well, last night was a rough night for North Texas, first Cowboys lost the game then bad weather hit the area with a few tornadoes touching down.
the cowboys part delay Fox prime time programing (this affected the entire Eastern and Central time zones), and the storms pretty much interrupted all network programing, but the worst part was, while all the NBC 5, WFAA Ch 8 and CBS 11 broke in during the commercial break until there was a tornado warning for Dallas and Tarrant counties, Fox 4 interrupted the Fox prime several times and they when that tornado warning hit, they never went back to Fox programming. so pretty much, last night's hour long Simpsons and The Mick did not air completely in the area and only smart parts were seen, while Family Guy was completely preempted in the DFW market all together and Fox 4 didn't re-air it either so those episodes are consider "lost" for the entire DFW market and will be airing in whole in the area when they re-air it when they have a week of weekend.
so pretty much, when severe weather strikes your area while it's TV prime time, do expect to watch your shows online or on demand to see them in whole because your local stations will cover the weather over airing the network's prime time programming
