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.=20

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.
