Damage surveys conducted Monday by the National Weather Service determined that the rare, late November tornado in south-central Nebraska was actually three separate tornadoes.
Mike Moritz, meteorologist for the weather service office in Hastings, said two separate storm cells spawned the Nebraska tornadoes: one dropping a twister near Upland and the other dropping two tornadoes, one near Red Cloud and a second near Lawrence.
The tornado near Upland lasted about a minute and reached a peak wind speed of about 70 mph, placing it in the EF0 category for strength.
East of Red Cloud, an EF1-rated tornado uprooted trees, destroyed an outbuilding, tossed over two irrigation pivots and caused other minor damage along its 2.4-mile path, according to the weather service. The weather service estimated that the tornado’s winds peaked at 95 mph.
About 20 miles northeast of Red Cloud, near Lawrence, the same storm dropped a weaker tornado, an EF0 with peak winds of 75 mph, according to the weather service. It traveled about 1.6 miles.
Moritz said it’s possible the parent cloud of the two tornadoes could have dropped additional twisters in a hopscotching fashion, but no additional damage has been found.
