Randy at our staging area as we get ready to set off for our afternoon chase.











Working our way south ahead of a tornado warned storm below.   Plan is to move below the storm and track Northeast as it moves past our position.














We arrived to observe the wall cloud work towards us from the Southwest.





















































Wall cloud below cross the highway.


















Wall cloud continues to move by our position. 














We decided to move east towards Gilmer, Texas then we would head North to re-engage the storm.























We stopped just south of the thunderstorm and observed the structure of the storm between lightening flashes.

We videotaped the night chase from just North of Gilmer to within a mile of the tornado crossing the road.

Below is the view of the rotation within the storm located at the hook portion of the base reflectivity.  Spotters had witnessed a tornado just west of our location. 















Preparing to pull over as rotation track is approaching the highway from the west.  Visible in the video capture below is the wall cloud just beyond the tree line.

The video capture below illuminated by the lightening shows the wall cloud beyond the service station.
