I read the news clip from CNN Student News with subtitles, April 12, 2013. However, I’m confused by the underlined parts in the following.
So while Fridays may be awesome, the severe weather moving across parts of the US this week is not. But it is leading off today`s show. Earlier in the week some states got hit with huge snowfalls….
(1) Why does the reporter emphasize “this week is not” and what does the sentence mean?
(2) What does “it is leading off today’s show” mean?
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
