EF1 tornado in Washington County, Nebraska

The tornado caused tree damage to two farmsteads east of Winslow, which is in Dodge county, and destroyed half of a machine shed. Tree and outbuilding damage was also noted at a church parsonage along its path. The damage path was fairly narrow, generally 25 yards or less.

A warm front lifted north across the region during the afternoon and evening of May 29th followed by a weak cool front passage later that night. As the warm front passed, temperatures warmed into the lower to mid 80s and dewpoint temperatures climbed into the 65 to 70 degree range. The whole system was aided by an intense upper level low pressure area that moved from the eastern Rockies into the northern plains. The combination of the high instability in place, the 2 fronts and the upper level disturbance created conditions that were favorable not only for severe thunderstorms, a few of which were supercells that produced tornadoes, but also areas of very heavy rainfall that produced flash flooding that night and river and stream flooding that lasted a day or two later.
