Yikes! Two separate cells, appear pretty damn serious. The second storm - the one distinct from the one near DFW - was shown on television tossing semi-trailers stories high into the air. Pretty bad. EDIT: 2:15 p.m. CDT: Tornado-connected storm currently right over DFW. No tornado reported at the airport per-se, though had been reported in connection with the history of this cell. HOWEVER, severe hail (1-in., "quarter-sized") apparently bombarding the airport. Understatement from The Weather Channel: "this is not good news for the airplanes." Jeeze, this is all that AA, its planes and its customers needed. DFW under a ground stop. Delays currently at 160 minutes, expected to increase.
