   Mesoscale Discussion 0127
   NWS Storm Prediction Center Norman OK
   1118 PM CST Sun Jan 22 2017

   Areas affected...Southern Florida

   Concerning...Tornado Watch 24...

   Valid 230518Z - 230715Z

   The severe weather threat for Tornado Watch 24 continues.

   SUMMARY...A broken band of strong storms continues moving slowly
   southeast across southern Florida.  Isolated severe/tornado risk

   DISCUSSION...Latest radar loop reveals roughly 20 kt southeastward
   progression of the band of storms which now extends from Indian
   River County to Collier County, while individual cells (some of
   which continue to exhibit weak low-level rotation) move quickly
   northeastward.  Extrapolation of current line movement suggests that
   the band will clear the coast/keys by 10-11 Z.

   Until the line moves offshore, risk for locally damaging winds/hail
   and a tornado or two will continue, as the pre-frontal environment
   (per evening raobs and the latest VWPs) remains supportive of
   updraft organization/rotation.
