   Areas affected...Parts of central Indiana

   Concerning...Tornado Watch 99...

   Valid 030120Z - 030245Z

   The severe weather threat for Tornado Watch 99 continues.

   SUMMARY...The tornado and damaging-wind risk is spreading
   east-northeastward across central Indiana in Tornado Watch 99.

   DISCUSSION...The latest radar data from IND/VWX shows an intense
   bowing line segment with an embedded supercell structure tracking
   east-northeastward at around 60 kt across central IN. With
   moist/unstable inflow for this system (middle 60s dewpoints) and
   60-70 kt of line-orthogonal 0-6 km shear (pew IND VWP), this intense
   convection will continue to pose a risk of severe wind gusts
   (upwards of 80 mph) and embedded tornadoes. Isolated cells
   developing ahead of the main line will also pose a risk of
   tornadoes, large hail, and damaging winds. 

   Farther south, semi-discrete supercell clusters are also tracking
   east-northeastward within a very favorable environment (350-400
   m2/s2 effective SRH and around 1500 J/kg MLCAPE). This activity will
   continue to pose a risk of tornadoes, large hail, and damaging winds
   as it continues east-northeastward.
