Overview Map * Dows are blue disks * Dual lobes are 30 o min crossing: Green Blue: D8-D7 Dark Blue: D7-D6 * Light green polygons are where CI occurred and moved ENE. * Darker green polygons are where CI started. * Low-level blockage is shown as grey sectors for each radar. Dow7 blockage is by cab. D6 D7 D8

Dual Map for Gust Front and Kink Gust fronts (pink at 04:35, brown at 04:50) showing occluded structure and kink. The kink (path shown as red arrow) developed vortices, shown later. Dow7 elevations malfunctioned after 04:50, remaining above ~20 deg until 05:51. The EF-0 tornado was obscured by attenuation. D6 D7 D8 04:35 04:54 04:50 04:35 EF-0 tornado ~ 05:37

DOW views of CI Simultaneous (03:58) views of the result of three different CI events ahead of gust front (DBM top, VEL bottom) for each radar at about the same time at elevation 1 o. Each is centered at about the same geographic location. The E-W line through center progressively initiated from W to E. DOW-8 DOW-6 DOW-7

DOW views of Gust Front approaching Simultaneous view of gust front (DBM top, VEL bottom) for each radar at about the same time at elevation 1 o. All are centered at about the same geographic location. DOW-8 DOW-6 DOW-7

DOW views of Gust Front near D8, D7 DOW-8 DOW-6 DOW-7 Simultaneous view of gust front (DBM top, VEL bottom) for each radar at about the same time at elevation 1 o. All are centered at about the same geographic location. D6 is severely attenuated. Small spinups may be present within kink just W of D7.

Maximum low-level wind at each radar Wind maxes listed below are circled in black on sweeps. Note different speed scale for D7. Dow-8: -26 at Z = 56m (05:05), then +30 m/s at Z=40m (05:10) both apparently caused by same translating feature. Dow-7: -27 m/s at Z=13 m. Dow-6: No significant winds. DOW-8DOW-7
