A large upper level storm system developed over the Dakotas on Sunday, November 27th. Abnormally warm and moist air (by November standards) streamed north through Kansas and Nebraska out ahead of the storm system. As the overall upper level system strengthened, there was a broad area of favorable lift within the moist warm sector across central Nebraska, which supported thunderstorm development as clouds cleared and the atmosphere became unstable.
Low level wind shear values were very high and there was just enough instability by afternoon to allow the thunderstorms to develop, strengthen, and even spin up a few tornadoes in the 4-5 p.m. CST time frame. With the shorter days of later fall, there was a limited window for these severe thunderstorms, and they quickly began to die off with the early onset of evening. Severe weather had largely ended by 5:30 p.m. CST Sunday evening.
Tornadoes were confirmed in Franklin County near Upland, Webster County near Red Cloud, and Nuckolls County near Lawrence. There were also a few nickel-quarter size hail reports in St. Paul, Red Cloud and near Lexington.
This event on November 27th marked the second-latest day of the calendar year that tornadoes occurred in the state of Nebraska, with the latest occurring on December 13, 1975, when tornadoes touched down in Thayer and Pawnee Counties. This was the 4th time since 2000 that a tornado occurred in the month of November in Nebraska.
Below is more information about the confirmed tornadoes that struck the area. Additional information may be added as it becomes available.
