The image above was just taken a moment ago, from the Memphis area radar. It shows a strong, likely tornadic, supercell to the Southeast of Oxford, Mississippi. This dangerous storm is moving Northeast at 60 mph. Hail the size of a grapefruit was recently reported in Batestville.
As you can see on the right half of the image (which is velocity or wind speed & direction mode), you can see the red (wind blowing away from the radar) pixels bumping right up next to the green (wind blowing toward the radar) pixels to the South of Oxford. This is where the radar is telling us the tornadic circulation is located.
Residents to the East and Northeast ahead of this dangerous storm should seek immediate shelter.
