0-6 km Bulk Shear (Southeast)
0–6 km bulk shear quantifies deep-layer wind shear from the surface through midlevels. Thresholds of ~30–40 kt support organized multicells, while >40–45 kt favors supercells. Combine with CAPE and low-level shear to anticipate storm mode, organization, and attendant hazards.
