Yes, the date is right; this was in the fall! Striking, banded supercell structure is on display in this slide, with a long tail cloud extending off to the right. The lack of precipitation in this storm was remarkable, with visibility through the entire base to the other side. Can you pick out the spot at left where the tornado is about to develop? The innocuous-looking little wall cloud at lower left actually was rotating rapidly.
