Tuscaloosa Tornado 1/27/1994 Radar Imagery

Radar Images 2238Z

The 2238Z REF data showed the storm was weighted in the lowest levels, i.e., the highest reflectivities were at 0.5 and 1.5 deg elevations. 0.5 deg = 5 kft; 1.5 deg = 10 kft; 2.4 deg = 14.1 kft; and 3.4 deg = 19.1 kft. The echo top at this time was less than 35 kft.

Interestingly, a mesocyclone was detected by the meso algorithm at the end of the 2238Z volume scan. V<sub>r</sub> = 26 kts at 0.5 deg; 26 kts at 1.5 deg; 22 kts at 2.4 deg; 19 kts at 3.4 deg; and 21 kts at 4.3 deg. It was only a minimal mesocyclone from an operator's viewpoint (as determined by the chart under the glass at each PUP workstation).
