Tuscaloosa Tornado 1/27/1997 Radar Imagery

Radar Images 2303Z

At 2303Z the reflectivity data had a definite spiral look to it, as the concavity on the southern flank became sharper. 55+ dBZ was no longer detected on the southern flank as it had been.

A velocity couplet was evident at 0.5 and 1.5 degrees, but it was up at 2.4 and 3.4 degrees that the V<sub>r</sub> equaled 41 and 36 kts respectively (the couplet was gate-to-gate). The storm-relative inbound velocities were 50+ kts at these two higher slices. A TVS was detected with this circulation at the end of the volume scan (around 2308Z).
