Radar Depiction of Tornadoes near Thedford on June 25th, 2010

 On June 25th severe thunderstorms formed along a cold frontal boundary over the Nebraska Sandhills.  Three tornadoes were reported between 600 PM and 717 PM CDT. The cold frontal boundary helped horizontal vorticity (spin of the air) be ingested into the thunderstorm.  This horizontal rotation was then tilted into the vertical - helping create the weak but short lived tornadoes near Thedford.  For more descriptive detail on this event, and preliminary local storm reports - please click here
