For those not able to see it on radar yesterday, what occurred were some supercell thunderstorms. It started out as only a single one about 70nm due west of DFW
, and the cell was moving from 260 at 30, later 270 at 30. This supercell pretty much had the northern third of the Dallas-Fort Worth area in it's path (which included DFW
). As this cell approached DFW
, the othet two supercells formed up in the path of the original supercell, and followed it. It was the first and second of these three that whacked DFW
and dropped hail at the airport and surrounding suburbs. (The third supercell turned NE and went by DFW
's north side.) The hail was generally 2-3 inches in diameter, although some saw smaller, and some small larger.
The aircraft damage at DFW
was largely due to the hail's impacting upon various horizontal control services, most of which are made of compositite materials. While many aircraft were damaged, the event doesn't inititally appear to be as bad as the hailstorm that went through about 10 years earlier. In that event (with bigger hail) about 40-50 aircraft (IIRC) were damaged, with some being out-of-service for weeks.
