GREENSBURG, Kan.—Storm chaser Rob McBay and his wife, Valarie, came face to face with one of several EF-3 tornadoes that broke out across the plains of Kansas on May 18 just after 10 p.m. CT.
The roaring vortex, which the National Weather Service later reported grew to be half a mile wide and boasted winds of more than 140 mph, plowed its way northeastward less than a mile ahead of him, shaking his Jeep Compass with a rear flank downdraft he estimated to be more than 100 mph.
