| Low-level instability was extremely high -- in excess of 125 J/kg -- supportive of robust storm updrafts near the ground. | A measure of how much turning there was in the winds is shown here. Values over 200 m2/s2 are very high, supportive of low-level storm rotation. | Effective Sig TOR parameter -- a combination of many individual parameters -- showing how favorable the environment is for tornadic supercells. Values over 1-2 are very high for our region. |
