Low Level SuperCell Circulation, Martin County, Texas, April 23, 2008


















The above two images were taken from a developing Supercell in southeastern Gaines/northwestern Martin County(s) at approximately 2240Z while positioned at the Seminole Pipeline Compressor (Patricia Station) along SH 349, 25 miles north of Midland, as viewed from south looking northwest. A ragged updraft region is noted with associated scud clouds. The third image is a capture of a well defined crisp wall cloud beneath the Rear Flanking Line (but tilted to main storm tower) and left of a RFD incisement with noted dust blowing from northeast to southwest at lower left. The fourth image captures the advancing RFD incising into updraft intake area and a small tail cloud at far right. The remaining images below are taken a short time later, approx-imately 2315Z on Ranch Rd 829 in north central Martin County looking to the southeast from behind the RFD and Clear Slot, viewing low level rotation with associated Scud clouds. Note on second to last image the strong RFD winds blowing sand across road. The final image is of a very low circulation center and Wall Cloud with rainbow on the left of image and Rear Flanking Line on right of image, as viewed from behind the RFD region. This Supercell was tornado warned by NWS/MAF with Doppler Radar.
