   Areas affected...Central Florida

   Concerning...Tornado Watch 23...

   Valid 230032Z - 230200Z

   The severe weather threat for Tornado Watch 23 continues.

   SUMMARY...Severe/tornado risk is ongoing across central Florida.

   DISCUSSION...Current radar loop shows a broken band of
   severe/embedded supercell storms extending from near St. Johns
   County southwest to Pinellas County, roughly along the surface
   front/wind shift.  Meanwhile, isolated supercells continue shifting
   northeastward across central Florida ahead of this main band.  

   The overall environment ahead of the front/wind shift remains highly
   favorable for supercells (including potential for strong tornadoes,
   damaging winds, and large hail) per the evening TBW RAOB which
   reveals 1800 J/kg mixed-layer CAPE, 53 kt 0-1 km shear, and 0-6 km
   shear 74 kt.  Expect risk to remain roughly steady-state over the
   next couple of hours across central Florida -- and later into
   southern parts of the state -- as the front/wind shift advances
   east/east-southeast across the Peninsula.
