I was watching the radar late this evening in Nebraska. It looks like there is a tornado warned cell that passed through Chadron, in the northwestern part of the state. This storm is all by itself.
The vertical display shows cloud tops approaching 50,000 ft, which is high for it being after 11:00 pm.
Right now, the Tornado Warning was issued based on “radar indicated rotation” which is apparent in the Storm Relative Velocity (SRV) image. You can see there are pink targets next to light green targets on this SRV image.
At first glance, it may appear that the rotation is not strong. However, notice that we are a getting to be a long ways away from the Rapid City, SD radar site. We are looking higher in the cloud (farther from ground level), and likely not getting an accurate picture of what is happening in this location.
I have fond memories of Chadron. I stopped at their Walmart on more than one occasion, a nice stop for some weary travelers during the 2009 storm chase season. I hope the town was not affected by this storm.
I hope you have enjoyed this post.
