0-6 KM vetical shear is still pretty impressive over northern TX in the 35-50 KT range which does favor supercells, ad low level shear isnt all that bad either especially over the eastern part of the state w/ lowest 1 KM shear > 15 KT
Instability is great also w/ 100mb mean layer CAPE of up to 3500J and Li's as low as -10.
