Wider weather episode

On the morning of April 6th, a potent negatively tilted trough was noted on upper-air analyses with its trough axis extending from the central Rockies northwest into Washington State and British Columbia. A jet max was noted on the south side of this trough, with flow at 300 hPa approaching 150 knots. Over the course of the day, this trough ejected out into the central Plains, inducing intense surface cyclogenesis in the central High Plains. By 3 pm that afternoon, the surface low was situated in far southwestern Nebraska with central pressure less than 990 hPa. Extending south and east out of the low-pressure center, a pacific front moved out into the central Plains, initiating a line of strong to severe thunderstorms in south-central Nebraska and Kansas after 2:30 pm. These storms tracked northeast into eastern Nebraska, weakening with eastwards extent. Ahead of these storms, the synoptic gradient winds were also very strong, with gusts ranging from 50 to 70 miles per hour across eastern Nebraska and western Iowa. The strongest measured gusts came out of Jefferson County where a gust up to 67 miles per hour was measured and reported by the Emergency Manager. This warranted a high wind warning from the Omaha-Valley National Weather Service (NWS). Scattered reports of wind damage from this storm system, both convective and non-thunderstorm winds, were relayed to the NWS, primarily across eastern Nebraska. Several trees were reported to have blown down in addition to a roof being blown off of a hardware store in Knox County.
