Bucksnort Geography: Brandon (Langston Kerman), while providing radio broadcasts for the Nebraska Weather Service, gives tornado warnings to York, Polk, and Seward counties. These are actual Nebraska counties west and northwest of Lincoln and south and east of the established area of Bucksnort in Nance County, Nebraska.
While tornadoes can occur all year, they are most common in Nebraska during spring and early summer, where they develop along dry lines. Dry lines separate very warm, moist air to the east from hot, dry air to the west. Most twisters in the state occur in the afternoon or early evening as these dry lines move east.
Overall, the state is no stranger to tornadoes. Per NCDC's last averaging period (1991-2010), Nebraska's 57 tornado per year average came in fifth place behind Texas, Kansas, Oklahoma and Florida.
