November 16, 2015 TX Panhandle Tornado Outbreak

I witnesed 4 large tornadoes near Pampa and Miami, TX after dark. A very potent trough was digging into the southwest. In response, a surface low deepened very rapidly in eastern CO. This low pulled up very moist Gulf moisture. With very steep lapse rates and plenty of sunshine, enough instability formed to make storms that formed just before sunset go insane.
