   Concerning...Tornado Watch 143...

   Valid 240108Z - 240215Z

   The severe weather threat for Tornado Watch 143 continues.

   SUMMARY...A corridor of relatively higher severe threat will exist
   across northern FL for the next hour or so.

   DISCUSSION...Recent radar signatures across northern FL show two
   more distinct updrafts embedded within the convective line over
   Lafayette, Suwannee, and Dixie Counties. Additionally, the remnant
   outflow boundary extends from roughly the Gilchrist/Dixie/Lafayette
   county intersection eastward-southeastward to about 25 miles south
   of SGJ. These more cell-in-line structures coupled with augmented
   lift and vorticity along the outflow boundary could result in a
   corridor of relatively higher severe potential. Primary threat is
   damaging wind gusts but brief tornadoes are also possible. Local
   southward expansion of the watch may also be needed to cover
   potential storm intensification along the southern end of the line.
