\"\"The Fort Rucker, AL (KEOX) radar, well south of the storm of interest, shows strong azimuthal shear values up to 0.028 S-1.\u00a0 The maximum values are slightly offset to the north of the surveyed tornado track (pink line) likely due to distance from the radar.\u00a0 A mature hook echo is apparent in the reflectivity with a corresponding tight couplet in the 0.5 degree SRM.<\/p>\n

\"\" The Maxwell, AL (KMXX) radar, located closer and to the west the tornadic supercell, was also detecting strong azimuthal shear up to 0.021 S-1.\u00a0 An area of negative shear was located immediately to the south of the SRM couplet, along a weaker anticyclonic inbound-outbound interface.\u00a0 This corridor of blue shades to bright white was a bit distracting from the more important red to white positive shear associated with the cyclonic rotation. The maximum positive shear values were located exactly on the track of the surveyed tornado.\u00a0 Reflectivity and SRM KMXX data were similar to KEOX.<\/p>\n

\"\"Merged 0-2 km azimuthal shear provided an accurate location of the meso\/tornado and washed out the negative shear signal from the KMXX data. The shear values are lower than the single radar data.\u00a0 \"\"Merged 3-6 km azimuthal shear is displaced to the north of the tornado path (pink line).<\/p>\n

\"\"The merged 0-2 km rotation track has a very nice color scale (yellow to red to cyan) — key features really stand out.<\/p>\n
