Developing Tornado on RFD/FFD Interface Under Wall Cloud (Click to See Larger Version) |
Probe 1 can be seen just to left and north of tornado on blown-up image (click on image). Developing supercell near Clovis can be seen in background. A strong rear flank downdraft, very warm and moist, gusted through our position. We estimate sustained 45 to 50 knots. The tornado formed within 30 seconds or so after the RFD developed. The tornado was approximately 200 meters north of us. Note the dust cone at the center of the vortex. |
