 
  TROPICAL STORM IDA IS CURRENTLY LOCATED VERY NEAR THE MS COAST WITH
  A LARGE SHIELD OF RAIN LOCATED ON THE NERN SIDE OF IDA. THE SRN
  EXTENT OF THE RAIN SHIELD IS LOCATED ACROSS THE FL PANHANDLE WHERE
  CONVECTION IS MORE DISCRETE IN NATURE. THE CELLS EXTEND ABOUT 100
  STATUTE MILES OFFSHORE AND SHOULD GRADUALLY MOVE INLAND. OBJECTIVE
  ANALYSIS SHOWS THE SRN EXTENT OF A 50 TO 60 KT LOW-LEVEL JET LOCATED
  ACROSS THE FL PANHANDLE WHERE THE TALLAHASSEE WSR-88D VWP IS
  SAMPLING ABOUT 45 KT OF 0-1 KM SHEAR. THIS ALONG WITH THE DISCRETE
  NATURE OF THE CONVECTION MAY RESULT IN ROTATING STORMS THAT MOVE
  ONSHORE OVER THE NEXT 2 TO 4 HOURS. ALTHOUGH THE THREAT IS EXPECTED
  TO REMAIN MARGINAL...A BRIEF TORNADO CAN NOT BE RULED OUT EARLY THIS
  MORNING.
